Regenerative medicine took a step forward on Monday with the announcement of the creation of the first disease-specific line of embryonic stem cells made with a patient’s own DNA (…)
“This is a really important step forward in our quest to develop healthy, patient-specific stem cells that can be used to replace cells that are diseased or dead,” said Susan Solomon, chief executive officer of NYSCF, which she co-founded in 2005 partly to search for a cure for her son’s diabetes.
Stem cells could one day be used to treat not only diabetes but also other diseases, such as Parkinson’s and
A DRUG said to cure diabetes could mean that sufferers will no longer need to take daily insulin injections.
The treatment uses stem cells made from human bone marrow and has been tested on patients suffering from Type 1 diabetes – which affects about 900,000 people in Britain.
Diabetes causes the immune system to attack the pancreas, the organ that makes insulin, which then controls blood-sugar levels.
Sufferers must take insulin injections to stay alive because if blood-sugar levels are allowed to rise too high or get too low, they could fall into a coma and die.

Inability to control autoimmunity is the primary barrier to developing a cure for type 1 diabetes (T1D). Evidence that human cord blood-derived multipotent stem cells (CB-SCs) can control autoimmune responses by altering regulatory T cells (Tregs) and human islet beta cell-specific T cell clones offers promise for a new approach to overcome the autoimmunity underlying T1D.
We developed a procedure for Stem Cell Educator therapy in which a patient’s blood is circulated through a closed-loop system that separate lymphocytes from the whole blood and briefly co-cultures them with adherent CB-SCs before returning them to the patient’s circulation. In an open-label,
Alan Lewis of the Juvenile Diabetes Research Foundation distinguishes type 1 and type 2 diabetes, and continues to explain how stem cells are being used today to develop new treatments for type 1 diabetes (a.k.a. juvenile diabetes). Human embryonic stem cells (hESC) are being differentiated to the beta (insulin producing) cells that type 1 diabetics lack, and are being transplanted , in animal models. Since type 1 diabetes is an auto-immune disease, the transplanted cells must be protect from destruction by the immune system. Currently, researchers are working towards that goal with encapsulating technologies and a “gentle” immuno-modulation. In

Researchers funded by the National Institutes of Health have converted stem cells from the human endometrium into insulin-producing cells and transplanted them into mice to control the animals’ diabetes.
The endometrium, or uterine lining, is a source of adult stem cells. Normally, these cells generate uterine tissue each month as part of the menstrual cycle. Like other stem cells, however, they can divide to form other kinds of cells.
The study’s findings suggest the possibility that endometrial stem cells could be used to develop insulin-producing islet cells. These islet cells could then be used to advance the study
