Physiologic and metabolic parameters after 4 weeks treatment.

<p>STZ injection led to a significant stable increase of random blood glucose level (A) and body weight loss (B) in the diabetic rats compared to age-matched non-diabetic controls. *<i>p</i><0.05, body weight of normal rats control at day 28 <i>versus</i> other group rats; **<i>p</i><0.01. Both of the blood glucose concentration and body weights in diabetic rats were not affected by either treatment including VEGF or ADSCs or ADSCs-VEGF injection into the cavernous of DED rats.
