Heparin-binding growth factor-2 (HBGF-2; also known as basic fibroblast growth factor) is mitogenic for most anchorage-dependent cells. It is shown here that HBGF-2 stimulates cell-substratum adhesion and neurite extension in the sympathetic nerve cell line PC12. When HBGF-2 is adsorbed to artificial extracellular matrices consisting of heparin or chondroitin sulfate, it causes the formation of cellular aggregates or circles of cells, respectively. HBGF-2 is also a nerve cell survival molecule, for it potentiates the survival of primary cultures of embryonic chick ciliary ganglion cells but not of embryonic neural retina cells. Finally, a series of synthetic peptides from the HBGF-2 sequence is described that selectively alter the biological effects of HBGF-2. The amphiphilic nature of one of these peptides is discussed with respect to its ability to stimulate cell adhesion.
肝素结合生长因子-2(HBGF-2;也称为碱性成纤维细胞生长因子)对大多数锚定依赖性细胞具有促有丝分裂作用。本文表明,HBGF-2可刺激交感神经细胞系PC12中的细胞-基质黏附及神经突延伸。当HBGF-2吸附到由肝素或硫酸软骨素组成的人工细胞外基质上时,分别会导致细胞聚集体或细胞环的形成。HBGF-2也是一种神经细胞存活分子,因为它能增强胚胎鸡睫状神经节细胞原代培养物的存活,但对胚胎神经视网膜细胞则无此作用。最后,描述了一系列来自HBGF-2序列的合成肽,它们可选择性改变HBGF-2的生物学效应。其中一种肽的两亲性就其刺激细胞黏附的能力进行了讨论。
