Primary culture of goat mammary gland cells could be derived by outgrowth of migrating cells from fragment of tissue. Fibroblast and epithelial cells could be pured according to their different sensibility to trypsin. Complex cultures treated by 0.25% trypsin in Hanks' for 5~7min at 37℃, the dispersed cells were mainly fibroblasts,then the rest treated by 0.15% trypsin-0.02% EDTA in Hanks'for 5~8min at 37℃, the majority cells harvested were mammary epithelial cells.
