Summary:The present disclosure addresses cell type heterogeneity during differentiation of human pluripotent stem cells into islet cells by shifting cell identity from alpha cells to beta cells. More specially, the present disclosure provides a clonal human pluripotent stem cell line that broadly expresses the gene NKX6.1 across cells at the pancreatic progenitor cell stage of in vitro differentiation, which yields fewer alpha cells and more beta cells during directed differentiation to islet cells. The present disclosure further provides a method of improving the yield of insulin-producing cells produced from pluripotent stem cells for transplantation into patients with diabetes. La présente divulgation aborde l'hétérogénéité de type de cellule pendant la différenciation de cellules souches pluripotentes humaines en cellules d'îlot par décalage d'identité de cellule de cellules alpha à des cellules bêta. Plus particulièrement, la présente divulgation concerne une lignée de cellules souches pluripotentes humaines clonales qui exprime largement le gène NKX6.1 à travers des cellules au stade de cellule progénitrice pancréatique de différenciation in vitro, ce qui donne moins de cellules alpha et plus de cellules bêta pendant la différenciation dirigée vers des cellules d'îlot. La présente divulgation concerne en outre un procédé d'amélioration du rendement de cellules productrices d'insuline produites à partir de cellules souches pluripotentes pour une transplantation chez des patients atteints de diabète.
