title: In vitro cartilage differentiation: modification of division cycle and effect of some polyanions.
abstract: A modification of division cell cycle under conditions of in vitro cartilage differentiation could be demonstrated. The frequency distribution of histograms showed that the G1 cells represented 50% of total cells number at zero time (i.e. in suspension before inoculation), 69% on day 2 and about 90% in following period of days 4, 6 and 14. Dextran sulfate and hyaluronic acid produced a conspicuous inhibition and the chondroitin sulfate as well as heparin exerted a moderate inhibiting effect on the cell proliferation.
