血小板源性生长因子(PDGF)在“凝血级联反应”过程中释放,对各种间充质细胞(包括骨膜细胞)具有促有丝分裂作用。细胞培养提供了研究这些影响的方法。在本研究中,研究了PDGF刺激静止的颅骨骨膜细胞进入G1期的能力,由新的蛋白质合成所示。在加入贫血小板血浆后,这些细胞随后进入S期,通过摄取3 H-胸苷指示。PDGF刺激后3小时,与留在血清饥饿培养基中的细胞相比,至少有18条蛋白质条带定量增加。这些新的蛋白质条带中的两个(31 K和45 K)需要转录。这些数据表明,在外渗的血液中的PDGF可能会刺激在损伤部位的完整骨膜下的附着骨形成。
Platelet-derived growth factor (PDGF), which is released during the "clotting cascade", has a mitogenic effect on a variety of mesenchymal cells including those of the periosteum. Cell culture provides a method of studying these effects. In the present study, PDGF was studied for its ability to stimulate quiescent calvarium periosteal cells to enter G1, indicated by new protein synthesis. After addition of platelet poor plasma, these cells later entered S phase, indicated by uptake of 3H-thymidine. Three hours after PDGF stimulation, there were quantitative increases of at least 18 protein bands as compared to cells left in serum starvation medium. Two of these new protein bands (31K and 45K) required transcription. These data suggest that PDGF in extravasated blood may stimulate appositional bone formation beneath intact periosteum at the site of injury.
