Platelet-derived growth factor isoforms prevent cell death during starvation of AKR-2B fibroblasts

Confluent AKR‐2B fibroblasts rapidly desintegrate upon removal of serum until a final density of ∼50% of the initial value was reached after 12 h. This density remained unchanged for at least 48 h. Platelet‐derived growth factor (PDGF)‐BB stimulated more than 95% of these cells to divide. PDGF‐AB or...
