Scientists in Sweden have established a reliable method for generating insulin-producing cells from human stem cells as a potential cure for type 1 diabetes.
The findings, published in Stem Cell Reports, indicate that these laboratory-generated cells can effectively manage blood sugar levels in tests and even reverse diabetes in mice.
A professor at the Department of Molecular Medicine and Surgery at Karolinska Institutet, Per-Olof Berggren has stated, “We have developed a method that reliably produces high-quality insulin-producing cells from multiple human stem cell lines. This opens up opportunities for future patient-specific cell therapies, which could reduce immune rejection.”
The innovative method increases the production of these cells, resulting in insulin-producing cells that are both more advanced and functional compared to those generated by previous methods.
In laboratory tests, the cells demonstrated insulin release and exhibited a robust response to glucose concentrations.
Upon transplantation into diabetic mice, the cells gradually restored the animals’ capacity to regulate blood sugar levels.
The researchers implanted the cells in the anterior chamber of the eye, enabling them to monitor the development and functionality of the cells over time.
Scientists uncover new technique for type 1 diabetes
Stem cell treatments for type 1 diabetes are currently undergoing clinical trials.
However, they face multiple obstacles. A major concern is that stem cells frequently differentiate into a combination of beneficial and undesirable cell types, which can increase risks.
Additionally, lab-cultivated insulin cells often lack sufficient maturity to adequately respond to glucose.
To tackle these issues, the researchers enhanced the culture technique and allowed the cells to develop into natural three-dimensional clusters.
This approach diminished the presence of unwanted cell types and improved the cells’ responsiveness to glucose.
