Morphological, biochemical, and molecular biological characterization of a rat rhabdomyosarcoma cell line during differentiation induction in vitro.

1990

BA-HAN-1C is a clonal rat rhabdomyosarcoma cell line consisting of proliferating mononuclear tumor cells, some of which spontaneously fuse to form terminally differentiated postmitotic myotubelike giant cells. Exposure to retinoic acid resulted in an inhibition of proliferation and a marked increase in cellular differentiation. The number of myotubelike giant cells significantly increased, and about 30% of the mononuclear tumor cells exhibited morphological features of rhabdomyogenic differentiation which were not observed in the mononuclear cells of untreated cultures. Morphological differentiation was paralleled by an increase in total creatine kinase activity as a biochemical marker of d…
