Comparison of characteristics of the activated NK cells. A Immunophenotyping of activated NK cells (n = 5). B Analysis of the quantitative gene expression differences of Perforin, IFN-γ, Granzyme A and B between IL-15 and IL-15/Hsp70-activated NK cells on the 21st day (n = 3). P < 0.01 was considered significant (*P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001 and **** P ≤ 0.0001). Data is demonstrated as mean ± SD
