Mouse embryonic stem cells (mESCs) have the properties of self-renewal and pluripotency. Various signals and growth factors maintain their undifferentiated state and also regulate their differentiation. Glycosaminoglycans are present on the cell surface and in the cell matrix as proteoglycans. Previously, we and other groups reported that the glycosaminoglycan heparan sulfate contributes to both maintenance of undifferentiated state and regulation of mESC differentiation. It has been shown that chondroitin sulfate is needed for pluripotency and differentiation of mESCs, while keratan sulfate is a known marker of human ESCs or induced pluripotent stem cells. We also found that DS promotes neuronal differentiation from mESCs and human neural stem cells; however, the function of DS in the maintenance of mESCs has not yet been revealed. Here, we investigated the role of DS in mESCs by knockdown (KD) or overexpression (O/E) of the dermatan-4-O-sulfotransferase-1 (D4ST1) gene. We found that the activity of the ESC self-renewal marker alkaline phosphatase was reduced in D4ST1 KD mESCs, but, in contrast, increased in D4ST1 O/E mESCs. D4ST1 KD promoted endodermal differentiation, as indicated by an increase in Cdx2 expression. Conversely, Cdx2 expression was decreased by D4ST1 O/E. Wnt signaling, which is also involved in endodermal differentiation, was activated by D4ST1 KD and suppressed by D4ST1 O/E. Collectively, these results demonstrate that D4ST1 contributes to the undifferentiated state of mESCs. Our findings provide new insights into the function of DS in mESCs.

Introduction

Mouse embryonic stem cells (mESCs) are established from the inner cell mass at the blastocyst stage (Evans and Kaufman, 1981; Martin, 1981). They have the properties of self-renewal and pluripotency, which means that they are capable of differentiation into the three primary germ layers, endoderm, mesoderm, and ectoderm, via the epiblast and primitive endoderm. There are many studies showing that various signals and growth factors contribute to maintenance of undifferentiated state and regulation of differentiation in mESCs. Because the role of glycans in these processes has not been fully elucidated, we previously performed an RNA interference (RNAi) screen to identify glycosyltransferases essential for self-renewal and pluripotency in mESCs. To date, we have identified four glycan structures that are required to maintain the naïve pluripotent state: (1) LacdiNAc structure (GalNAcβ1-4GlcNAc) (Sasaki et al., 2011), (2) heparan sulfate (HS) (Sasaki et al., 2008, 2009; Hirano et al., 2012, 2013), (3) O-GlcNAc (Miura and Nishihara, 2016; Miura et al., 2018; Pecori et al., 2021), and (4) T antigen (Galβ1-3GalNAc) (Pecori et al., 2020).

Glycosaminoglycans (GAGs) such as HS are present on the cell surface and in the cell matrix as proteoglycans, consisting of GAG and a core protein. GAGs show diverse structures due to sulfation and have a characteristic disaccharide repeating structure. In addition to HS, keratan sulfate (KS), and chondroitin sulfate (CS)/dermatan sulfate (DS) are well-known GAGs. HS and CS/DS bind to the Ser residue of core proteins through a common linkage region, namely GlcAβ1-3Galβ1-3Galβ1-4Xylβ-O-ser (Sugahara and Kitagawa, 2000), while KS binds to core proteins via an N-linked or O-linked oligosaccharide (Funderburgh, 2002). Previously, we and other groups showed that HS contributes to maintenance of undifferentiated state and regulation of differentiation in mESCs by promoting Wnt, BMP, FGF, and Fas signaling (Johnson et al., 2007; Sasaki et al., 2008, 2009; Kraushaar et al., 2010, 2012; Lanner et al., 2010; Fico et al., 2012; Hirano et al., 2012, 2013). In addition, Izumikawa et al. (2014) reported that CS is required for pluripotency and differentiation of mESCs, while KS is known as a marker of human ESCs or induced pluripotent stem cells (Andrews et al., 1984; Pera et al., 1988; Adewumi et al., 2007; Kawabe et al., 2013). To our knowledge, however, the function of DS in mESCs has not been revealed yet.

