Lifeline® Normal Human Dermal Fibroblasts-Neonatal, Xeno-Free (HDFn-XF), when grown in FibroLife® Xeno-Free Complete Medium, provide an ideal xeno-free culture system to establish xeno-free human feeder layers for human pluripotent stem cell cultures or as a model to study wound healing, toxicology or basic cell biology.
Human Dermal Fibroblasts-Neonatal, passage 2, 5 days after inoculation with 2000 cells/cm2 (100X)
HDFn-XF are cryopreserved as primary cells to ensure the highest viability and plating efficiency. Our HDFn-XF are quality tested in FibroLife® Xeno-Free Complete Medium to ensure optimal growth over a period of at least 15 population doublings at rates equal to or greater than other commercially available media containing non-human proteins or supplements.
Lifeline® HDFn-XF are not exposed to antimicrobials or phenol red when cultured in FibroLife® Xeno-Free Complete Medium, an advantage since these supplements can cause cell stress and ” masking effects” that may negatively impact experimental results.
