For biological processes, knowing when to slow down is as important as knowing when to step on the accelerator. Take for example muscle stem cells. In a healthy state, these cells mostly lay quiet and rarely divide but upon injury, they bolt into action by dividing and specializing into new muscle cells to help repair … Continue reading The life of a sleeping muscle stem cell is very busy

Clever technique uncovers role of stem cells in cartilage repair
Over 50 million adults in the U.S. are estimated to be affected by some form of arthritis, a very painful, debilitating condition in which the cartilage that provides cushioning within bone joints gradually degrades. Health care costs of treating arthritis in California alone has been estimated at over $12 billion and that figure is already … Continue reading Clever technique uncovers role of stem cells in cartilage repair
An unexpected link: immune cells send muscle injury signal to activate stem cell regeneration
We’ve written many blogs over the years about research focused on muscle stem cell function . Those stories describe how satellite cells, another name for muscle stem cells, lay dormant but jump into action to grow new muscle cells in response to injury and damage. And when satellite function breaks down with aging as well as … Continue reading An unexpected link: immune cells send muscle injury signal to activate stem cell regeneration
Confusing cancer to kill it
Confusion is not a state of mind that we usually seek out. Being bewildered is bad enough when it happens naturally, so why would anyone actively pursue it? But now some researchers are doing just that, using confusion to not just block a deadly blood cancer, but to kill it. Today the CIRM Board approved … Continue reading Confusing cancer to kill it
Reprogramming cells with a nanochip, electricity and DNA to help the body to heal itself
The axolotl, a member of the salamander family, has amazing regenerative abilities. You can cut off its limbs or crush its spinal cord and it will repair itself with no scarring. A human’s healing powers, of course, are much more limited. To get around this unfortunate fact, the field of regenerative medicine aims to develop … Continue reading Reprogramming cells with a nanochip, electricity and DNA to help the body to heal itself
One man’s journey with leukemia has turned into a quest to make bone marrow stem cell transplants safer
I read a story yesterday in Science Magazine that really stuck with me. It’s about a man who was diagnosed with leukemia and received a life-saving stem cell transplant that is now threatening his health. The man is name Lukas Wartman and is a doctor at Washington University School of Medicine in St. Louis. He … Continue reading One man’s journey with leukemia has turned into a quest to make bone marrow stem cell transplants safer
One day, scientists could grow the human cardiovascular system from stem cells
The human cardiovascular system is an intricate, complex network of blood vessels that include arteries, capillaries and veins. These structures distribute blood from the heart to all parts of the body, from our head to our toes, and back again. This week, two groups of scientists published studies showing that they can create key components … Continue reading One day, scientists could grow the human cardiovascular system from stem cells
Stories that caught our eye: smelling weight gain, colon cancer & diet and diabetes & broken bones
How smelling your food could cause weight gain (Karen Ring). Here’s the headline that caught my eye this week: “Smelling your food first can make you fat…” It’s a bizarre statement, but the claim is backed by scientific research coming from a new study in Cell Metabolism by researchers at the University of California Berkeley. … Continue reading Stories that caught our eye: smelling weight gain, colon cancer & diet and diabetes & broken bones
Stem Cell Stories that Caught our Eye: finding the perfect match, imaging stem cells and understanding gene activity
Here are the stem cell stories that caught our eye this week. Enjoy! LAPD officer in search of the perfect match. This week, the San Diego Union-Tribune featured a story that tugs at your heart strings about an LAPD officer in desperate need of a bone marrow transplant. Matthew Medina is a 40-year-old man who was … Continue reading Stem Cell Stories that Caught our Eye: finding the perfect match, imaging stem cells and understanding gene activity
Latest space launch sends mice to test bone-building drug
Astronauts on the International Space Station (ISS) received some furry guests this weekend with the launch of SpaceX’s Dragon supply capsule. On Saturday June 3rd, 40 mice were sent to the ISS along with other research experiments and medical equipment. Scientists will be treating the mice with a bone-building drug in search of a new … Continue reading Latest space launch sends mice to test bone-building drug
