A human growth factor that stimulates blood stem cells to proliferate in the bone marrow reverses memory impairment in mice genetically altered to develop Alzheimer's disease. picked by AutumnLotus 5 months ago

Fully functioning teeth have been grown from stem cells planted in the mouths of mice, scientists said today.

The researchers in Japan hope the breakthrough could proved not only to be an important step towards being able to replace teeth in humans but eventually replacing organs, lost or damaged as a result of disease, injury or aging. picked by AutumnLotus 4 months ago

During an experimental brain surgery to reduce a patient's appetite, surgeons triggered a déjà vu event. The patient had vivid and precise memories of something that happened 30 years ago. The possibilities of this being used to help Alzheimer's patients are being investigated. picked by 2manyusernames 2 years ago

The success in repairing a damaged layer of retinal cells in mice implies that blood stem cells taken from bone marrow can be programmed to restore a variety of cells and tissues, including ones involved in cardiovascular disorders such as atherosclerosis and coronary artery disease. picked by kakana 4 months ago

A robot controlled by a blob of rat brain cells could provide insights into diseases such as Alzheimer's, University of Reading scientists say.

Ordinary cells reprogrammed to act like embryonic stem cells can help repair damaged heart tissue in mice, researchers reported on Monday in a study that shows a potential practical use for the experimental cells. picked by Bingo 4 months ago

Using stem cells, scientists were able to grow completely new prostate glands in mice. The prostate is a gland that aids in creating and expelling semen, and is often the cause of cancer in older men. But now that researchers can grow prostates in mice, will doctors be regrowing human prostates any time soon? picked by suebe 1 year ago

Globs of human fat removed during liposuction conceal versatile cells that are more quickly and easily coaxed to become induced pluripotent stem cells, or iPS cells, than are the skin cells most often used by researchers, according to a new study from Stanford's School of Medicine. picked by Bingo 3 months ago

A team at the University of Sheffield said on Thursday they had discovered how to turn stem cells into ones that behave like sensory hair cells or auditory neurons, which could then be surgically inserted into the ear to restore lost hearing. picked by AutumnLotus 8 months ago

A team of scientists from the University of Wisconsin-Madison School of Medicine and Public Health has successfully grown multiple types of retina cells from two types of stem cells — suggesting a future in which damaged retinas could be repaired by cells grown from the patient's own skin. picked by AutumnLotus 3 months ago

An artificial brain cell that could be used to treat diseases such as Parkinson's has been created by scientists.

The 'delivery electrode' works in the same way as nerve cells in the brain by releasing neurotransmitters. picked by AutumnLotus 5 months ago

Japanese researchers said Thursday they had created functioning human brain tissues from stem cells, a world first that has raised new hopes for the treatment of disease. picked by karenben 1 year ago

Chinese scientists have given cells from adult pigs the ability to turn into any tissue in the body, just like embryonic stem cells.
They hope the breakthrough could aid research into human disease, and the breeding of animals for organ transplants for humans.
It may also enable the development of pigs that are resistant to diseases such as swine flu. picked by bingo 6 months ago

A research group has achieved an additional step for the potential replacement of damaged brain cells after injury or disease: functional nerve cells can be generated from astroglia, a type of supportive cells in the brain by means of special regulator proteins. picked by AutumnLotus 2 years ago

When it comes to the hippocampus, a brain structure vital to certain types of memory, size matters. Numerous studies have shown that bigger is usually better. Now researchers have found that elderly adults who are more physically fit tend to have bigger hippocampi and better spatial memory than those who are less fit. picked by AutumnLotus 9 months ago

Harvard Stem Cell Institute researchers at Massachusetts General Hospital have identified the earliest master human heart stem cell from human embryonic stem cells - ISL1+ progenitors - that give rise to a family of cells that form the essential portions of the human heart. picked by AutumnLotus 5 months ago

Scientists know little about how the brain assigns cells to participate in encoding and storing memories. Now a UCLA/University of Toronto team has discovered that a protein called CREB controls the odds of a neuron playing a role in memory formation. picked by AutumnLotus 3 years ago
