细胞分裂在细胞学中占有一定的地位。近年来人们对影响细胞分裂的因素进行了多方面的研究,尤其在内分泌学方面,受到了极大的重视。到目前为止,肾上腺素、考地松、雌性激素等,对细胞分裂影响的材料比较多些,而关于胰岛素对细胞分裂的研究资料,则比较贫乏。其中虽有Bullough和Eisa(1950)曾提及小白鼠皮下注射胰岛素可引起耳皮肤表皮细胞分裂率的降低,但由于所用动物只有6只小白鼠, Cell division occupies a certain place in cytology. In recent years, people have carried out various studies on the factors affecting cell division, especially in endocrinology, which have received great attention. So far, adrenaline, cortisone, estrogen, etc., on the cell division of the material more, and on insulin on cell division research data, is relatively poor. Although Bullough and Eisa (1950) mentioned that subcutaneous injection of insulin into mice may cause a decrease in the rate of epidermal cell division in the ear skin, since only 6 mice are used in the animal,
