31. It is possible that facial clefts are caused by a disorder in the migration of neural crest cells. 32. More than just axonal guidance, Ephs have been implicated in the migration of neural crest cells during gastrulation. 33. In 2005, Tomita transplanted neural crest stem cells from mammal hearts to the neural crest of chick embryos. 34. Dilution genes such as champagne and Sabino1, interrupt or limit the migration of melanocytes from the neural crest . 35. Gene knockdown of CD271 has also been shown to abolish neural crest stem cell properties of melanoma cells. 36. In 2005, Tomita transplanted neural crest stem cells from mammal hearts to the neural crest of chick embryos. 37. A malignant tumor of migratory neural crest ( ectomesenchyme ) remnants showing ganglionic, schwannian, melanocytic and rhabdomyoblastic differentiation. 38. Outside of the tightly regulated network of neural crest specifiers are two other transcription factors Twist and Id. 39. In the neuroblast phase of development ?-internexin is found in the neural tube and neural crest derived neuroblasts. 40. She has made great contributions to the field of developmental biology with her research on the neural crest .
