Single cell sequencing opens new avenues for eradicating leukemia at its source
Cancer stem cells that elude conventional treatments like chemotherapy drive long-term cancer growth and relapse. These cells are difficult to isolate and study because of their low abundance and similarity to other stem cells. Researchers have created a new method that can distinguish cancer stem cells, mature cancer cells and otherwise healthy stem cells based on their genetics and gene expression. The findings open new avenues for cancer research personalised medicine.
Mechanism by which exercise strengthens bones and immunity
Scientists have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study also shows that movement-induced stimulation is required for the maintenance of this niche, as well as the bone and immune-forming cells that it contains. Together, these findings identify a new way that exercise strengthens bones and immune function.
Scientists repair injured spinal cord using patients' own stem cells
Intravenous injection of bone marrow derived stem cells (MSCs) in patients with spinal cord injuries led to significant improvement in motor functions, researchers report.
How a longevity gene protects brain stem cells from stress
A gene linked to unusually long lifespans in humans protects brain stem cells from the harmful effects of stress, according to a new study.
Researchers identify mechanisms that are essential for proper skin development
Latest discovery could improve development of future stem cell therapies and cancer treatments.
