In a study done at the Kunming Medical University showed that MSCs ameliorate the renal function and extend survival in diabetic rats, regulate the production of lipoxin 4 (LXA4) and ALX/FPR2 (the receptor of LXA4) in kidney tissue of DN, protect renal function and inhibit fibrosis (26). The gene discussed is FPR2; the disease is liver dysplastic nodule.
