The discovery helps to more efficiently at less cost make insulin-producing beta cells from human stem cells.
The researchers discovered that the same signal -- the so-called epidermal growth factor (EGF) pathway -- controls both the formation of pipes and beta cells through polarity changes.
So there is always interest in any process that might generate new beta cells to replace those lost in Type 1 diabetes.
By: Egypt Today staff CAIRO - 5 June 2017: Scientific research supervised by American researchers show that quick sport exercises improve the function of beta cells in adults who suffer from diabetes type 2.
Conclusion: Citrullus colocynthis aqueous seed extract stabilised animal body weight and ameliorated hyperglycaemia in a dose-and time-dependent manner which was attributable to regenerative effect on beta cells and intra-islet vasculature.
The goal of this collaboration is to develop a beta cell replacement therapy based on functional beta cells derived from human stem cells.

In a study published in the journal Cell last month, mice with simulated type 1 and type 2 diabetes that were subjected to a fasting-like diet and then restored to a normal diet experienced renewed production of beta cells in the pancreas, which restored normal insulin production and resulted in more stable blood glucose levels.
Editor's Note: As potential mechanisms, the authors note that zinc is needed for insulin's action, for carbohydrate metabolism, to moderate inflammatory cytokine levels that can destroy beta cells, for preventing human islet amyloid polypeptides from aggregating to form amyloid fibers that have a toxic effect on beta cells, to reduce oxidative stress and for other protective functions.
Transgenic expression of dominant-negative Fas-associated death domain protein in beta cells protects against Fas ligand- induced apoptosis and reduces spontaneous diabetes in nonobese diabetic mice.
In autoimmune diseases, it is thought that deficient Treg activity permits the T effector cells to attack the body's own beneficial cells, and in the case of T1D, insulin-producing pancreatic beta cells.
Scientists have previously shown that killer T-cells, a type of white blood cell that normally protects us from germs, play a major part in type 1 diabetes by destroying insulin producing cells, known as beta cells.
