Generating pancreatic beta cells from pluripotent stem cells for diabetes cell therapy or drug development

Tech ID: T-019409

Technology Description:

Researchers in Prof. Jeffrey Millman’s laboratory have developed multiple techniques for enhancing the differentiation, maturation and function of glucose-responsive, insulin-producing SC-beta cells (pancreatic beta cells made from human pluripotent stem cells). Downstream, these SC-beta cells could potentially be used for cell therapy to treat diabetes or as a disease model system for research and high throughput drug screening.

These methods leverage both developmental biology and bioengineering techniques to discover and recapitulate conditions during normal human development. For example, certain culture techniques and reagents can be used to scale production, freeze cells (for shipping and quality control) or promote function or maturation at specific stages of cell development. Furthermore, tools for functional studies of SC-beta cells have revealed microenvironmental cues and stress responses that can influence cell fate or improve cell function. Collectively, these protocols and discoveries represent the most advanced system for affordable, scalable and reproducible generation SC-beta cells. The cells provide a unique window to study Type 1, Type 2 or monogenic forms of diabetes. The cells also offer a potential therapy to help the millions of people who currently require insulin injections to control their diabetes.

The state-of-the-art protocol generates glucose-responsive SC-beta cells from embryonic and induced human pluripotent stem cells.

Stage of Research:

The Millman lab has successfully used their protocols to convert human stem cells into insulin-producing cells with secretion dynamics approaching that of primary islets; transplanted those SC-beta cells into diabetic model mice; and demonstrated that they can control blood sugar and functionally cure diabetes for 9 months (Nature Biotechnology). They continue to employ a variety of techniques to identify novel signaling pathways regulating beta cell differentiation and functional maturation with a goal to refine and improve the process for better scalability and cell function.
