Figure 5From: Inhibition of interleukin-1beta-stimulated dedifferentiation of chondrocytes via controlled release of CrmA from hyaluronic acid-chitosan microspheresWestern blot analyses for type II collagen, aggrecan I, collagen and IL-1beta. Type II collagen and aggrecan expression was substantially restored by HA-CS-CrmA microspheres. However, collagen I and IL-1β were decreased in HA-CS-CrmA group and CS- CrmA group compared with the OA group.Back to article page
