WebIn the case of zebrafish, little is known about BMPs in inner ear development. It was reported that bmp2b, bmp4 and bmp7 are expressed in a discrete area of the otic epithelium, some of which correspond to sensory patches (Mowbray et al. 2001). However, the function of BMPs in semicircular canal development is still obscure. images of irish shamrock
