Human Pluripotent Stem Cells Go Diabetic: A Glimpse on Monogenic Variants

Area of Science:

• Endocrinology
• Genetics
• Stem Cell Biology

Background:

• Diabetes mellitus affects over 350 million people globally, with Type 1 (T1D) and Type 2 (T2D) being the most prevalent forms.
• A significant genetic component underlies diabetes, with 1-2% of cases attributed to monogenic mutations.
• Understanding the genetic basis of monogenic diabetes is crucial for elucidating beta-cell function, pancreatic development, and advancing cell replacement therapies.

Purpose of the Study:

• To review the current applications of pluripotent stem cells in studying monogenic diabetes.
• To highlight the potential of stem cell-derived pancreatic models for understanding gene function in diabetes pathogenesis.
• To discuss the utility of these models for evaluating novel therapeutic strategies.

Main Methods:

• Utilizing pluripotent stem cells differentiated into pancreatic lineages.
• Employing these stem cell-derived models to investigate the functional impact of identified monogenic diabetes mutations.
• Reviewing existing literature on stem cell applications in monogenic diabetes research.

Main Results:

• Pluripotent stem cell platforms enable the study of specific gene mutations' effects on beta-cell development and function.
• These models facilitate the characterization of pathophysiological mechanisms underlying monogenic diabetes variants.
• The platform aids in assessing the efficacy of cell replacement therapies for monogenic forms of diabetes.

Conclusions:

• Pluripotent stem cell differentiation provides a powerful tool for dissecting the genetic underpinnings of monogenic diabetes.
• This approach is vital for advancing our knowledge of beta-cell biology and developing targeted therapies.
• Stem cell-based research holds significant promise for personalized medicine in monogenic diabetes.
