Fibroblast senescence in pressure ulcers

Abstract excerpt

Pressure ulcers appear as localized chronic wounds in the middle of normal functioning skin. This study focuses on pressure ulcer fibroblasts cultured from the ulcer bed, ulcer margin, and normal, nonulcerated skin adjacent to the wound. From these areas we show that pressure ulcer fibroblasts become prematurely senescent. Verification of senescence was based on failure of cell populations to undergo a 0.5...
