A UCSC genome browser tracks showing representative replicate ATAC-seq and CUT&Tag at the Klf4 locus. BMP2-dependent NFRs at Klf4 locus were named as K1 to K6. K2 and K6 are shaded in green. B Dual luciferase assay showing the relative enhancer activity of K2 and K6 in MC3T3-E1. n = 3, ***P < 0.001, ****P < 0.0001. C Double immunofluorescence staining of KLF4 and SP7 in 4-week-old Bmp2fx/fx (BMP2-WT) and Sp7-Cre; Bmp2fx/fx (BMP2-cKO) femurs. The image part was shown in the sketch on the left. n = 3.
