Immunohistochemistry of type II collagen and aggrecan of the cartilage after 12 weeks of experiments. (a) Representative image of type II collagen in the cartilage of normal cartilage (negative control), normal saline control, and HUCMSC+HA-treated knee. . (b) The HUCMSC+HA-treated joints show no significantly higher content of type II collagen than the normal saline control joints (). (c) Representative image of aggrecan in the cartilage of normal cartilage (negative control), normal saline control, and treated knee. . (d) The HUCMSC+HA-treated joints show no significantly higher content of aggrecan than the normal saline control joints (). No statistical differences are noted between both groups. Ctrl: control.
