T cell progenitors derived from induced pluripotent stem cells fail to effectively differentiate into CD4+ helper cells. Here we describe a key role for the withdrawal of Notch ligand during the final step of stimulation through the T cell receptor to prompt T cell maturation allowing access to the CD4 lineage in iPSC T cells (iT cells). These CD4+ iT cells produce signature CD4 cytokines and express a transcriptional signature similar to human blood CD4 T cells. We believe this is a key step towards iT cell therapies incorporating both helper and cytotoxic iT cells.</description><dates><publication>2026/09/16</publication></dates><accession>GSE279734</accession><cross_references><GSM>GSM8579404</GSM><GSM>GSM8579402</GSM><GSM>GSM8579403</GSM><GPL>11154</GPL><GSE>279734</GSE><taxon>Homo sapiens</taxon><PMID>[42660120]</PMID></cross_references></HashMap>
