Pulsed electromagnetic field (PEMF) promotes collagen fibre deposition associated with increased myofibroblast population in the early healing phase of diabetic wound.

The present study evaluated the effects of PEMF on collagen fibre deposition, collagen fibril alignment and collagen fibre orientation. The potential relationships between collagen fibre deposition and myofibroblast population in diabetic wound healing were also examined. Forty young male streptozotocin-induced diabetic Sprague-Dawley rats were randomly assigned to PEMF group or control group.
