Abstract
The sulfated mucopolysaccharide composition of the mammalian cell lines: HeLa, H.Ep.2, AV 3, WI-38, BHK and a cell culture of rabbit lung tissue is reported. It is shown that chondroitin sulfate AC and heparitin sulfate are the main mucopolysaccharides of the permanent cell lines whereas chondroitin sulfate B and heparitin sulfate are the major ones in the primary cultures, with no significant change in their relative concentrations up to seven generations. It is also shown that besides heparitin sulfate, chondroitin sulfate AC and chondroitin sulfate B are located at the surface of the cells. These results are in agreement with the earlier proposals that heparitin sulfate and chondroitin sulfate B might play a role in cell recognition and adhesiveness and that chondroitin sulfate AC might act as a stimulant of cell division.
