Biochemical analysis of the kidney in each group 14 days postoperatively. Levels of serum creatinine (SCr) and blood urea nitrogen (BUN) detected. hucMSC-CM inhibited the increase of SCr and BUN in UUO-induced rats. Values presented as mean ± SD. UUO group compared with Sham, Control, and hucMSC-CM groups. Values statistically significant at: *P < 0.05, Sham and Control groups compared with UUO and hucMSC-CM groups; #P < 0.05. CM conditioned medium, hucMSC human umbilical cord-derived mesenchymal stem cell, UUO unilateral ureteral obstruction
