WebIn simple words, an osteoblast builds the bone, whereas an osteoclast eats up the bone so that it can be reshaped into a stronger and resilient load-bearing structure. Other … Een osteoblast is een cel die botweefsel opbouwt door osteoïd en mineraliserende enzymen af te scheiden in de extracellulaire matrix. Osteoblasten zorgen voor de verkalking van deze matrix, de ossificatie. Daarnaast scheiden ze ook regulerende stoffen af die de osteoclast-functie controleren. Osteoblasten die in het beenweefsel ingebouwd raken, worden osteocyten genoemd. Deze cellen ontstaan uit osteoprogen onder invloed van groeifactoren (FGF, PDGF, TGF-β en and…
