A cancer’s surprise origins caught in action

A cancer's surprise origins caught in action
Researchers have, for the first time, visualized the origins of cancer from the first affected cell and watched its spread in a live animal. Their work could change the way scientists understand melanoma and other cancers and could lead to new, early treatments before the cancer has taken hold.

Ultrasound-based therapy for cardiac stem cells recovery

Ultrasound-based therapy for cardiac stem cells recovery
When cardiac stem cells undergo low-intensity pulsed ultrasound treatment, these cells can perform continuing modifications, tissue remodeling and regeneration of damaged cardiac tissue after a heart attack, report researchers.

Seaweed offers solution to transporting stem cells, wound treatment

Seaweed offers solution to transporting stem cells, wound treatment
Stem cells have been put into plasters and bandages to help heal wounds for the first time, thanks to a newly developed technique. The method of encasing stem cells in an alginate gel made from seaweed makes them practical to use, adaptable and easy to store — even at room temperature.

Protein combination improves bone regeneration, study shows

Protein combination improves bone regeneration, study shows
A combination of proteins that could improve clinical bone restoration, and could lead towards the development of therapeutic treatments for skeletal defects, bone loss and osteoporosis, report researchers. They found that the combination of two proteins, NELL-1 and BMP2, increased bone formation while inhibiting the formation of fat cells. By contrast, NELL-1 encourages stem cells to form bone cells...

Breakthrough in human cell transformation could revolutionize regenerative medicine

Breakthrough in human cell transformation could revolutionize regenerative medicine
A breakthrough in the transformation of human cells by an international team of researchers could open the door to a new range of treatments for a variety of medical conditions.

Scientists identify molecule that appears to fuel deadly genetic illness

Scientists identify molecule that appears to fuel deadly genetic illness
Researchers have identified a molecular target and experimental treatment strategy for DNA repair defects behind Fanconi anemia — a complex genetic disorder responsible for birth anomalies, organ damage, anemia and cancer. The findings also create a bit of molecular intrigue. It involves how cells used in the study — which still had the Fanconi anemia (FA) DNA repair defect — were...

Signals that make early stem cells identified

Signals that make early stem cells identified
Now, researchers at The Rockefeller University have identified a new mechanism by which cells are instructed during development to become stem cells. The results, published in Cell on January 14, help explain how communication between cells mediates this process, and may have implications for skin cancer treatments. Clusters of stem cells receive signals from other nearby cells that instruct them...

Source of stem cells used for bone marrow failure treatment varies worldwide

Source of stem cells used for bone marrow failure treatment varies worldwide
The use of peripheral blood stem cells and bone marrow as stem cell sources for hematopoietic stem cell transplantation in patients with bone marrow failure has been the focus of recent research. Authors studied the factors associated with the use of each stem cell source.

Scientists root out ‘bad seeds’ of liver cancer

Scientists root out 'bad seeds' of liver cancer
Researchers have found the ‘bad seeds’ of liver cancer and believe they could one day reprogram them to remain responsive to cancer treatment, a new study has found. The key to disrupting chemo-resistant stem cells that become liver tumors from multiplying is to target the stem cell marker.
