Blocking differentiation is enough to give cells ‘stemness’

October 23, 2015 by · Leave a Comment 

Though immune therapy and regenerative medicine are promising areas of research for future medical therapies, they are limited today by the difficulty of creating stem cells, and scientists around the world are searching for ways to create somatic stem cells in the easiest way possible. Now, a collaboration between the RIKEN Center for Integrative Medical Science (IMS) and other institutions in Japan and Europe have found that in immune cells, simply blocking a transcription factor that leads to differentiation is sufficient to keep cells in a multipotent stem cell-like state where they can continue to proliferate and can later differentiate into various cell types.

Researchers mimic viral infection in colon cancer stem cells

August 27, 2015 by · Leave a Comment 

Researchers targeting colorectal cancer stem cells – the root cause of disease, resistance to treatment and relapse – have discovered a mechanism to mimic a virus and potentially trigger an immune response to fight the cancer like an infection.

Study provides hope for some human stem cell therapies

August 21, 2015 by · Leave a Comment 

An international team of scientists headed by biologists at UC San Diego has discovered that an important class of stem cells known as human “induced pluripotent stem cells,” or iPSCs, which are derived from an individual’s own cells, can be differentiated into various types of functional cells with different fates of immune rejection.

Can stem cells cause and cure cancer?

August 13, 2015 by · Leave a Comment 

Simply put, cancer is caused by mutations to genes within a cell that lead to abnormal cell growth. Finding out what causes that genetic mutation has been the holy grail of medical science for decades. Researchers at the Texas A&M Health Science Center Institute of Biosciences and Technology believe they may have found one of the reasons why these genes mutate and it all has to do with how stem cells talk to each other.

NYSCF Global Stem Cell ArrayTM brings precision medicine one step closer to the clinic

August 3, 2015 by · Leave a Comment 

Scientists at The New York Stem Cell Foundation (NYSCF) Research Institute successfully designed a revolutionary, high-throughput, robotic platform that automates and standardizes the process of transforming patient samples into stem cells. This unique platform, the NYSCF Global Stem Cell ArrayTM, for the first time gives researchers the scale to look at diverse populations to better understand the underlying causes of disease and create new individually tailored treatments, enabling precision medicine in patient care.

New measurements reveal differences between stem cells for treating retinal degeneration

July 3, 2015 by · Leave a Comment 

By growing two types of stem cells in a “3-D culture” and measuring their ability to produce retinal cells, a team lead by St. Jude Children’s Research Hospital researchers has found one cell type to be better at producing retinal cells.

Factors released following stem cell transplantation therapeutically impact serious burns

June 25, 2015 by · Leave a Comment 

Cell transplantation researchers have successfully used bone marrow-derived mesenchymal stromal cells (MSCs) to treat a variety of diseases and conditions. Now, using injections of MSCs, a research team in Brazil has successfully treated laboratory rats modeled with severe burns. They found that the MSCs accelerated healing, enhanced local blood supply, affected the immune system in a positive way, secreted beneficial growth factors with anti-inflammatory properties, and ultimately provided higher survival rates than in control animals not treated with MSCs.

UTHealth research: Autologous stem cell therapy helpful in traumatic brain injury

June 8, 2015 by · Leave a Comment 

The use of cell therapy after traumatic brain injury (TBI) in children can reduce the amount of therapeutic interventions needed to treat the patient, as well as the amount of time the child spends in neurointensive care, according to research by The University of Texas Health Science Center at Houston (UTHealth) Medical School.

More power to the mitochondria: Cells’ energy plant also plays key role in stem cell development

April 30, 2015 by · Leave a Comment 

Researchers at NYU Langone Medical Center have discovered that mitochondria, the major energy source for most cells, also play an important role in stem cell development — a purpose notably distinct from the tiny organelle’s traditional job as the cell’s main source of the adenosine triphosphate (ATP) energy needed for routine cell metabolism.

U-M researchers find new gene involved in blood-forming stem cells

April 16, 2015 by · Leave a Comment 

Research led by the University of Michigan Life Sciences Institute has identified a gene critical to controlling the body’s ability to create blood cells and immune cells from blood-forming stem cells–known as hematopoietic stem cells.
