Developing a non-toxic approach to bone-crushing cancers
When cancer spreads to the bone the results can be devastating Battling cancer is always a balancing act. The methods we use – surgery, chemotherapy and radiation - can help remove the tumors but they often come at a price to the patient. In cases where the cancer has spread to the bone the treatments … Continue reading Developing a non-toxic approach to bone-crushing cancers
From organs to muscle tissue: how stem cells are being used in 3D
A Sunday Afternoon on the Island of La Grande Jatte by Georges-Pierre Seurat When most people think of stem cells, they might conjure up an image of small dots under a microscope. It is hard to imagine these small specs being applied to three-dimensional structures. But like a pointillism painting, such as A Sunday Afternoon … Continue reading From organs to muscle tissue: how stem cells are being used in 3D
Mechanical forces are key to recovery after blood cancer treatment
Mesenchymal stem cells grown on a surface with specialized mechanical properties. Image courtesy of Krystyn Van Vliet at MIT. Blood cancers like leukemia and lymphoma will account for about 10% of all new cancer cases this year. Doctors often treat these diseases with irradiation, which kills the patient’s bone marrow — the source of blood … Continue reading Mechanical forces are key to recovery after blood cancer treatment
A stepping stone for bringing stem cell therapy to patients with ALS
Imagine being told that you have a condition that gradually causes you to lose the ability to control your body movements, from picking up a pencil to walking to even breathing. Such is the reality for the nearly 6,000 people who are diagnosed with amyotrophic lateral sclerosis (ALS) every year, in the United States alone. … Continue reading A stepping stone for bringing stem cell therapy to patients with ALS
Starving stem cells of oxygen can help build stronger bones
We usually think that starving something of oxygen is going to make it weaker and maybe even kill it. But a new study by J. Kent Leach at UC Davis shows that instead of weakening bone defects, depriving them of oxygen might help boost their ability to create new bone or repair existing bone. Leach … Continue reading Starving stem cells of oxygen can help build stronger bones
Lights, Camera, Stem Cells! How photo-responsive hydrogels can improve stem cell therapies
These days, going to the movie theater is like riding the wildest rollercoaster at your local theme park. It can be an IMAX 3D, surround sound, vibrating seat experience that makes you feel like you’re living the actual movie. As the entertainment industry evolves towards more intense, realistic cinematic experiences, scientists are following a similar … Continue reading Lights, Camera, Stem Cells! How photo-responsive hydrogels can improve stem cell therapies
License to heal: UC Davis deal looks to advance stem cell treatment for bone loss and arthritis
There are many challenges in taking even the most promising stem cell treatment and turning it into a commercial product approved by the Food and Drug Administration (FDA). One of the biggest is expertise. The scientists who develop the therapy may be brilliant in the lab but have little experience or expertise in successfully getting … Continue reading License to heal: UC Davis deal looks to advance stem cell treatment for bone loss and arthritis
Pregnant women’s stem cells could help battle brittle bone diseases like osteoporosis
Sometimes I wonder how a scientist ever came up with an idea for a potential treatment. Case in point is a study in the journal Scientific Reports, where researchers use stem cells from the amniotic fluid of a pregnant woman to cure osteoporosis in mice! What researcher, seeing a pregnant woman, thought to her or … Continue reading Pregnant women’s stem cells could help battle brittle bone diseases like osteoporosis
