Decreased oxygen tension is the principal stimulus for renal Epo expression, yet Epo production decreases in CKD, which is associated with chronic hypoxia ( 33, 34 ). The fibroblast is the most common cell that creates collagen. This study shows that human dermal fibroblasts can be consistently and reproducibly expanded and genetically modified to serve as a source of cytokines or other gene products for gene therapy trials. The term open source refers to something people can modify and share because its design is publicly accessible.. what is the source of the modified fibroblasts? Recent faithful genetic lineage-tracing studies revealed that during development, the cardiac fibroblasts are derived from the epicardium and the endothelium, whereas in the adult heart, they constitute the cardiac injury-responsive resident fibroblast. 27:549-550 . Normal adult human skin contains at least three distinct subpopulations of fibroblasts, which occupy unique niches in the dermis. Funding Source - FDA OOPD. This is later replaced by the stronger, long-stranded type-I collagen, as evidenced in scar tissue. Quiescence and nuclear transfer improved the ability to produce transgenic animals. The cardiac fibroblast, which accounts for almost 90% of nonmyocyte cells in the heart, is the primary cell type that is responsible for the secretion of a majority of ECM components in the heart, such as collagens I, III, and IV and laminin and fibronectin.
