We found that after two weeks in culture, more than 90% of cells derived from tumors with high levels of Gata3 (e.g., B tumor cell line) belonged to a CD24+CD29low population in two different culture media whereas cells derived from tumors with low levels of Gata3 (e.g., C tumor cell line) contained a CD24-CD29low population in FBS high medium (MEC medium) or a mixture of CD24-CD29low and CD24+CD29low populations in FBS low medium (MM+ medium). This evidence concerns the gene GATA3 and neoplasm.
