From: Effect of sIL-13Rα2-Fc on the progression of rat tail intervertebral disc degeneration
Masson staining showing the effects of sIL-13Rα2-Fc intervention on intervertebral disc degeneration in rats. There were varying degrees of damage in the intervertebral disc tissue in the model group, specifically presenting as AF rupture, disorganized arrangement, reduced number of NP cells, and a blurred boundary between the AF and the NP. The improvement of this damage was more obvious, with increasing of the dose of sIL-13Rα2-Fc intervention. AF: black arrow, NP: write arrow
