context connective tissue cells include fibroblasts, chondrocytes, adipocyte, and osteocytes. these cells are specialized for the secretion of collagenous extracellular matrix and are responsible for the architectural framework of the human body. evidence acquisition connective tissue cells play a central role in supporting as well as repairing tissues and organs. fibroblast cell therapy could ...

BACKGROUND Patients with recessive dystrophic epidermolysis bullosa (RDEB) have deficiencies of collagen type VII and have elevated levels of fibroblast collagenase, and a greatly increased risk of cutaneous squamous cell carcinoma. Patients with other genetic blistering disorders do not have elevated collagenase or an increased risk of squamous cell carcinoma, despite chronic wounding. The con...

IMPORTANCE Epidermolysis bullosa (EB) pruriginosa is a rare variant of dystrophic EB. It may manifest late in life and is characterized by intense pruritus, resulting in a phenotype resembling acquired inflammatory dermatoses. Dermatopathology textbooks include hereditary forms of EB among the "cell-poor" list of subepidermal blistering disorders. OBSERVATIONS We report a case of dominant dys...

Fig 1. Squamous cell carcinoma identified after multiple biopsy specimens of poorly healing area over left E pidermolysis bullosa (EB) consists of a heterogeneous group of autosomal dominant or recessive disorders, characterized by epithelial fragility. In dystrophic EB, patients have a genetic defect in the gene encoding collagen VII, COL7A1. Generalized severe recessive dystrophic EB (RDEB) i...

Dystrophic epidermolysis bullosa (DEB) is a severe skin fragility disorder associated with trauma-induced blistering, progressive soft tissue scarring, and increased risk of skin cancer. DEB is caused by mutations in the COL7A1 gene which result in reduced, truncated, or absent type VII collagen, and anchoring fibrils at the dermal-epidermal junction (DEJ). Because no topical wound-healing agen...
