A Null Result for Vigorous Exercise and Telomere Length

12 minutes agoHealth / Aging : Fight Aging

Telomeres are the caps at the ends of chromosomes, shortening with each cell division in normal cells. When very short a cell self-destructs or falls into a senescent state and ceases further replication. Stem cells maintain long telomeres...Show More Summary

Disease-a-Week Challenge #1: How the California Stem Cell Program is Battling Lou Gehrig's Disease

Last year, chronic disease cost America as much as all federal income tax and the national debt combined. Let me prove that. First, the money we spend on chronic (long-lasting or incurable)disease is three-quarters of every health care dollar. Total medical care in 2014 was approximately $3.1trillion. Show More Summary

Cellular Senescence and Stem Cell Aging

yesterdayHealth / Aging : Fight Aging

In recent years, researchers have provided evidence to suggest that cellular senescence mechanisms are partly involved in the decline of stem cell activity in aging. It is an open question as to how this interacts with other signaling mechanisms also recently shown to influence the suppression of stem cell tissue maintenance. Show More Summary

Suge Knight Refuses to Leave Cell For Robbery Hearing

Suge Knight was scheduled to appear in court Wednesday for a hearing stemming from last October’s robbery case where he allegedly snatched a woman’s camera. But Knight refused to leave his cell, according to the Associated Press.

New study warns of untested Lyme disease ‘cures’

From 'urine therapy' to magnets to stem cell transplants, study casts doubt on the efficacy of purported Lyme treatments The post New study warns of untested Lyme disease ‘cures’ appeared first on

Another Example of Induced Pluripotency Reversing Mitochondrial Damage in Aging

2 days agoHealth / Aging : Fight Aging

In the past researchers have shown that reprogramming adult cells to create induced pluripotent stem cells sweeps away some specific forms of damage observed in old cells. In particular it seems to clean up damaged mitochondria, which is of considerable interest given the role of mitochondrial DNA damage in aging. Show More Summary

Clinical trial reduces stress of cancer caregivers

A randomized control trial demonstrates an intervention that successfully reduces the stress of caregivers in the context of cancer patients treated with stem cell transplantation. The study enrolled 148 caregivers of allogeneic hematopoietic stem cell (Allo-HSCT) patients.

Infusions of donor bone marrow cells help children with inherited skin blistering

Promising results from a trial of a new stem-cell based therapy for a rare and debilitating skin condition suggest that the therapy, involving infusions of stem cells, provide pain relief and to reduce the severity of this skin condition for which no cure currently exists.

Can plant stem cells grow more hair? Episode 84

Perry kicks of the episode by telling he wants to go beauty spelunking in the Salt Caves of Norridge. The place is actually called Galos Caves and it was built in Chicago because the Midwest has a low iodine content in the air. According to the company, the technology of building salt-iodine caves is based on the […]

Complex signaling between blood, stem cells controls regeneration in fly gut

Having a healthy gut may well depend on maintaining a complex signaling dance between immune cells and the stem cells that line the intestine. Scientists report significant new insight into how these interactions control intestinal regeneration after an infection. Show More Summary

Team pinpoints genes that make plant stem cells, revealing origin of beefsteak tomatoes

A team of scientists has identified a set of genes that control stem cell production in the tomato. Mutations in these genes explain the origin of mammoth beefsteak tomatoes. More importantly, the research suggests how breeders can optimize fruit size in potentially any fruit-bearing crop.

Neural Stem Cell Transplant Treats Parkinson's in Rats

4 days agoHealth / Aging : Fight Aging

The proximate cause of the most visible symptoms of Parkinson's disease is the progressive loss of a small but vital population of dopamine-generating neurons. This loss happens to everyone, but for a variety of underlying reasons, not all of which are clear at this time, people with Parkinson's experience a more rapid loss of these cells.

Send 'Crashlands' Developer Sam Coster Some Good Vibes for his Cancer Recovery

As you recently read here on TA, Sam Coster of Butterscotch Shenanigans is fighting a remission of his lymphoma. He's currently in the hospital as he's recovering from a final round of chemo and a stem cell transplant that will beat this cancer once more. Now, the Coster brothers want you to send Sam some

Unlocking the Potential of Regenerative Medicine

The Center for iPS Cell Research and Application (CiRA) at Kyoto University was established in April 2010 to advance iPS (induced pluripotent stem) cell technology for clinical application. Currently, we have about 30 research teams conducting basic research on iPS cells as well as investigating their use for new medical treatments. Show More Summary

Human stem cell model reveals molecular cues critical to neurovascular unit formation

Using human embryonic stem cells, researchers have created a model that allows them to track cellular behavior during the earliest stages of human development in real-time. The model reveals, for the first time, how autonomic neurons and blood vessels come together to form the neurovascular unit.

Trials of Cell Therapies for Heart Regeneration

last weekHealth / Aging : Fight Aging

Stem cell therapies to repair heart damage were one of the first to become widely available via medical tourism, and have been underway in earnest for more than a decade now. There is evidence from their use that benefits can be attained for patients. Show More Summary

Human Stem Cell Model Reveals Molecular Cues Critical to Neurovascular Unit Formation

Using human embryonic stem cells, researchers at University of California, San Diego School of Medicine and Moores Cancer Center and Sanford-Burnham Medical Research Institute created a model that allows them to track cellular behavior during the earliest stages of human development in real-time.

Stem cells still uncharted territory in sports

C.J. Nitkowski had nothing to lose in spring 2011. The rotator cuff in his left shoulder that he'd relied on during his decade as a major league pitcher was in tatters. He was 38 and his fastball traveled a Little League-worthy 50 m...

Blood turned into neural cells

Scientists at McMaster University have discovered how to make adult sensory neurons from human patients simply by having them roll up their sleeve and providing a blood sample. Specifically, stem cell scientists at McMaster can now directly...Show More Summary
