Fig. 7. Summary of the expression patterns of Bmp family ligands and receptors in the developing eye. The different stages of eye development (labelled underneath) are represented by the different line drawings. Dorsal is upwards. The distribution and approximate intensity of labeling for the different ligands and receptors is indicated by the colored stippling. The expression patterns of Bmp4, Bmp7, Alk3 and Alk6 are derived from in situ hybridization experiments presented in a prior publication (Furuta and Hogan, 1998). The distribution of Alk2 is based on antibody labeling (Yoshikawa et al., 2000) and our understanding of Bmpr2 distribution on the current analysis.
