MDSC frequencies among healthy adults. Blood samples were collected from 67 healthy subjects (30 males, 37 females) ages 20 to 93 in K2EDTA tubes. Quantitative results for CD45+, CD33 + CD11b + (total MDSC), M-MDSC (CD14+), PMN-MDSC (CD15+), MDSC counterparts (CD14−CD15−) from each subject are shown as individual symbols. No significant difference was found in total MDSC levels among subjects (both genders) 60 years and younger (N = 41) compared to those over the age of 60 (N = 26) (unpaired t test, p = 0.5, bottom right panel)
