    • Physiologically active growth factors produced by melanoma and astrocytoma cell lines support continued proliferation of slow-growing cells such as melanocytes in the absence of other added compounds. WI-38, a fibroblast cell line derived from human embryonic lung, was the most active source of melanocyte growth factors. No melanocyte growth promoting activity was found in extracts of cultured neuroblastoma, renal cancer, normal keratinocytes or renal epithelium. Nerve growth factor, epidermal growth factor, melanocyte stimulating hormone, transforming growth factor - Beta, and platelet-derived growth factor lacked growth promoting activity for melanocytes. The presence of melanocyte growth factors and TPA together resulted in the strongest mitogenic activity for slow-growing cells such as melanocytes, permitting the recovery (at 20 days) of 4 to 20 times more cells than in factor or TPA alone. A synergistic or augmented effect is seen with TPA plus melanocyte growth factor.
    • 由黑素瘤和星形细胞瘤细胞系产生的生理活性生长因子在不存在其他添加化合物的情况下支持慢生长细胞如黑素细胞的持续增殖。 来自人类胚胎肺的成纤维细胞系WI-38是黑素细胞生长因子中最活跃的来源。 在培养的神经母细胞瘤,肾癌,正常角质形成细胞或肾上皮的提取物中未发现黑素细胞生长促进活性。 神经生长因子,表皮生长因子,黑素细胞刺激激素,转化生长因子-β和血小板衍生生长因子对黑素细胞缺乏生长促进活性。 黑素细胞生长因子和TPA的存在一起导致对于慢生长细胞如黑素细胞的最强有丝分裂活性,允许恢复(在20天)比单独因子或TPA高4至20倍的细胞。 TPA加黑素细胞生长因子可以看到协同或增强的作用。
