Expression patterns of Bmps and Msx1. Wild-type and Fmn1Pro/Pro limb buds probed for RNA expression of Bmp2, Bmp4 and Msx1 by in situ hybridization. Arrowheads indicate increased expression of Bmp2 in the underlying mesoderm of the AER, the absence of expression of Bmp4 within the posterior mesenchyme and the expanded expression of Msx1 in the posterior mesenchyme. Embryonic stages are indicated below image panels. Abbreviations used: forelimb, F; hindlimb, H.
