Abstract:
Recessive Dystrophic Epidermolysis Bullosa (RDEB) is a rare and severe genetic disease responsible for blistering of the skin and mucosa caused by a wide variety of mutations in COL7A1 encoding type VII collagen. We have generated Induced Pluripotent Stem Cells (iPSCs) from two RDEB patients' fibroblasts harboring homozygous recurrent mutations in COL7A1. Their pluripotent state was confirmed by gene and protein expression of stem cell markers OCT4, SOX2, TRA1/60 and SSEA4. Embryoid body formation followed by immunostaining and TaqMan scorecard analysis confirmed the capacity of RDEB iPSCs to differentiate into cell types from the three germ layers in vitro.
