a: Adipocytes recruited after Ad5F35-BMP2 and stained with Bodipy 493/502. b: Bodipy staining of muscle injected with cells carrying an empty vector, Ad5F35-null. c: Brown (yellow arrows) and white (white arrows) adipocytes after staining with Mitotracker. d: Mitotracker staining of muscle injected with cells carrying an empty vector. Tissues in a and c were harvested 24 hours after injection of BMP2-producing cells, and those in b and d, 24 hours after injection of cells transduced with empty vector.
