Figure 12. Bmp2 acts downstream of canonical Wnt pathway to specify Sp7+/Col1A1+ osteoblasts.

Figure 12.

(a) Cartoon summarizing regulatory analysis of Sp7 locus by chromatin immunoprecipitation of H3-acetyl-K14, Smad1, endogenous Grhl3, or transiently expressed V5-GRHL3 from chromatin of immortalized E13.5 limb bud cell cultures grown in presence of recombinant BMP2 or Noggin. (b) QPCR analysis revealed BMP-dependent enrichment of these proteins at a putative consensus-binding motif for Grhl3 located at a (c) highly conserved genomic region ˜13 kb upstream of the Sp7 transcription start site. Data reflect mean ±distribution in two independent experiments.
