7 product FAQs found
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.
Yes, our primary cells are isolated from tissue using enzymatic digestion.
Primary cells are cells taken directly from living tissue (e.g., biopsy material) and established for growth in vitro. These cells have undergone very few population doublings and are therefore more representative of the main functional component of the tissue from which they are derived in comparison to continuous (tumor or artificially immortalized) cell lines, making primary cells a more representative model for the in vivo state.
Primary cells from different species may be used, allowing you to highlight potential differences between humans and preclinical test species. Before in vivo studies, mouse or rat cells can be used to refine doses and reduce the number of animals required for preclinical toxicology. Human cells can be used to determine the accuracy of extrapolating human data from an animal model.
