How cells and cell fragments move in opposite directions in response to electric field

Researchers at  University of California, Davis have shown for the first time how whole cells and fragments orient and move in response to electrical stimuli like an electric field. Surprisingly enough, their results show that whole and fragments move in opposite directions, despite being governed by the same electric field. The findings help better our understanding of how the human body

Sugar-coated scaffolding guides and differentiates stem cells

One of the miracles of modern day medicine science, stem cells, are regarded by scientists as the basic building blocks for devising treatments, cures or transplants for some of today’s yet incurable diseases like Alzheimer or diabetes. The biggest hurdle researchers face is differentiating stem cells so that they may grow into a specific type of cell. Researchers at Manchester

3D printing stem cells could be used one day to ‘manufacture’ organs

We’re only in the early days of 3-D printing, but even now the breakthroughs made using such technology are most impressive like the genuine possibility of printing spare parts in space for the ISS, creating objects of great details on the nanoscale or even artificial muscles made using a 3-D printer. What’s fabulous though is that 3-D printing is developing

Massive database of of 1,500 stem cell lines derived from diseased cells set to aid drug development

The StemBANCC project, developed as a joint effort between the European Union and Europe’s pharmaceutical industry, is set to culture 1,500 pluripotent stem cell lines derived from the cells of diseased individuals like Alzheimer’s patients is currently planned. Using this massive database, researchers will be able to achieve much smoother and faster drug screening process in order to counter these diseases. The 50

Scientists grow mice from dish-cultured sperm and egg

Kyoto University researchers have produced normal, healthy mouse pups after inseminating a foster mother with eggs and sperm derived from stem cells, exclusively grown in a petri dish. This remarkable accomplishment came after last year scientists produced mouse pups from stem cell grown sperm. Their research might lead to the development of novel techniques through which infertile couples may conceive.

Hearing restored in gerbils by stem cell treatment – might work for the human ear, too

In an exceptional feat of medical and technical ingenuity, scientists have been able to restore partial hearing to deaf gerbils by implanting modified human embryonic stem cells in their ears. The success rate is pleasing, and offers solid ground on which human trials with a similar treatment might commence. There are many causes which might lead to hearing loss. The

Scientists grow rudimentary human liver in a dish

In an extraordinary feat of science, Japanese scientists have used induced stem cells to grow into a liver-like tissue in a dish. The researchers have a long way ahead of them before they can grow livers safe for human transplants, which is the main goal, however even at its current stage, the tissue grown by the researchers can satisfy rudimentary metabolic functions

How bad breath can save lives

An interesting conversation can instantly make a turn for the worst when bad breath hops into the scene. We’ve all had our share of bad experiences whether we were more or less forced to tolerate the repulsive stench of bad breath or we had a case of bad breath ourselves. Scientists at Nippon Dental University, however, have found that the

Stem cells treatment dramatically improves vision of the blind

Detailed in a recently published study, a team of ophthalmologists have successfully managed to improve the vision of both of their trial patients, which were declared legally blind due to macular degeneration, by inserting human embryonic stem cells into one eye of each person. Significant improvements were recognized shortly after the procedure, and continued to progress positively in the months

First chimera monkeys presented by scientists

In Greek mythology, the chimera is a fire breathing beast composed of several animal parts (lion body, snake-head tail, a goat head hanging from its back and so on), which has spurred the imagination of man for thousands of years. Though it is fairly clear that such an abomination never existed, apart from the infinite recesses of human imagination, scientist at the Oregon

Lab grown stem cells may mutate in time

According to a new study by researchers at University of Melbourne, prolonged stem cell cultures are subjected to a relatively significant risk of mutation, similar to those seen in human cancers. Their results is of capital importance as it shows that lab grown cell treatment might become useless, if left to “stir” for too long. The scientists studied 138 stem cell lines

When a pregnant mother is very sick, mouse fetuses send up stem cells to help

Amidst of all the talks and protest against stem cell treatment and companies shutting down, nature has found its own way of treating diseases with stem cells. When a pregnant mouse mother, for example, has a heart attack, her fetus donates some of its own stem cells to help and cure. Researchers started working on this experiment with two lines

Scientists grow new teeth from stem cells

A recently published remarkable study describes how scientists from Japan have successfully manage to grow teeth inside a lab using mice stem cells. Takashi Tsuji from Tokyo University of Science and his team managed to achieve this after extracting stem cells from the molars of mice. They then transported these cells to the lab where they eventually used them to

How aging can be cured in the future – a scientist’s view

If we’re to guide ourselves after Aubrey de Grey‘s telling, according to his predictions the first person who will live to see their 150th birthday has already been born, and as science advances along the decades at the current pace it does, he claims people born soon after the latter mentioned birthday will live to be 1,000. “I’d say we

British scientists create kidneys from stem cells

In a breakthrough discovery that could revolutionize transplants, British researchers have managed to create human kidneys from stem cells, which could lead to transplant patients growing their own organs; the artificial organs were created using human amniotic fluid and animal foetal cells. The kidneys are now about half of centimeter long, which is about what you would expect to find

Algae gene therapy could cure blindness

Researchers have managed to restore light perception to mice through gene therapy, by inserting algae genes into the retina. The treatment has succeeded in restoring the ability to sense light and dark to blind mice, and clinical trials in humans could begin in as little as two years. “The idea is to develop a treatment for blindness,” says Alan Horsager,

The Smell of Sound – how nasal stem cells treatment can prevent hearing loss

A research published earlier today in Stem Cells relates how stem cells scientists in Australia have managed to show that patients suffering from hearing disorders emerged during childhood could benefit from a stem cells procedure collected from one’s nose. The research focused on early-onset sensorineural hearing loss, which is caused by a loss of sensory cells or neurons in the

First trial of embryonic stem cells in humans

In was is a historic day, US doctors have officially begun the first trial of using human embryonic stem cells, as a result of the green light they got from regulators. The controversial method has been on the table for quite a while, and now The Food and Drug Administration has given a license to Geron to use stem cells

Menstrual blood a good source of stem cells?

Researchers are always seeking more and more ways that are viable and safe for gathering stem cells. Now it seems they’ve finally identified a potentially unlimited, noncontroversial, easily collectable, and inexpensive source – menstrual blood. Stromal stem cells – cells that are present in connective tissues – have recently been identified in endometrial tissues of the uterus. What that means

Human skin cells ordered to be embryonic stem cells

As expected, genetics evolves everyday and finds more new and unexpected solutions to some of the most puzzling problems we have faced yet. Such a problem was the ethical side of using embrionic stem cells. But now, it seems it won’t be necessary to figure out whether it’s ethical or not, because we can bypass it. This is because UCLA
