Graphs illustrate marked improvement in renal system after umbilical cord mesenchymal stem cell transplantation. (A) British Isles Lupus Assessment Group (BILAG) score improved over time. Twenty-four hours after umbilical cord mesenchymal stem cell transplantation (MSCT), declines were observed in proteinuria (B), serum creatinine (C) and blood urea nitrogen (BUN) (D). BILAG scores for the hematopoietic (E) and cutaneous (F) systems were ameliorated after MSCT. *P < 0.05 versus before MSCT. **P < 0.01 versus before MSCT. Error bars mean SD values.