In the synthesis of DS, epimerization from glucuronic acid (GlcA) to iduronic acid (IdoA) is initially carried out by dermatan sulfate epimerase (Maccarana et al., 2006) or dermatan sulfate epimerase-like (Pacheco et al., 2009) after synthesis of the CS chain (i.e., GlcA-GalNAc repeating disaccharide structure). Subsequently, dermatan-4-O-sulfotransferase-1 (D4ST1) (Evers et al., 2001) transfers sulfate to the C-4 hydroxyl group of GalNAc. Lastly, sulfate is transferred to the C-6-hydroxyl group of GalNAc and the C-2 hydroxyl group of IdoA by N-acetylgalactosamine-4-sulfate 6-O-sulfotransferase (GalNAc4S-6ST) (Ito and Habuchi, 2000) and uronyl-2-sulfotransferase (UST) (Kobayashi et al., 1999), respectively. While the GalNAc4S-6ST and UST sulfotransferases are common to both CS and DS, D4ST1 is specific to DS.

We previously reported that DS promotes neuronal differentiation from mESCs and human neural stem cells (Ogura et al., 2020). It is also known that D4ST1 is needed for neuronal differentiation from mouse neural stem cells (Bian et al., 2011). Moreover, D4ST1 deficiency is the cause of Ehlers-Danlos syndrome (EDS), a genetic connective tissue disorder with defects in skin, ligaments, articulation, internal organs, and blood vessels (Kosho, 2016; Malfait et al., 2017).

Here, therefore, we investigated the role of DS in the undifferentiated state of mESCs by knockdown or overexpression of D4ST1. We found that D4ST1 contributes to self-renewal of mESCs and D4ST1 knockdown induces endodermal differentiation by activating Wnt signaling. Our results provide new insights into function of DS in mESCs.

Materials and Methods

Cell Culture

The R1 mESC line (Nagy et al., 1993) was cultured on mouse embryonic fibroblasts (MEFs) in mESC culture medium [DMEM (Gibco), 15% FBS (Nichirei Bioscience, Inc.), 1% penicillin/streptomycin (Gibco), 0.1 mM 2-mercaptoethanol (Gibco), 1 mM non-essential amino acids (Gibco), and 1,000 units/ml of LIF (Oriental Yeast)]. MEFs were isolated from embryos at E14.5 and inactivated by the addition of 10 μg/ml of mitomycin C (Sigma).

Transfection

For transient knockdown (KD) of D4ST1 in mESCs, we generated siRNA expression vectors using pSilencer 3.1-H1 (Ambion). The siRNA sequences used for RNAi were designed as described previously (Ui-Tei et al., 2004) by using siDirect1 :

Egfp, 5′-GATCCCGCCACAACGTCTATATCATGGGGAAA ATCCATGATATAGACGTTGTGGCTTTTTTGGAAA-3′; D4S T1 KD1, 5′-GATCCCCAGCACTACTTCAAGTTCCTGTTTGG CTTCCTGTCACCAAACAGGAACTTGAAGTAGTGCTGTTT TTTA-3′; D4ST1 KD2, 5′-GATCCCTCCTCTTGCTAGGTCTGA ATCATTTGCTTCCTGTCACAAATGATTCAGACCTAGCAAG AGGATTTTTTA-3′; D4ST1 KD3, 5′-GATCCCCTTCAAGAT GTGCTACCTAAGGCTTCCTGTCACCTTAGGTAGCACATCT TGAAGTTTTTTA-3′. Egfp was used as a negative control.

We also generated a D4ST1 overexpression (O/E) vector using pCAGI-Puro (a kind gift of Professor Kumiko Ui-Tei). The vector was produced by using the pGEM® -T Easy Vector Systems (Promega) as described previously (Kamiyama et al., 2006). We used an empty vector as a control for the O/E experiments.

