最近,在多肽生长因子方面出现了研究高潮,这归功于分子生物学技术。使用这些技术能大量生产生长因子,使其作为商品或作为实验室研究工具。“生长因子”通常是指细胞合成和分泌的对邻近细胞的增生和分化具有调节作用的多肽。为方便起见,通常将激素限定在内分泌范围内,而不是副分泌 Recently, there has been a research climax in the field of polypeptide growth factors, thanks to molecular biology techniques. Using these techniques, growth factors can be produced in large quantities for use as commercial products or as a laboratory research tool. “Growth factor” generally refers to a polypeptide that modulates the proliferation and differentiation of neighboring cells synthesized and secreted by cells. For convenience, hormones are usually limited to endocrine rather than paracrine
