Cultured cells were transduced with a lentiviral vector expressing a marker gene, to simulate a gene therapy context. CD34+ cells from donor 1 were analyzed before culture, on day 4 and on day 8 of expansion. For donor 2, in addition to the CD34+ bulk expansion culture, part of the CD34+ cells were FACS-sorted into subpopulations enriched in primitive HSPC (CD34+CD38-), committed granulocyte-monocyte progenitors (GMP) or megakaryocyte-erythrocyte progenitors (MEP), and subsequently expanded for 7 days.","dates":{"publication":"2026/06/10"},"accession":"GSE292606","cross_references":{"GSM":["GSM8862367","GSM8862366","GSM8862372","GSM8862371","GSM8862370","GSM8862369","GSM8862368"],"GPL":["24676"],"GSE":["292606"],"taxon":["Homo sapiens"]}}
