自从有人猜想在成熟细胞中产生一种能调节细胞分化和增殖速度的信号物质以后,不久即从上皮等组织中分离和鉴定出一类能抑制其细胞分裂活性的抑制剂。这类物质被命名为抑制素(chalone)。近十几年来对它进行了比较广泛系统的研究。对它们的理化性质及其生物学作用有了较深入的了解。 Since it has been speculated that a signaling substance capable of regulating cell differentiation and proliferation rates can be produced in mature cells, a class of inhibitors capable of inhibiting its cell division activity will soon be isolated and identified from epithelial and other tissues. This type of material is named chalone. It has conducted extensive and systematic research on it in the past ten years. They have a deeper understanding of their physicochemical properties and their biological effects.
