London, Mar 16 (ANI): Scientists have discovered a gene which they claim could help make regrowing amputated limbs, broken backs and even damaged brains a reality.
The gene p21, researchers claim, appears to block the healing power enjoyed by some creatures including amphibians but lost through evolution to all other animals.
By turning off p21, the process [...]

Washington, Sept 15 (ANI): In a novel study, scientists from University of North Carolina and the College of Arts and Sciences have identified a novel mechanism that triggers blood vessel growth.

They have found that vascular networks form and expand by “sprouting” similar to the way trees grow new branches.

The process allows fresh [...]

Washington, Sep 8 (ANI): Fat that is left after liposuction is a huge bank of versatile cells that could be more quickly and easily coaxed to become induced pluripotent stem (iPS) cells than the often used skin cells, according to a study by researchers at Stanford’s School of Medicine.

Lead researcher Dr. Michael Longaker has even [...]

London, Aug 29 (ANI): Inching closer to curing diseases like Parkinson’s using cells generated from a patient’s own body, researchers have successfully reprogrammed human nerve cells back to an embryo-like state by using just a single gene.

It is known that embryonic stem cells are pluripotent – they can develop into any of the body’s cell [...]

Washington, August 25 (ANI): University of Wisconsin-Madison researchers have successfully grown multiple types of retina cells from two types of stem cells, giving new hope that damaged retinas may soon come to be repaired by cells grown from the patient’s own skin.

The researchers have also said that their discovery may soon lead to laboratory models [...]

Melbourne, Aug 24 (ANI): A team of Australian scientists has genetically modified human embryonic stem cells to glow red when they develop into premature red blood cells.

The breakthrough is seen as the next step in producing artificial blood.

Dr Andrew Elefanty at Monash University in Melbourne and his colleagues inserted specific genes that code for colour, [...]

London, July 9 (ANI): Scientists at the University of California, San Francisco claim to have identified a gene crucial to maintaining embryonic stem cells’ all-purpose, pluripotent state.

The researchers say that their finding may prove helpful in improving the scientific understanding of how cells acquire their specialized states, and provide a strategy to efficiently reprogram mature [...]

London, July 9 (ANI): Scientists are calling for more tests to ensure that artificial sperm created by some British researchers are identical to their natural counterpart, saying that further proof may make them a valuable tool to understand male infertility.

Karim Nayernia and his colleagues at the University of Newcastle recently treated male embryonic stem [...]

Washington, July 4 (ANI): Researchers at the University of California-Los Angeles (UCLA) have shown that there are certain molecular differences between embryonic stem cells and skin cells skin cells reprogrammed into embryonic-like cells.

Their work has made them the first ever research team to show that the two cell types are clearly distinguishable from each [...]

London, July 2 (ANI): While salamanders are known for their ability to regenerate lost limbs, damaged lungs, sliced spinal cord, and even bits of lopped-off brain, scientists have now shown that humans too possess a [...]

London, May 30 (ANI): Scientists at Massachusetts General Hospital in Boston and the Harvard Stem Cell Institute claim that they have isolated such embryonic stem cells from mice as are capable of differentiating into mature cardiac muscles.

This work attains significance because the cells identified by the researchers can be a powerful tool in animal [...]

Washington, May 15 (ANI): Stem cells, when transplanted into mouse embryos, have been found to halt or reverse cardiac injury after heart attack in adulthood, according to a new study.

The researchers involved in the study delivered embryonic stem cells to mouse embryos in the earliest stages of development, and found that the resulting mice [...]

Washington, May 7 (ANI): Paving the way for advancement in the field of stem cell therapy, scientists have discovered a method to potentially eliminate the tumour-risk factor in utilizing human embryonic stem cells.

Human embryonic stem cells are theoretically capable of differentiation to all cells of the mature human body, and are hence defined as “pluripotent”.

The [...]

Washington, Apr 21 (ANI): Embryonic stem cells have long been coveted for their potential to treat a multitude of diseases. Now, researchers have successfully reprogrammed cells found in circulating blood into cells that are molecularly and functionally indistinguishable from embryonic stem cells.

The new study may provide a readily accessible source of stem cells and an [...]

London, Apr 19 (ANI): The world’s first stem cell therapy to cure the most common cause of blindness has been developed by British researchers.

The research team believes that the procedure, which can tackle age-related macular degeneration (AMD), will become a routine, one-hour method that will be generally available in six or seven years’ time.

The treatment [...]

Washington, April 14 (ANI): Scientists at the Burnham Institute for Medical Research (Burnham) have come up with a way to convert human embryonic stem cells (hESCs) into neural progenitor cells, which may be ideal for transplantation.

Lead researcher Dr. Alexei Terskikh says that the new method to create these committed neural [...]

London, Apr 13 (ANI): A stem cell therapy to restore lost vision in older adults might be available by 2012, say researchers.

Scientists at University College London aim to kick off patient trials of the treatment for age-related macular degeneration (AMD) by 2012.

If the tests prove successful, a treatment could be available four years later.

The [...]

Washington, Mar 29 (ANI): In a breakthrough study, researchers have developed a new stem cell therapy that may help in treating hearing impairment.

Deafness typically involves the loss of sensory receptors, called hair cells, for their “tufts” of hair-like protrusions, and their associated neurons.

Led by Dr. Marcelo N. Rivolta of the University of Sheffield, researchers have [...]

Washington, Mar 25 (ANI): A team of scientists at Oregon State University has identified a gene in the human body that seems to be the master regulator for skin development.

According to researchers, their discovery could help address everything from skin diseases such as eczema or psoriasis [...]
