Proliferation of human mammary epithelial cells (HMEC) is limited to a few passages in culture due to an arrest in G 1 termed selection or mortality stage 0, M0. A small number of cells spontaneously escape M0, continue to proliferate in culture, and then enter a second mortality stage, M1, at which they senesce.
WebClonal analysis shows that open cells, besides reproducing the same phenotype, can give rise to mixed colonies containing joined cells, thus indicating a pathway of in vitro differentiation. Epithelium cultured from human milk contains cells of two types distinguishable by morphology and keratin pattern. First, the "open" type comprises cells … WebThe concentration of Ca++ in culture media profoundly affected the growth and differentiation properties of normal human mammary epithelial cells in short-term culture. In media where Ca++ was above 0.06 mM, longevity was limited to an average of three to four cell divisions. The extended growth fraction (those cells able, to divide more than …
