Yield of PBMCs and % positive CD2 and CD56 cells from SMK, MSC and NTC. Yield of total PBMCs from SMK, MSC and NTC cohorts (40 subjects/cohort) are shown on the top panel. % CD2 positive cells from SMK, MSC and NTC cohorts are shown in the middle panel. % CD56 positive cells from SMK, MSC and NTC cohorts are shown in the bottom panel. The Tukey–Krammer honest significant difference test (α = 0.05) was used to compare the mean values among cohorts
