Description
We compared Sox9-association at chondrocyte targets to a broad catalogue of regulatory indicators of chromatin organization and transcriptional activity to determine Sox9s direct regulatory actions in normal developing chondrocytes. Sox9-associated regions resolve into two distinct regulatory categories. Class I regions closely associate with transcriptional start sites (TSSs). Their targets reflect general regulators of basal cell activities that Sox9 engages indirectly though a likely association with the basal transcriptional complex. In contrast, Class II regions outside of the local TSS domains highlight evolutionarily conserved, active enhancers directing expression of chondrocyte specific target genes, though DNA binding of Sox9-dimers at target sites with sub-optimal binding affinity. The level of associated chondrocyte gene expression correlates with the number of enhancer modules around the target gene and grouping into super-enhancer clusters. Comparison of Sox9 programs between neural crest and mesoderm-derived chondrocytes points to similar modes of chondrocyte specification in distinct chondrocyte lineages. These data provide the first insight into mammalian Sox family actions at the genome scale in the vivo setting. The resulting enhancer sets provide a key resource for further dissection of the regulatory programs of mammalian chondrogenesis.

Description
Sp7/Osterix is a master regulator of osteoblast specification. To identify transcripts profile in Sp7 positive osteoblast, we performed RNA-seq on primary mouse calvarial cells obtained from Sp7-GFP reporter mice at P1. By hierarchical clustering using transcriptional profiles for chondrocytes and mouse embryonic fibroblasts (MEFs) together with the osteoblast data, we identified cell-type enriched gene expression signatures in osteoblasts, chondrocytes and MEFs. In conjunction with Sp7 ChIP-seq in osteoblast, we identified putative Sp7 targets which underlie the osteoblast regulatory program. Overall design: RNA-seq experiments with GFP-sorted Sp7 positive osteoblasts and chondrocytes isolated from wild-type rib cartilage at P1

Description
The objective of this study was to investigate the roles of GSK3 inhibitor CHIR99021 and MEK inhibitor PD0325901 on 2i-adapted mouse embryonic stem cells (ESCs) in serum-free conditions.Canonical Wnt signaling supports the pluripotency of mouse ESCs but also promotes differentiation of early mammalian cell lineages. To explain these paradoxical observations, we explored the gene regulatory networks at play. Canonical Wnt signaling is intertwined with the pluripotency network comprising Nanog, Oct4, and Sox2 in mouse ESCs. In defined media supporting the derivation and propagation of mouse ESCs, Tcf3 and -catenin interact with Oct4; Tcf3 binds to Sox motif within Oct-Sox composite motifs that are also bound by Oct4-Sox2 complexes. Further, canonical Wnt signaling up-regulates the activity of the Pou5f1 distal enhancer via the Sox motif in mouse ESCs. When viewed in the context of published studies on Tcf3 and -catenin mutants, our findings suggest that Tcf3 counters pluripotency by competition with Sox2 at these sites, and Tcf3 inhibition is blocked by -catenin entry into this complex. Wnt pathway stimulation also triggers -catenin association at regulatory elements with classic Lef/Tcf motifs associated with differentiation programs. The failure to activate these targets in the presence of a MEK/ERK inhibitor essential for mouse ESC culture suggests that MEK/ERK signaling and canonical Wnt signaling combine to mouse promote ESC differentiation.