Before transfection, we replated the mESCs at 1 × 106 cells on gelatin-coated 60-mm culture dishes (NIPPON Genetics) containing LIF. After 16 h, the cells were transfected with 4 μg of siRNA expression vectors targeting D4ST1 (D4ST1 KD1 and D4ST1 KD2) or Egfp, or the D4ST1 O/E vector by using Lipofectamine 2000 (Invitrogen). At 1 day after transfection (TF day 1), transfected cells were selected by adding 2 μg/ml of puromycin (Sigma). We harvested the cells at TF day 2 for the D4ST1 O/E experiments or TF day 4 for the D4ST1 KD experiments.

Cell Proliferation Assay

D4ST1 KD mESCs at TF day 4 were replated at 8 × 103 cells per well on gelatin-coated 96-well plates (IWAKI) containing LIF. After 24 h, we counted the number of viable cells by using microscopy.

Alkaline Phosphatase Staining

The transfected mESCs were replated at 1.25 × 105 cells per well on gelatin-coated 24-well plates (NIPPON Genetics) containing LIF. After 5 days, we carried out ALP staining with a StemTAGTM Alkaline Phosphatase Staining Kit (Cell Biolabs, Inc.). ALP-positive colonies were counted by using microscopy.

Real-Time PCR

Total RNA was extracted from cells by using TRI Reagent® (Molecular Research Center, Inc.) and reverse-transcribed by using SuperScriptTM VILOTM Master Mix (Invitrogen). Real-time PCR was performed by using Quant Studio 12K Flex (Applied Biosystems). The relative amount of each mRNA was normalized against the amount of β-actin mRNA in the same sample. The primer sets for real-time PCR are listed in Supplementary Table 1.

Western Blotting Analysis

The transfected mESCs were lysed with lysis buffer (50 mM Tris–HCl pH 7.4, 150 mM NaCl, 1% Triton X-100, 5 mM EDTA, 1 mM Na3VO4, 10 mM NaF, and protease inhibitors). The protein samples (5–10 μg) were separated by 8% SDS-PAGE and transferred to PVDF membranes (Millipore). After blocking with 1% BSA/TBST, the membranes were incubated with primary antibodies. The membranes were then incubated with secondary antibodies and Amersham ECL Prime Western Blotting Detection Reagent (GE Healthcare Life Science) was used for detection. The antibodies are listed in Supplementary Table 2.

Statistical Analysis

Data were compared with unpaired two-tailed Student’s t-test or Dunnett test. Asterisks denote statistical significance (n.s., p > 0.05; p < 0.05; ∗∗p < 0.01; and ∗∗∗p < 0.001).

Results

D4ST1 Contributes to Self-Renewal of mESCs

To investigate function of DS in mESCs, we performed knockdown (KD) of D4ST1, which is the first sulfotransferase in the DS synthesis pathway (Figure 1A). We designed two constructs (D4ST1 KD1 and D4ST1 KD2), which expressed different siRNAs targeting D4ST1 mRNA, and one construct targeting Egfp as a negative control. After transfection of mESCs with these constructs, the decreased expression of D4ST1 mRNA and D4ST1 was confirmed by real-time PCR and western blotting, respectively (Figures 1B,C). Proliferation in D4ST1 KD mESCs was not changed as compared with control cells (Supplementary Figure 1). To determine self-renewal potential, ALP staining was performed for the D4ST1 KD1 and KD2 transfected mESCs. The number of ALP-positive colonies was reduced by D4ST1 KD, indicating that D4ST1 contributes to self-renewal of mESCs (Figure 1D). Furthermore, the expression of three pluripotent markers, Oct3/4, Nanog and Sox2, were decreased in D4ST1 KD mESCs (Figure 1E and Supplementary Figure 2). The expression of Klf2 was decreased, while that of Klf4 and Rex1 did not change significantly (Supplementary Figure 3). The amount of Nanog was also significantly decreased in D4ST1 KD mESCs (Figure 1F).

Those significantly different to the control by Dunnett test (B–F) or unpaired two-tailed Student’s t-test (G) are indicated as follows: ***p < 0.001; **p < 0.01; *p < 0.05.

