Life Technologies, a Thermo Fisher Scientific Brand, offers Human Dermal Fibroblasts, neonatal (HDFn) part number C-004-5C, described as primary human dermal fibroblasts isolated from neonatal foreskin, cryopreserved at the end of the primary culture, for research use only. Cryopreserved HDFn are intended for use by researchers investigating the molecular and biochemical bases of

various normal and disease processes. Not for use in diagnostic procedures.<ref>{{REFweb

Life Technologies, now a brand of Thermo Fisher Scientific, traces its roots back to 1962 with the creation of Grand Island Biological Company (GIBCO) in Grand Island, New York, making serum harvested from horses raised on their land. The original Life Technologies, Inc., a subsidiary of Dexter Corp., was founded in 1983 by the merger of Bethesda Research Laboratories, Inc. and GIBCO Corporation. In 2000, Life Technologies was bought out by Invitrogen. Eight years later, following Invitrogen Corporation’s acquisition of Applied Biosystems Inc., Invitrogen renamed itself, creating the new Life Technologies Corp. In 2014, Life Technologies became the fourth premier brand within Thermo Fisher, the world leader in serving science.<ref>{{REFweb

PromoCell offers Primary Normal Human Dermal Fibroblasts (NHDF), isolated form the dermis of juvenile foreskin or adult skin from different locations like the face, the breasts, the abdomen, and the thighs. 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.<ref>{{REFweb

The Human Adult Dermal Fibroblasts Manual, on the very first page, states: "Human Adult or Neonatal Dermal Fibroblast Cells", and explains in the introduction: "Neonatal dermal fibroblasts are isolated from the foreskins of healthy male newborns. The cells are isolated by centrifugal force following enzymatic treatment or from an explant culture."<ref>{{REFweb
