Histology and ICRS score of the rabbit osteoarthritis model after 12 weeks of experiments (). (a) Representative image of histology of the cartilage in normal saline control and HUCMSC+HA-treated knees. . (b) The normal saline control joints show a significantly lower ICRS histological score than the joints which receive HUCMSC+HA therapy (, ).
