Immunofluorescence staining of α-SMA in the renal mesenchyme and quantification revealed the induction of interstitial fibrosis after unilateral ureteral obstruction compared with the sham group. However, GDNF-AMSCs suppressed fibrotic expressions and increased PTCs density (*P < 0.05, **P < 0.01, ***P < 0.001)
