From: Effect of sIL-13Rα2-Fc on the progression of rat tail intervertebral disc degeneration
Hematoxylin and eosin (H&E) staining showing the histological effects of sIL-13Rα2-Fc intervention on intervertebral disc tissue in rats. a Histological assessment of annulus fibrosus in healthy and injured intervertebral discs (× 40). Compared with to the model group, sIL-13Rα2-Fc significantly slowed intervertebral disc degeneration in rats, which was characterized by uniform arrangement of the AF, reduction of the rupture site. b Histological assessment of nucleus pulposus in healthy and injured intervertebral discs (× 40). Compared with to the model group, sIL-13Rα2-Fc significantly slowed intervertebral disc degeneration in rats, which was characterized by increased number of NP cells
