Correlations of B cells with highly-differentiated CD8+CD28− T cells (a), immunosenescent/replicative senescent CD8+CD57+ (b), and highly-differentiated, replicative senescent CD8+CD28−CD57+ T cells in the human BM. B cells are defined as CD19+ lymphocytes, T cells are defined as CD3+ lymphocytes. Correlation coefficients (rp) and significances were calculated according to Pearson with correction for age
