Fig. 3. cas neural crest cells differentiate into cartilage in wild-type embryos. (A) Diagram of the transplant procedure. (B) At the 10-somite stage, a few FITC-labelled (green) premigratory neural crest cells were transplanted from a cas embryo into a wild-type host. (C) At 3 days, in similarly transplanted embryo, mandibular and hyoid cartilage can be seen close to the eye. (D) cas neural crest have contributed to these cartilages in a characteristic stack-of-penny arrangement. e, eye; h, hyoid; m, mandibular.
