Fibroblasts are the most common types of mammary stromal cells. Mammary stromal cells differentiate into fibroblasts, adipocytes or vascular structures in a hormone- and substatum-dependent manner, and may explain the dramatic changes in stromal composition during both normal mammary gland development and tumorigenesis. The interaction between stromal cells and tumor cells is known to play a major role in cancer growth and progression. The Mammary stromal fibroblasts express and produce cytokines such as SF witch plays roles in mammary cancer.
HMF are isolated from human mammary tissue. HMF are cryopreserved at primary culture and delivered frozen. Each vial contains >5 x 10^5 cells in 1 ml volume. HMF are characterized by immunofluorescent method with antibodies to fibronectin, CD90 and vimentin. HMF are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HMF are guaranteed to further expand for 15 population doublings at the conditions provided by Creative Bioarray.
