Web28 de out. de 2015 · Mammary epithelial cells from milk are shed from the mammary epithelium. As such, they are no longer in contact with the extracellular matrix known to provide survival signals to MEC in the mammary tissue (Katz and Streuli, 2007). Moreover, they are not connected to each other by tight junctions. WebThe purpose of the present study was to characterize primitive epithelial progenitor populations present in adult normal human mammary tissue using a combination of flow cytometry and in vitro colony assay procedures. Three types of human breast epithelial cell (HBEC) progenitors were identified: luminal-restricted, myoepithelial-restricted and …
WebLuminal-cell-restricted, myoepithelial-cell-restricted, and mixed progenitors of the human mammary epithelium can be isolated by fluorescence-activated cell sorting of cells … WebRapidly growing primary cultures of normal human mammary epithelial cells (HMEC) were exposed to 1 microgram of benzo[a]pyrene (B[a]P) per ml for two or three 24-hr periods. The B[a]P-treated populations consistently contained cells displaying a longer period of active growth in culture compared to the untreated control 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 …
