31. Butterfly eyespots are formed during embryogenesis as a result of a morphogenetic signaling center or organizer, called the focus. 32. This gene encodes a member of the bone morphogenetic protein ( BMP ) family and the TGF-beta superfamily. 33. BMP4, short for bone morphogenetic protein number 4, is a major factor in the initial formation of the bud. 34. The longer she stays in contact with the morphogenetic field, the less human and more animal she seems to become. 35. "' Growth factors "'include bone morphogenetic protein ( BMP ) and insulin-like growth factors. 36. The cell surface receptor through which GDF9 generates a signal is the bone morphogenetic protein type II receptor ( BMPR2 ). 37. BMP4 is a member of the bone morphogenetic protein family which is part of the transforming growth factor-beta superfamily. 38. At about 1 mm in size, further changes in the morphogenetic program of the mantle are reflected in the shell. 39. Using a battery of bioassays for bone formation, a systematic study was undertaken to isolate and purify putative bone morphogenetic proteins. 40. This gene encodes a member of the bone morphogenetic protein family which is part of the transforming growth factor-beta superfamily.
