Adult mesenchymal stem cells, specifically adipose-derived stem cells have self-renewal and multiple differentiation potentials and have shown to be the ideal candidate for therapeutic applications in regenerative medicine, particularly in peripheral nerve regeneration. Adipose-derived stem cells are easily harvested, although they may show the effects of aging, hence their potential in nerve repair may be limited by cellular senescence or donor age. Cellular senescence is a complex process whereby stem cells grow old as consequence of intrinsic events (e.g., DNA damage) or environmental cues (e.g., stressful stimuli or diseases), which determine a permanent growth arrest. Prof. Magnaghi and his team from University of Milan in Italy reported some of the most important factors modulating the senescence process, which can influence adipose-derived stem cell morphology and function, and compromise their clinical application for peripheral nerve regenerative cell therapy. These findings, published in the Neural Regeneration Research (Vol. 9, No. 1, 2014).

CIUDAD DE MEXICO, 31 de juliode 2014 /PRNewswire/ -- La obesidad es un problema de salud que padecen muchsimas personas de nuestro pas. Se estima que en los prximos aos Mxico podra ocupar el 7 lugar de pases con diabetes, es decir, casi 12 millones de mexicanos padecindola, nios y adultos, 1 de cada 3 podra tener diabetes.

La diabetes es un desorden que resulta de la insuficiente produccin de insulina o resistencia a la insulina donde el cuerpo no puede utilizarla de manera eficiente. La insulina es la responsable de que las clulas absorban la glucosa (azcar) para obtener la energa que necesitan as como el hgado y las clulas grasas para almacenamiento. Si existe una deficiencia de insulina o resistencia entonces los niveles de glucosa (azcar) en la sangre llegan a ser anormalmente altos.

Ningn otro parmetro fsico del cuerpo humano est ms fuertemente ligado a una enfermedad que lo que la obesidad est con la diabetes tipo 2. Aquellas personas que padecen obesidad corren de 40 a 90 veces ms riesgo de tener diabetes comparada con aquellas con un peso normal. Adems parece ser que el riesgo de la diabetes se relaciona con el tiempo que se ha tenido obesidad as como el nivel de obesidad.

Anteriormente se crea que la diabetes tipo 2 es una sentencia de cadena perpetua crnica, una pendiente cuesta abajo; hasta que un estudio cientfico dirigido por Cambridge Weight Plan ha sido capaz de demostrar que la diabetes tipo 2 en realidad es reversible con una dieta muy baja en caloras basada en suplementos alimenticios y vegetales sin almidn, que induce al cuerpo a eliminar la grasa que est obstruyendo el pncreas e impidiendo que este produzca insulina.

Despus de una semana, los niveles de azcar haban vuelto a la normalidad. Despus de dos meses, la grasa en el pncreas de cada paciente haba regresado a los niveles normales y el pncreas produca insulina con normalidad.

Tres meses ms tarde, despus de volver a la alimentacin normal con asesora nutricional, 7 de los 11 pacientes permanecieron libres de diabetes tipo 2.

The Adult Stem Cell Technology Center, LLC Launches A Marketing Campaign To License Adult Stem Cell Biotechnologies

Posted: July 31, 2014 at 1:42 pm

Boston, MA (PRWEB) July 31, 2014

Bostons Adult Stem Cell Technology Center, LLC (ASCTC) finds itself flush with innovative adult stem cell biotechnologies. Currently the company holds seven recently issued patents and has three additional patent applications currently under examination by the U.S. Patent and Trademarks Office.

The patented inventions address two of the most vexing problems in adult stem cell biology research and regenerative medicine. Adult stem cells are difficult to identify; and they have been difficult to multiply to sufficient numbers to support regenerative medicine applications.

ASCTC has addressed the identity problem by developing patented biomarkers that are found exclusively on adult stem cells. The biomarkers are based on ASCTCs expertise in defining properties of adult stem cells that are not shared by any other normal cell types in the body. The patented biomarkers also identify some types of cancer stem cells. Therefore, they have applications in both stem cell medicine and cancer medicine.

ASCTCa success in developing procedures for producing adult stem cells in large numbers is due to the companys expertise in adult stem cell growth control. ASCTCs technology uses natural compounds found in the body to instruct adult stem cells to multiply in a controlled manner as during normal body growth.

