Figure Lengend Snippet: ( A ) Volcano plot of differentially accessible chromatin sites after 8 hours of YAP CA expression. Log 2 fold change > 2 indicates more accessible chromatin after YAP CA expression. ( B ) Motif analysis on differentially accessible chromatin loci. ( C ) Chromatin accessibility at locus proximate to Ctgf . ( D ) Chromatin immunoprecipitation of CTGF by YAP and TEAD in human cells. ( E ) Chromatin accessibility at locus proximate to Bmp4 . ( F ) Chromatin immunoprecipitation of BMP4 by YAP and TEAD in human cells. ( G ) Temporal dynamics of Yap and Bmp4 expression after 1, 4, 8, 12, 24, and 48 hours of doxycycline treatment. ( H ) Schematic for femoral osteotomies and periosteal cell isolation followed by MGH-CP1 treatment in vitro. ( I ) Bmp4 mRNA expression after 24 hours of treatment with 10 µm or 50 µm of MGH-CP1 in vitro. ( J ) Coimmunoprecipitation of TEAD with YAP in fracture-activated periosteal cells. IP, immunoprecipitation; IB, immunoblotting. ( K ) RNA in situ hybridization for Bmp4 in the periosteum of WT fl/fl and YAP/TAZcKO Osx mice. ( L ) Staining for Osx protein and DAPI in adjacent sections to sections in (K). Dotted lines indicate the periosteum. Scale bars, 100 μm. ** P < 0.01 and **** P < 0.0001.
