Other researchers reported an increase of cEPCs levels (CD34+CD133+KDR+) after two months of glycaemic control in newly-diagnosed diabetic patients, T1DM patients and diabetic patients without complications, while the levels did not change in patients with pre-existing DM, T2DM patients, and diabetic patients with DVC [104]. This evidence concerns the gene KDR and type 1 diabetes mellitus.
