[Comparison of the development between the satellite cells of ALD and PLD muscles of adult chicken in vitro].
Satellite cells isolated from the anterior (slow) and posterior (fast) latissimus dorsi of adult chick were cultured separately in the absence of neural factors. The cells were observed under an inverted phase contrast microscope every day. The morphological changes of satellite cells, described by other workers, were seen in these cultures. Furthermore, the difference in the time course of development of the satellite cells from different muscles was found. That is, the transformation of the satellite cells of PLD into the myoblasts and the fusion of the latter delayed about 24 h as compared with ALD. The results support the idea that there may be an intrinsic developmental tendency in the myogenic cells of bird, since it proved possible to see the difference of the myogenic cells even in mononuclear phase.
