2003; Jenkins et al. 2009). Diabetes is associated with reduced mobilization of CAC populations (Fadini et al. 2013) and CD34+ and CD34+/KDR+ CAC have been negatively related to fasting and postchallenge glucose levels (Fadini et al. 2007). CFU‐CAC number, CAC eNOS phosphorylation (Ser1177), and NO in CAC culture media was reduced when cells were incubated in 25 mmol/L glucose compared with 5 mmol/L (Chen et al. 2007). Here, CD34 is linked to diabetes mellitus.
