Abstract

Freshly isolated normal and tumor mouse mammary epithelial cells embedded within a collagen gel matrix undergo sustained growth when cultured for as long as 3 wk in a serum-free medium composed of a 1:1 (vol/vol) mixture of Hepesbuffered Ham's F12 and Dulbecco's modified Eagle's medium supplemented with insulin, epidermal growth factor (EGF), transferrin, bovine serum albumin fraction V, and cholera toxin. Of these additives, only insulin, EGF, and albumin are required for the growth of most normal cells. Albumin is not always an absolute requirement for growth but greatly enhances it. Lithium has been found to stimulate the growth of normal cells and can replace EGF. The collagen matrix culture system allows sustained growth of primary cultures of both normal and neoplastic mammary epithelium in serum-free conditions. This serum-free system will be useful in identifying and investigating the role of hormones, growth factors, and nutritional factors in regulating the growth of mammary epithelial cells.

摘要

新鲜分离的正常和肿瘤小鼠乳腺上皮细胞嵌入胶原凝胶基质中,当在由Hepes缓冲的Ham's F12和杜氏改良伊格尔培养基按1:1(体积/体积)混合组成的无血清培养基中培养长达3周时,会经历持续生长,该培养基补充了胰岛素、表皮生长因子(EGF)、转铁蛋白、牛血清白蛋白V组分和霍乱毒素。在这些添加剂中,大多数正常细胞生长仅需要胰岛素、EGF和白蛋白。白蛋白并非总是生长的绝对必需成分,但能极大地促进生长。已发现锂可刺激正常细胞生长并可替代EGF。胶原基质培养系统可使正常和肿瘤性乳腺上皮的原代培养物在无血清条件下持续生长。这种无血清系统将有助于鉴定和研究激素、生长因子及营养因子在调节乳腺上皮细胞生长中的作用。
