Notably, both, the number of CD31+ and CD34+ cells, was significantly lower in the tumor-adjacent adipose tissue of overweight/obese patients: While CD31+ cells were reduced by 43% (p = 0.018), CD34+ cells were reduced by 64% (p = 0.045) (Table 3 and Figure 2). The gene discussed is PECAM1; the disease is neoplasm.
