Cell-free plasma-derived serum (PDS) is deficient in the platelet-derived growth factor and will not support the growth of 3T3 cells, fibroblasts, or smooth muscle cells. However, when PDS-containing medium is preincubated with endothelial cells, the medium becomes modified so that it will support growth. The activity produced by the endothelial cells results from a polypeptide of 10,000 to 30,000 daltons which has several features that differ from those of the platelet-derived growth factor, including heat instability and lack of adsorption to CM Sephadex.
无细胞血浆衍生血清(PDS)缺乏血小板衍生生长因子,无法支持3T3细胞、成纤维细胞或平滑肌细胞的生长。然而,当含PDS的培养基与内皮细胞预孵育时,培养基会发生改变,从而能够支持细胞生长。内皮细胞产生的活性物质是一种分子量为10,000至30,000道尔顿的多肽,它具有一些与血小板衍生生长因子不同的特性,包括热不稳定性和不吸附于CM Sephadex。
