Histological observation of the MSC-encapsulated hybrids. (a) Photomicrographs showed Masson trichrome staining of the MSC-encapsulated hybrids treated with free swelling and compressive loading at magnitudes of 5%, 10%, and 20%. (b) The immunohistochemistry staining of the deposition of aggrecan in the MSC-encapsulated hybrids treated with free swelling and compressive loading at magnitudes of 5%, 10%, and 20%. White bar = 200 mm. Black bar = 50 mm. ().
