Galicia-Silva, Mai Liu, Zihan Gao, Samuel D. Pollock, Juan R. Alvarez-Dominguez*, Jia Liu* INTRODUCTION: Human pluripotent stem cell–derived islets (SC-islets) hold promise for diabetes research and therapy but show functionally immature glucose responsiveness. Although several strategies promote maturation, SC-islets still fall short of the precision and dynamics of hormone secretion in primary islets. Whether this reflects poor coordination among α and β cells or intrinsic heterogeneity is unknown. Progress requires tools to decipher how individual cell functions specialize and synchronize within intact three-dimensional (3D) tissue over time. cells showed the opposite pattern, which is consistent with insulin release. …