We also examined the effect of overexpression (O/E) of D4ST1 in mESCs (Supplementary Figure 4A). The increased expression of D4ST1 mRNA and D4ST1 after transfection with the O/E vector was confirmed by real-time PCR and western blotting, respectively (Supplementary Figures 4B,C). In contrast to D4ST1 KD, D4ST1 O/E increased the number of ALP-positive colonies (Figure 1G), confirming that D4ST1 contributes to self-renewal of mESCs.

Endodermal Differentiation of mESCs Is Induced by D4ST1 KD

Next, we examined the expression of differentiation markers to determine which lineages are induced from mESCs by D4ST1 KD (Figure 2A and Supplementary Figure 2). In D4ST1 KD mESCs, the expression of two epiblast markers, Fgf5 and Otx2, was decreased. The expression of two mesoderm markers, T and Mixl, was also significantly decreased. In contrast to mesodermal markers, the expression of two endoderm markers, Sox17 and Cdx2, was significantly increased in D4ST1 KD mESCs, indicating that the endodermal differentiation was induced in D4ST1 KD mESCs. Expression of the primitive endoderm marker Gata6 was significantly increased, indicating that the differentiation to primitive endoderm was also induced in D4ST1 KD mESCs. However, expression of the ectoderm marker Mash1 was not changed by D4ST1 KD. Collectively, these results suggest that D4ST1 contributes to the pluripotency of mESCs.

The amounts of differentiation marker mRNAs (Fgf5, Otx2, T, Mixl1, Sox17, Cdx2, Mash1, and Gata6) were normalized to that of β-actin mRNA and are shown relative to the control (set to 1). (B) Real-time PCR analysis of Cdx2 in D4ST1 O/E at TF day 2. The amount of Cdx2 mRNA was normalized to that of β-actin mRNA and is shown relative to the control (set to 1). The values shown are means ± SD (N = 3). Those significantly different to the control by Dunnett test (A) or unpaired two-tailed Student’s t-test (B) are indicated as follows: ***p < 0.001; **p < 0.01; *p < 0.05.

We also analyzed the expression of Cdx2, a marker of hindgut (Beck et al., 1995; Sherwood et al., 2007), in D4ST1 O/E mESCs. The expression of Cdx2 was significantly decreased in D4ST1 O/E mESCs (Figure 2B). It has been reported that Cdx2 expression is required for differentiation of hindgut (Stringer et al., 2008). Thus, the significantly increased or decreased expression of Cdx2 in the respective D4ST1 KD or D4ST1 O/E mESCs indicates that D4ST1 might regulate endodermal differentiation, including differentiation to hindgut.

BMP Signaling Is Suppressed and Wnt Signaling Is Activated by D4ST1 KD

To analyze effect of D4ST1 KD on signaling pathways, we used western blotting to analyze several signaling components in D4ST1 KD mESCs. First, we examined the BMP/Smad1/5/8 signal, which contributes to self-renewal in mESCs by suppressing neural determination (Ying et al., 2003) and by up-regulating ERK-specific dual-specificity phosphatase 9 to reduce extracellular signal-regulated kinase activity, which is required for cell fate commitment (Li et al., 2012). Phosphorylated Smad1/5/8 was significantly decreased by D4ST1 KD (Figure 3A). Thus, the reduced activity of the ESC self-renewal marker ALP (Figure 1D) is caused by a decrease in BMP signal.

Histogram shows the mean densitometric readings of bands normalized to β-actin, and was shown relative to the control (set to 1). The representative bands of the loading control (β-actin) are the same as those in Figure 1C because the same samples were used for these analyses. (C) Western blotting analysis of Active-β-catenin in D4ST1 O/E mESCs at TF day 2. Histogram shows the mean densitometric readings of bands, which were normalized to β-catenin and are shown relative to the control (set to 1). The values shown are means ± SD (N = 3). Those significantly different to the control by Dunnett test (A,B) or unpaired two-tailed Student’s t-test (C) are indicated as follows: ***p < 0.001; *p < 0.05.

