SELL and neoplasm: Similarly, OVA-specific CD4+ iTSCM cells also survived in the sentinel lymph nodes and suppressed E.G7-OVA cell growth more efficiently than CD4+ TEM and TCM cells, iTCM cells, and CD62L+ cells, although CD4+ iTSCM cells showed weaker tumour suppressing effects than CD8+ iTSCM cells did (Supplementary Fig. 12b,c).