The companys patented method for controlling adult stem cells to multiply without losing their stem cell properties has applications for many different types of adult stem cells. ASCTCs approved patents demonstrate the application of the method for production of human liver stem cells, hair follicle stem cells, and human pancreatic stem cells; but the technology has general application to adult stem cells found in many other types of organs and tissues.

In addition to the main focus on adult stem cell technologies, ASCTCs most recently issued patent applies its cell multiplication methods to produce induced pluripotent stem cells (iPSCs) without transferring exogenous genes. This gene-free single agent method should offer significant value to the many mushrooming companies that supply iPSCs and iPSC production reagents.

As a small start-up, ASCTC is employing a social media marketing strategy. In the past week, the company has launched patent licensing ads on LinkedIn, Vocus, and Facebook, as well increased its advertising references within its recently established Twitter presence.

It would be a shame for these technologies to lie dormant, just because our hands are full with other projects at the moment. James Sherley, director of ASCTC, relates that the companys two main business efforts require only a fraction of its available intellectual property. ASCTC is currently focused on bringing laboratory-scale production of human liver stem cells to manufacturing scales and developing a computer simulation assay for preclinical detection of drug candidates with intolerable toxicity due to adverse effects on adult stem cells.

Sherley adds, We already have a few companies that have expressed interest in licensing. But we could do a lot better at reaching others whose development efforts would benefit from ASCTCs unique technologies. Love to hear from ViaCyte!

Early stem cell transplant may cure "bubble boy" disease

Posted: July 31, 2014 at 1:42 pm

"Bubble boy" David Vetter lived in a protective environment designed by NASA engineers. He died of complications after receiving a bone marrow transplant in 1984, at the age of 12. Baylor College of Medicine Photo Archives

Babies born with so-called "bubble boy" disease can often be cured with a stem cell transplant, regardless of the donor -- but early treatment is critical, a new study finds.

Severe combined immunodeficiency (SCID), as the condition is medically known, actually refers to a group of rare genetic disorders that all but eliminate the immune system. That leaves children at high risk of severe infections.

The term "bubble boy" became popular after a Texas boy with SCID lived in a plastic bubble to ward off infections. The boy, David Vetter, died in 1984 at the age of 12, after an unsuccessful bone marrow transplant -- an attempt to give him a functioning immune system.

Immune disorder forced David Vetter to live in bubble - but breakthroughs from his story now enable similar kids to live free

In the best-case scenario, a child would get stem cells -- the blood-forming cells within bone marrow -- from a sibling who is a perfect match for certain immune-system genes.

But that's not always an option, partly because kids with SCID are often their parents' first child, said Dr. John Cunningham, director of hematopoietic stem cell transplantation at the University of Chicago Comer Children's Hospital. He was not involved in the study.

In those cases, doctors typically turn to a parent -- who is usually a "half" match, but whose stem cells can be purified to improve the odds of success. Sometimes, stem cells from an unrelated, genetically matched donor can be used.

The good news: Regardless of the donor, children with SCID can frequently be cured, according to the new findings. But early detection and treatment is vital.

Sugar mimics guide stem cells toward neural fate

Posted: July 30, 2014 at 2:54 pm

Embryonic stem cells can develop into a multitude of cells types. Researchers would like to understand how to channel that development into the specific types of mature cells that make up the organs and other structures of living organisms.

One key seems to be long chains of sugars that dangle from proteins on surfaces of cells.

Kamil Godula's group at the University of California, San Diego, has created synthetic molecules that can stand in for the natural sugars, but can be more easily manipulated to direct the process, they report in the Journal of the American Chemical Society.

A variety of growth factors influence the fate of embryonic stem cells. All bind to specific receptors on the surface of the cell, but many must also bind to these sugars to exert their influence.

The natural sugar structures are difficult to manage, so Godula's group strung small sugar fragments together to create synthetic versions. They used these 'glycopolymers' to figure out how specific growth factors recognize sugars on the surface of cells.

By tagging individual glycopolymers, they were able to identify sugar substructures with the greatest affinity for fibroblast growth factor 2, one of the growth factors involved in neural development.

To test their mimetic molecules in a living system, they slipped successful versions into the into membranes of mouse embryonic stem cells that lack the natural form of the sugar. Six days later, these cells transformed into 'neural rosettes,' precursors of many types of mature neural cells. Untreated cells didn't.

Godula's group is working on a number of similar molecular mimics to explore a variety of developmental pathways.
