Surface glycosaminoglycans and calcium distribution in 3T3 cells

Abstract
Resting [mouse fibroblast] 3T3 cells have relatively more sulfated glycosaminoglycans and Ca2+ in their cell coat than do growing or SV40-virus-transformed cells. Apparently the different Ca2+-binding capacity controls cellular activities by affecting the distribution of Ca2+ between the intra- and ecto-cellular compartments.
