Multiple Bmps are expressed at the deltoid tuberosity. In situ hybridization analysis of the developing deltoid tuberosity at embryonic day 13.5 with antisense probes to (a) collagen 2, (b) Bmp5, (c) Bmp2, or (d) Bmp6 shows expression of multiple Bmps at the developing deltoid tuberosity (arrowheads). Control sense probes did not detect any appreciable signal (data not shown).
