Organotypic differentiation of trypsin-dissociated fetal rat intestine.

abstract：:The earliest muscle in zebrafish arises from iterated sets of two to six cells in each somite, the muscle pioneers (MP). MP develop synchronously in young trunk myotomes adjacent to the notochord, precisely where the horizontal myoseptum will form. They elongate without cell fusion and differentiate hours earlier than...
