Methods are taught for culturing mammalian cells, preferably human cells, to improve production of proteins, recombinant or endogenous. Methods are also provided for the growth and long-term survival of cell lines, particularly cell lines established from primary culture. Cell culture media are also provided, contained varying levels of selected amino acids, supplemented with various growth factors and trace elements. In additionally, the media are optionally serum-free, and preferably use an energy source other than glucose. The media are particularly suitable for the primary culture and long-term culture of human fetal cells.
所传授的方法用于培养哺乳动物细胞,最好是人体细胞,以提高重组或内源性蛋白质的产量。还提供了细胞系生长和长期存活的方法,特别是由原代培养建立的细胞系。还提供了细胞培养基,其中含有不同含量的特定氨基酸,并补充了各种生长因子和微量元素。此外,培养基还可选择不含血清,最好使用葡萄糖以外的能量来源。这些培养基尤其适用于人类胎儿细胞的初级培养和长期培养。
