人真皮成纤维细胞，成人 (HDFa)

Human Dermal Fibroblasts, adult (HDFa) (Cat. No. C0135C) and Human Dermal Fibroblasts, neonatal (HDFn) (Cat. No. C0045C) are primary human dermal fibroblasts isolated from adult skin and neonatal foreskin, respectively. They are cryopreserved at the end of the primary culture stage and not passaged.

HDF cells are grown in Medium 106 with the addition of Low Serum Growth Supplement.

We use various media and supplements for the various primary cells. Details can be found here (https://www.thermofisher.com/us/en/home/life-science/cell-culture/primary-cell-culture.html).

Cumulative population doublings are calculated from the seeding density and harvesting density from each culture level.

It varies a lot depending on the age of donor, size of tissues, locations, and conditions arrived to our facility. Sometime a small amount of tissue gives us many cells and sometimes a large amount of tissue gives us a very small lot. Typically, we can get 30-300 vials.
