Greying hair, crow’s feet, an injury that’s taking longer to heal now one is older, faced with the unmistakable signs of aging, most people have had a least one fantasy … Continue Reading Epigenetic reprogramming used to reverse signs of aging in animal model.
The limited removal of metabolic waste products in dialyzed kidney patients leads to high morbidity and mortality. A bioartificial kidney could replace the need for dialysis or transplantation in the … Continue Reading Researchers develop functional living membrane in massive leap towards a bioartificial kidney.
Lung disease causes more than 200,000 deaths annually in the United States. Although the lung is generally considered slow to respond to disease and injury, it does undergo regenerative processes, … Continue Reading Researchers develop tissue-engineered model of human lung and trachea.
It is known that around the body, fat deposits contain many mature fat cells and small numbers of stem cells. These stem cells can differentiate into more fat cells, however, … Continue Reading Hormone that controls maturation of fat stem cells identified.
It is known that neurons in the central nervous system of higher vertebrates are formed during embryonic development and that neurogenesis does not occur postnatally, except in the hippocampus. Buried … Continue Reading Researchers sucessfully make memories stronger and more precise during aging in mice.
Demyelinating diseases, such as multiple sclerosis and leukodystrophy, are characterized by damage to the protective myelin sheath that surrounds the axons of neurons. This demyelination can be caused by an … Continue Reading Cell therapy successfully promotes axon remyelination in an animal model.
Epigenetic dysfunction is implicated in many neurological and psychiatric diseases, including Alzheimer’s disease and schizophrenia. Consequently, histone deacetylases (HDACs) are being aggressively pursued as therapeutic targets. However, a fundamental knowledge … Continue Reading Researchers image the epigenetics of the human brain for the first time ever.
Like a magician, the freshwater flatworm known as planaria can survive decapitation or even being cut into many pieces. Its ability to fully regenerate from tiny remnants of tissue is … Continue Reading Elusive key molecular signal for planarian stem cell regeneration identified.
