Insulin-producing cells found in a variety of tissues in diabetes

18.02.2004


Cells that produce insulin have been unexpectedly found in the fat, liver and bone marrow of diabetic mice, said researchers at Baylor College of Medicine (BCM) in a report that appeared today in the Proceedings of the National Academy of Sciences.



"In fact, the appearance of insulin-producing cells occurs in both type 1 (juvenile) and type 2 (adult-onset) diabetic mice," said Dr. Lawrence Chan, chief of the BCM endocrinology section and professor in the department of medicine and molecular and cellular biology.

"The common denominator in all the animals is high blood sugar, not insulin-deficiency," he said. "High blood sugar causes these cells to produce insulin."


The numbers of cells and the amount of insulin produced are both very small and do not seem to ameliorate the animals’ disease, said Chan.

He found that the source of the insulin-producing cells is the bone marrow, which had been identified as the origin of many different kinds of tissues in recent years. He and his colleagues were surprised that only a brief three-day period of high blood glucose was sufficient to nudge the cells outside the pancreas to produce insulin.

If this inherent property of cells can be harnessed and augmented, Chan speculates, scientists could it to generate insulin-producing cells from other tissues for the treatment of diabetes. If the production of insulin by cells outside the pancreas affects the immune system, which goes awry in people predisposed to type 1 diabetes, it could affect the course of the disease.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
