    • The present invention relates to a method of synchronizing epithelial cells into G.sub.0 phase, more specifically, a method of synchronizing epithelial cells into G.sub.0 phase characterized by culturing the cells in a synthetic medium for 5 days or more, wherein said synthetic medium is a medium with the lowered concentration of bovine fetal serum 5% or less and said epithelial cells is bovine mammary gland cells. Further, the present invention relates to a method of culturing cells characterized by using G.sub.0 phase synchronized cells obtained by the present invention, and a method of screening a related to differentiation and/or maturation of said cells by using G.sub.0 phase synchronized cells. The present invention is useful for easily synchronizing epithelial cells into G.sub.0 phase and for screening a factor related to differentiation and/or maturation of epithelial cells.
    • 本发明涉及将上皮细胞同步至G0期的方法,更具体地说,涉及将上皮细胞同步至G0期的方法,其特征在于在合成培养基中培养细胞5天以上,其中所述合成培养基为 牛胎儿血清浓度降低5%以上,所述上皮细胞为牛乳腺细胞。 此外,本发明涉及一种培养细胞的方法,其特征在于使用通过本发明获得的G0相同步细胞,以及通过使用G0相同步细胞筛选与所述细胞的分化和/或成熟相关的方法。 本发明可用于容易地将上皮细胞同步化为G0期并筛选与上皮细胞的分化和/或成熟有关的因子。
