After growth arrest at the entry of the S phase of the cell cycle, Ob1771 and 3T3-F442A cells, but not 3T3-C2 cells, accumulate lipoprotein lipase and pOb24 mRNA that are early markers of adipose conversion. Removal of the single- or double-thymidine block when cultured cells are present at low density leads first to DNA synthesis and growth resumption, then to a continuous proliferation and a rapid disappearance of these markers. By contrast, growth-arrested Ob1771 cells reinoculated at high density undergo a single round of cell division, maintain high levels of early marker(s) and acquire with time both glycerol-3-phosphate dehydrogenase and lipids. Thus, depending upon the conditions in culture, growth-arrested cells can undergo either a dedifferentiation leading to a loss of early markers or a terminal differentiation leading to the acquisition of late markers.
