(a) Macroscopic appearance of meniscus tissue; (b) Macroscopic appearance of tibial plateau, n = 6; (c)Histological analysis of meniscus regeneration through H&E staining; (d)Safranin O/Fast Green staining; (e)Collagen II and (f)Collagen I staining after two months of treatment with mECM or Cowihide collagen, n = 6. Blue arrows indicate fibrotic tissue; Yellow five-pointed stars indicate blood vessels.
