Isolation and Culture of Epidermolysis Bullosa Cells and Organotypic Skin Models.

Isolation and culture of keratinocytes from patients with different types of epidermolysis bullosa are sometimes challenging, because of the inherent adhesion defects of these cells. We routinely employ a well-established protocol for in vitro culture of these cells from small skin samples remaining left after diagnostic procedures are performed. Keratinocytes and fibroblast can be used for downstream expression and functional studies or for construction of in vitro organotypic cocultures. These cells maintain main common characteristics of spreading, adhesion, migration, and survival, which depend on the underlying molecular defect.
