Figure 4From: Restoration versus reconstruction: cellular mechanisms of skin, nerve and muscle regeneration compared Kinetics of skeletal muscle regeneration following focal injury in mouse. Hematoxilin and eosin staining (H&E) of murine Tibialis anterior muscle (only a portion of the muscle is shown) subjected to freezing by applying a liquid nitrogen-cooled steel forceps to the surface (facing right in the picture) of the muscle for 10Â seconds. The muscle was collected and analyzed 3, 6, 8 and 10Â days following injury (from left to right). The inset shows a higher magnification image of regenerating fibers 8Â days after injury: hallmarks of regenerating fibers include reduced fiber size and centrally located nuclei.Back to article page
