[Characteristics of the manifestation of the morphological signs of muscle differentiation in a suspension culture of myogenic cells].

With electron microscopy, cell elements were observed in a suspension culture of the chick embryo femoral muscle cells. The newly formed myosymplasts displayed no regular ultrastructure. A disturbance in the temporal sequence in myogenic steps was noticed, in addition to the appearance of uninucleated cells with a differentiated sarcomere zone.