Second, we examined the Wnt/β-catenin signal which induces endodermal differentiation (Zhong et al., 2017) and subsequently the hindgut domain during primitive gut tube formation in mouse (Engert et al., 2013). Whereas the relative amount of Active-β-catenin was significantly decreased by D4ST1 O/E (Figure 3C), it was significantly increased (Figure 3B) by D4ST1 KD. We also analyzed the expression of Wnt signaling target genes in D4ST1 O/E mESCs; Lef1 was significantly decreased, while that of Axin2 and Cdx1 tended to be decreased (Supplementary Figure 5). These results demonstrate that D4ST1 KD induces endodermal differentiation and subsequent regionalization of the hindgut domain by activating Wnt signaling.

Discussion

In this study, we found that self-renewal and the undifferentiated state of mESCs were compromised by D4ST1 KD. In D4ST1 KD mESCs, self-renewal of mESCs was reduced and endodermal differentiation was induced. In particular, the expression of Cdx2, which is a hindgut marker, was significantly increased by D4ST1 KD and significantly decreased by D4ST1 O/E. Similarly, Wnt signal was activated by D4ST1 KD and suppressed by D4ST1 O/E.

It has been reported that Cdx2 is essential for determination of intestinal mesoderm or endoderm differentiation (Stringer et al., 2008). The endoderm and mesoderm arise from a transient common precursor cell population referred to as “mesendoderm.” The specification of endoderm requires Wnt/β-catenin signaling, which maintains the expression of Nodal, which in turn promotes the expression of a network of transcription factors within the endodermal lineage including Sox17 (Zorn and Wells, 2009). After endodermal linage determination, the gut tube is formed. The gut tube then becomes regionalized along the dorsal-ventral and anterior-posterior axes into broad foregut, midgut, and hindgut domains (Zorn and Wells, 2009). The Wnt/β-catenin signal also specifies the hindgut domain by inducing Cdx2 expression, which is required for both the hindgut and positioning of the foregut-hindgut boundary in mouse development (Sherwood et al., 2011). Therefore, our results demonstrate that D4ST1 contributes to the undifferentiated state of mESCs, and D4ST1 KD induces endodermal and subsequent hindgut differentiation by activating Wnt signaling (Figure 4).

Figure 4. D4ST1 contributes to the undifferentiated state of mESCs. D4ST1 contributes to self-renewal and the undifferentiated state of mESCs. Knockdown of D4ST1 causes promotion of endodermal differentiation by activation of Wnt signaling.

CDX2 is also required for intestinal development in human pluripotent stem cells, and WNT signaling similarly promotes endoderm-hindgut differentiation (Kumar et al., 2019). Although further investigation is needed to elucidate the function of D4ST1 in human development, D4ST1 deficiency is known to be one of the causes of EDS (Kosho, 2016). D4ST1-deficient EDS presents characteristic craniofacial features, multiple congenital contractures, and progressive joint and skin laxity. Of note, joints and dermis are tissues derived from mesoderm. In the present study, in contrast to endodermal markers, mesodermal markers were suppressed by D4ST1 KD. Thus, D4ST1 may contribute to mesodermal differentiation in humans. In addition, it has been reported that skin complaints are caused by disorganization of collagen networks due to decorin, a dermatan sulfate proteoglycan (DSPG) (Hirose et al., 2018). There are several DSPGs, including decorin, biglycan, and fibromodulin. Determination of the DSPG that contributes to differentiation of mESCs will be an interesting issue for future study.

Because D4ST1 is a sulfotransferase involved in DS synthesis, it is possible that DS regulates Wnt signaling. GAGs such as HS and CS play a key role in signal transduction as co-receptors or as trappers by binding signal ligands (Wang et al., 2017). For example, DS has been reported to interact with bFGF, FGF7, and EGF (Taylor et al., 2005; Bian et al., 2011). To our knowledge, however, binding of DS to Wnt has not been demonstrated. This is also an interesting issue for future analysis.

In conclusion, we have shown that D4ST1 is required for self-renewal and the undifferentiated state in mESCs and D4ST KD induces endoderm differentiation and subsequent hindgut differentiation by activating Wnt signals. This study provides new insights into function of DS in mESCs.
