Ligustrazine Inhibits Cartilage Endplate Hypertrophy via Suppression of TGF-β1

Figure 3

Effects of LIG on CEP hypertrophy of the lumbar spine in bipedal rats. (a, b) Representative images of Safranin O fast green staining of L4 section showed a significant increase in OFT at the marginal disc of bipedal rats. LIG partially reduced the noncartilaginous outgrowth. (c–e) The expression of the three osteogenesis-related markers: (c) Col1a2, (d) ALP, (e) Runx2 in the Sham, Veh, and LIG groups. Each column represents the mean ± SE, versus Sham, and versus Veh.
