Primary Normal Human Dermal Fibroblasts (NHDF) are isolated from the dermis of juvenile foreskin and are provided in a cryopreserved format. They can be used for wound healing studies and dermatological research to investigate diseases like scleroderma, fibrosarcoma, fibrosis, xeroderma pigmentosum, and histiocytoma. Moreover, fibroblasts are important for cancer research, tissue regeneration, and tissue engineering studies.Normal Human Epidermal Keratinocytes (NHEK) and Normal Human Epidermal Melanocytes (NHEM) cultured in M2 medium from the same donor are available on request.
Rigid quality control tests are performed for each lot of Human Fibroblasts. They are tested for cell morphology, adherence rate and cell viability. Flow cytometric analyses of the fibroblast specific antigen CD90 are performed for each lot. Growth performance is tested through multiple passages up to 10 or 15 population doublings (PD) under culture conditions without antibiotics and antimycotics. In addition, all cells have been tested for the absence of HIV-1, HIV-2, HBV, HCV, HTLV-1, HTLV-2 and microbial contaminants (fungi, bacteria, and mycoplasma).
Although tested negative for HIV-1, HIV-2, HBV, HCV, HTLV-1 and HTLV-2, the cells – like all products of human origin – should be handled as potentially infectious. No test procedure can completely guarantee the absence of infectious agents.
