  • SC-islets are utilized in disease modeling through genetic modification, chemical treatments, or patient-derived stem cell differentiation.
  • Current SC-islet transplantation faces challenges due to immunosuppression side effects, limiting therapeutic efficacy.

Purpose of the Study:

  • To review recent advancements in utilizing SC-islets for understanding diabetes pathologies.
  • To explore the therapeutic potential of SC-islets as a cell therapy for diabetes.
  • To discuss strategies for overcoming transplantation barriers for SC-islet therapy.

Main Methods:

  • Review of recent scientific literature on SC-islet applications.
  • Analysis of methods for diabetes modeling using SC-islets.

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

EPS and iPS Cells in Disease Research

Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...
