背景(Background)
PDGF在早期发育阶段具有促有丝分裂作用,推动未分化间充质和一些祖细胞群的增殖。在成熟后期,PDGF信号传导与组织重塑和细胞分化以及与模式和形态发生相关的诱导事件有关。除了驱动间充质细胞增殖外,PDGF还被证明在发育过程中和成年动物中指导各种特化间充质和迁移细胞类型的迁移、分化和功能。该家族中的其他生长因子包括在血管生成和内皮细胞生长中具有活性的血管内皮生长因子B和C(VEGF-B、VEGF-C),以及在血管生成中也具有活性的胎盘生长因子(PlGF)。PDGF在胚胎发育、细胞增殖、细胞迁移和血管生成中起着重要作用。PDGF是成纤维细胞(一种结缔组织细胞)细胞分裂中的必需元素。众所周知,PDGF可以维持少突胶质祖细胞的增殖。血小板源性生长因子亚基B也称为PDGFB、FLJ12858、PDGF2、SIS、SSV、c-SIS,是血小板源性增长因子家族的成员。PDGFB可以作为同二聚体(PDGF-BB)或与血小板衍生生长因子α多肽(PDGF-AB)的异二聚体存在,其中二聚体通过二硫键连接。该基因的突变与脑膜瘤有关。
