Damage to axons in the central nervous system (CNS) typically results in permanent damage and severed axons in the adult mammalian CNS do not spontaneously regenerate to restore lost functions. … Continue Reading Researchers regenerate damaged nerves via the eye using optogenetics.
Astrocytes are star-shaped cells in the brain that surround brain cells, known as neurons, protecting them from injury and enabling them to function properly. The brain contains billions of cells, … Continue Reading Study breaks new ground on the role and formation of astrocytes in the brain.
The molecular switches regulating human cell growth do a great job of replacing cells that die during the course of a lifetime. However, when they misfire, life-threatening cancers can occur. … Continue Reading Study identifies electrical control of cancer cell proliferation.
Heart regeneration a step closer as researchers identify progenitor cell exclusively for heart muscle.
Future therapies for failing hearts are likely to include stem-like cells and associated growth factors that regenerate heart muscle. Now, researchers from the University of Pennsylvania have just taken an … Continue Reading Heart regeneration a step closer as researchers identify progenitor cell exclusively for heart muscle.
While the overall rate of colorectal cancer is declining, previous studies show that colorectal cancer specifically among young patients is increasing. Results also show that colorectal cancer in patients younger … Continue Reading Human study shows colorectal cancer genetically different in older and younger patients.
In proof-of-concept experiments, researchers at University of California demonstrate the ability to tune medically relevant cell behaviours by manipulating a key hub in cell communication networks. The manipulation of this … Continue Reading How to reset a diseased cell.
RNA is both the bridge between DNA and the production of proteins known to carry out the functions of life, guiding the amount and type of protein mades. As messenger … Continue Reading The first ever study to map splicing changes during T cell development has been published.
Every time a person makes a memory, somewhere in their brain a tiny filament reaches out from one neuron and forms an electrochemical connection to a neighbouring neuron. A team … Continue Reading Mapping the neuroanatomy of a memory.
During pregnancy, the mother supplies the fetus with nutrients and oxygen via the placenta. If placental development is impaired, this may lead to growth disorders of the embryo or to … Continue Reading Researchers discover a new signaling pathway in embryonic development.
Glioblastomas are a highly aggressive type of brain tumour, with few effective treatment options. Moffitt Cancer Center researchers are one step closer to understanding glioblastoma development following the identification of … Continue Reading Researchers map protein pathway involved in brain tumour stem cell growth.
Tumours require blood to emerge and spread. That is why scientists at The University of Texas MD Anderson Cancer Center believe that targeting blood vessel cells known as pericytes may … Continue Reading Breast cancer metastasis slowed by targeting cells that regulate blood flow.
Researchers have known that transplanted human umbilical cord cells (HUCBCs) can have a restorative effect on the brain and brain function following a stroke. However, just how the cells exert … Continue Reading Precision medicine used to counteract oxidative stress in stroke animal model.
Researchers from KU Leuven have identified a new strategy for treating an inherited form of dementia after attempting to turn stem cells derived from patients into the neurons most affected … Continue Reading Patient stem cells used to make dementia-in-a-dish for the first time.
A University of Colorado study published in the journal Stem Cells has identified a program that makes stem cells damaged by radiation differentiate into other cells that can no longer … Continue Reading Researchers reprogram stem cells after radiation, lower cancer risk.
Sensory hair cell loss is the major cause of hearing loss and balance disorders. The postnatal mammalian inner ear harbors progenitor cells which have the potential for hair cell regeneration … Continue Reading Researchers regenerate inner ear hair cells via the Notch pathway to restore hearing.
Researchers from the UCLA have shown that two genes not previously known to be involved with the immune system play a crucial role in how progenitor stem cells are activated … Continue Reading Researchers identify two new genes involved in the immune system.
