Blood glucose and urinary albumin excretion rate after transplantation in diabetic rats. At different timepoints, the levels of blood glucose, urinary volume, urinary albumin and urinary protein were evaluated. a Effects of progenitor cells on glycemic levels in diabetic rats; b effects of progenitor cells on urinary volume in diabetic rats; c effects of progenitor cells on urinary protein levels in diabetic rats; d effects of progenitor cells on urinary albumin levels in diabetic rats. Control normal rats, Diabetes DN rats treated with saline, Progenitors DN rats after transplantation, Insulin DN rats treated with insulin. *P < 0.01 progenitor cell group versus diabetic group
