Our Innovation

A method of generating insulin producing cells, by dedifferentiating induced pluripotent stem cells (iPSCs). The beta cell-derived iPSCs (BiPSCs) maintained open chromatin structure at key beta-cell genes, together with a unique DNA methylation signature that distinguishes them from other PSCs.

BiPSCs also demonstrated an increased ability to differentiate into insulin-producing cells both in vitro and in vivo, compared with ESCs and isogenic non-beta iPSCs.

 

  • This method demonstrates an advantageous potential for cell replacement therapy for developing advanced treatments for diabetes.

Technology

Human induced pluripotent stem cells (HiPSCs) appear to be highly similar to human embryonic stem cells (HESCs). The researchers demonstrate the generation of iPSC lines from human pancreatic islet beta cells using two genetic lineage-tracing systems.  These reprogrammed cells acquired markers of pluripotent cells and differentiated into the three embryonic germ layers.
