Title:
ISLET-LIKE ORGANOID EXPRESSING MONSTIM1 IN WHICH INSULIN SECRETION IS REGULATED BY OPTICAL STIMULATION
Document Type and Number:
WIPO Patent Application WO/2023/101369
Kind Code:
A1
Abstract:
The present invention relates to an islet-like organoid in which insulin secretion can be optically regulated by differentiating, into pancreatic islets, human pluripotent stem cells (monSTIM1-hPSC) obtained by knocking-in monSTIM1, which is an inducer of Ca2+ concentration increase (Ca2+ transient), into the AAVS1 locus of the stem cells. Since it has been confirmed in vitro and in the body of a diabetic mouse model that the islet-like organoid of the present invention can secrete insulin through an intracellular calcium influx increased by light irradiation, the islet-like organoid can be effectively used in the treatment of diabetic patients.
