If a dermal fibroblast culture is treated with platelet-derived growth factor (PDGF), which consequence follows?

💡 Explanation

PDGF is a key signal for stimulating cell division and tissue repair. Because PDGF activates receptor tyrosine kinases, triggering intracellular signaling pathways that promote cell cycle progression, therefore fibroblast proliferation increases rather than decreases or triggering apoptosis.
