Fig. 1From: Histological and biochemical evaluation of plasma rich in growth factors treatment for grade II muscle injuries in sheepRepresentative histological sections stained with HE from grade II muscle injury in sheep, treated with PRGF (a, c, e) or Saline solution (b, d, f); at 1 (a, b), 2 (c, d) and 4 (e, f) weeks after the surgical muscle damage. Black arrows point at inflammatory cells infiltration; red arrows point at Centrally Nucleated Fibers (CNF). Muscles treated with PRGF showed statistically significant less inflammatory cells infiltration, and higher percentage of CNF than those muscles injected with Saline solution along the studyBack to article page
