Summary
Human pluripotent stem cells (hPSCs) offer a promising diabetes cure via stem-cell-derived islets (SC-islets). Addressing safety concerns from residual cells is key for clinical application.
Area of Science:
- Regenerative Medicine
- Developmental Biology
- Endocrinology
Background:
- Human pluripotent stem cells (hPSCs) are utilized for in vitro islet cell differentiation, aiming to cure diabetes.
- Stem-cell-derived islets (SC-islets) show potential in preclinical and early clinical studies for diabetes reversal.
- A primary safety concern for SC-islets involves off-target cell growth from residual contaminating cells.
Purpose of the Study:
- To review endocrine and non-endocrine cell populations during beta cell differentiation and post-transplantation.
- To discuss current strategies for enriching endocrine cell populations and eliminating off-target cells.
- To outline essential quality control and release criteria for ensuring SC-islet product safety before transplantation.
Main Methods:
- Review of scientific literature on stem cell differentiation and islet biology.
- Analysis of cell populations arising during beta cell differentiation.
- Evaluation of methods for cell enrichment and removal of contaminants.
- Discussion of quality control measures for cell-based therapies.
Main Results:
- Identification of diverse endocrine and non-endocrine cell types during beta cell differentiation.
- Description of various approaches to enhance the purity of endocrine cell populations.
- Highlighting the necessity of rigorous testing to ensure safety and efficacy.
- Summarizing challenges and advancements in SC-islet development.
Conclusions:
- SC-islets hold significant promise for diabetes treatment, but safety remains a critical hurdle.
- Effective methods for purifying SC-islets and stringent quality control are essential for clinical translation.
- Further research into cell population dynamics and removal of off-target cells will advance the therapeutic potential of SC-islets.

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.

After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
