Kinetic analysis of G-CSFR mRNA expression in CD3+ T cells at single-cell level following G-CSF stimulation in vitro. Direct stimulation of T cells (purity > 98%) compared with stimulation of PBMCs with G-CSF in vitro did not show a significant difference in the frequency of T cells expressing G-CSFR mRNA (P = .28, chi-square test). Repetitive stimulation of T cells every 24 hours led to sustained G-CSFR expression. All of the analyzed single cells expressed TCR-α chain mRNA. — indicates not determined
