Mouse pancreatic stem cells successfully differentiate into insulin producing cells

26.09.2012
In a study to investigate how transplanted islet cells can differentiate and mature into insulin-producing pancreatic cells, a team of Japanese researchers found that using a specific set of transcription factors (proteins that bind to specific DNA sequences) could be transduced into mouse pancreatic stem cells (mPSCs) using Sendai virus (SeV), a mouse influenza virus, as a carrier, or vector. The study is published in a recent issue of Cell Medicine [3(1)], now freely available on-line at: http://www.ingentaconnect.com/content/cog/cm.

"Diabetes is one of the most serious and prevalent metabolic diseases," said study co-author Dr. Hiroshi Yukawa, Department of Advanced Medicine in Biotechnology and Robotics, Nagoya University Graduate School of Medicine. "Islet cell transplantation has proven effective, however this strategy requires sufficient organ donors."

Given the shortage of donors, the researchers investigated factors that could impact on the expansion and differentiation of pancreatic stem cells (PSCs) into insulin-producing cells using combinations of varieties of transcription factors and the SeV mouse virus to carry the cells, thus increasing the number of functional islet cells available for transplantation.

SeV vectors, said the researchers, are superior to conventional virus vectors because "they do not go through a DNA phase" and can introduce foreign genes without toxicity into a variety of cell types.

The combination of transcription factors that produced the greatest impact on the differentiation of PSCs into insulin cells was Pdx-1 (Pancreatic and duodenal homeobox 1), NeuroD (neurogenic differentiation) and MafA (musculoaponeurotic fibrosarcoma oncogene A). "Our data suggest that the transduction of transcription factors using SeV vectors facilitates mPSCs differentiation into insulin producing cells and showed the possibility of regenerating B-cells by using transduced PSCs," concluded the researchers.

This research was among those studies presented at the 37th Annual Meeting of the Japan Society for Organ Preservation and Medical Biology (JSOPMB). Sixteen studies were published in this special issue of CELL MEDICINE. The theme of the issue is "Organ/Cell Transplantation and Regenerative Medicine."

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
