Human fibroblast cell pellets are derived from cultured skin explants. Human fibroblast cell pellets are from a single donor. These cell pellets enable researchers to study skin diseases such as dermatitis, wound healing, and other diseases that are expressed in fibroblast at the molecular level. In addition, they may be used to study the development of skin and production of inducible pluripotent stem cells to study disease models. Fibroblasts are isolated from an individual who has been clinically diagnosed with an astrocytoma. Astrocytomas are cancers of the brain that arise from astrocytes.
