Stem cells used to repair eye surface

TONY EASTLEY: In a world first Melbourne researchers have rebuilt the surface of a human eye, using adult stem cells grown on a special type of contact lens.

One of the researchers is Karl Brown from the Centre for Eye Research Australia. He’s speaking with Ashley Hall.

KARL BROWN: We collected the adult stem cells from the very edge of the cornea. In the final version this could be the patient’s own eye if they have a good eye and an injured eye. Or it could be from material left over that is not used for a corneal transplant.

Repair cartilage using stem cells

The study Sun has been working on in Dr. Farshid Guilak’s laboratory has found that engineered cartilage constructed from a particular type of stem cell integrate well with host cartilage, but not necessarily in a uniform way.

Sun was one of about thirty biomedical engineering students who presented at the department’s graduation with distinction reception on April 26. Other students have been working on exciting projects in optic imaging of tumors, synthetic biology, and deep brain stimulation, among other topics.

Sun’s project focused on how induced pluripotent stem cells can be used to study cartilage regeneration and repair.

Stem cells raise hopes of cure for baldness

Japanese researchers have successfully grown hair on hairless mice by implanting follicles created from adult stem cells, they announced Wednesday, sparking new hopes of a cure for baldness.

Led by professor Takashi Tsuji from Tokyo University of Science, the team bioengineered hair follicles and transplanted them into the skin of hairless mice.

The creatures eventually grew hair, which continued regenerating in normal growth cycles after old hairs fell out.

When stem cells are grown into tissues or organs, they usually need to be extracted from embryos, but Tsuji and his researchers found hair follicles can be grown with adult stem cells, the

New Source of Stem Cell Generation Pioneered at UCF

A process that prompts a single gene to generate millions of supercharged stem cells, which can then turn into any kind of cell a body needs to repair itself, has been patented at the University of Central Florida.

Stem cells have long been regarded as a holy grail of sorts in the medical world, because they hold so much potential for treating and perhaps curing some of the most challenging diseases in our time, such as Alzheimer’s, Parkinson’s and diabetes.

But a limited supply of stem cells and ethical issues associated with cells from embryonic donors have stalled

Kidneys created from stem cell

It raises hopes that kidney disease patients will one day be able to grow their own new organs with no risk of rejection.

Kidneys 5mm long – the size of those in foetuses – were made using a combination of cells from amniotic fluid, which surrounds babies in the womb, and animal foetal cells.

It is hoped the organs could be grown to maturity if implanted in a patient. In future, people’s amniotic fluid could be retained at birth, allowing it to be used later if they develop kidney disease.

‘The idea is to start with human
