  1. Indicated source is significantly different from both other sources at least at aP<0.001, bP<0.01, cP<0.05. dOnly significantly different from peripheral blood (PB). Data are presented as average ± standard deviation (n = 6, except for umbilical cord matrix (UCM), n = 2). UCB, umbilical cord blood.
