More good news from some researchers at UCLA:
UCLA stem cell scientists have reprogrammed human skin cells into cells with the same unlimited properties as embryonic stem cells without using embryos or eggs.
Led by scientists Kathrin Plath and William Lowry, UCLA researchers used genetic alteration to turn back the clock on human skin cells and create cells that are nearly identical to human embryonic stem cells, which have the ability to become every cell type found in the human body.
The implications for disease treatment could be significant. Reprogramming adult stem cells into embryonic stem cells could generate a potentially limitless source of immune-compatible cells for tissue engineering and transplantation medicine.
At least this would give the scientists who are trying to get those embryonic stem cells to actually work a way to get them without destroying embroyos. Interesting that the release does say:
These new techniques to develop stem cells could potentially replace a controversial method used to reprogram cells, somatic cell nuclear transfer (SCNT), sometimes referred to as therapeutic cloning. To date, therapeutic cloning has not been successful in humans. However, top stem cell scientists worldwide stress that further research comparing these reprogrammed cells with stem cells derived from embryos, considered the gold standard, is necessary.
At least they have a way to research without destroying living things. Not that they actually want to stop destroying embryos:
“It is important to remember that our research does not eliminate the need for embryo-based human embryonic stem cell research, but rather provides another avenue of worthwhile investigation.”
No – you create stem cells which you report as being genetically identical to the originals and still you propose destroying life.
Giving hope for possible treatments for humans with spinal injuries. And this is yet another example of possible treatment from ADULT stem cells. Still nothing at all from embryonic stem cells.
|A Toronto-led team of researchers has found a way to use stem cells derived from skin to treat spinal cord injuries in rats.
|The finding lends promise to the idea that stem cells could one day be used to heal spinal cord injuries in humans, helping thousands of Canadians to walk again.
|Over the course of their research, the team found that skin-derived stem cells share characteristics with embryonic neural stem cells, which generate the nervous system.
|Before treatment, the injured rats had a cavity in their spinal cord, a result of their injury. But after treatment, Miller said the Schwann cells had created a bridge that spanned the cavity, and helped nerves grow through the bridge.
The next step is to see whether stem cells derived from human skin can produce similar results.
“We are highly encouraged,” said Miller.
Yet another advance for ADULT stem cells. We are still waiting on any viable treatment from embryonic stem cells.
| Cardiac patients will soon be able to ‘grow their own’ heart valves and have them transplanted within weeks of seeing a doctor.The groundbreaking treatment, developed by British surgeons, will create heart tissue from stem cells from the patient’s body.
The technique offers hope to millions who suffer heart disease.
Scientists said the valves would not be rejected after a transplant because the tissue will have come from the patient and be genetically identical.
|He added: “The ultimate goal is to produce an ‘off the shelf’ product which will not cause an immune response from patients. This should be possible in the next five to eight years.”
A man’s vision has been restored by a corneal patch grown from adult stem cells by a team at the University of Melbourne’s Centre for Eye Research Australia (CERA) and the Bernard O’Brien Institute of Microsurgery (BOBIM).
The patch, which replicates the cornea, was cultivated from a single stem cell from a donor eye and was transplanted to the surface of the man’s eyes.
The research team was led by Dr Mark Daniell (CERA) and Dr Erik Thompson (BOBIM).
The process, known as a limbal stem cell transplant, is thought to be the first of its kind in Australia. The Melbourne success significantly advances international research in limbal stem cell transplantation in the eyes.
The patient had severe vision loss caused by stem cell failure on the surface of the eye, causing scarring and a vascularised and opaque appearance.
He says the surface of the man’s eyes was removed and the patch (about 50mm long and a micron thick) was applied and is healing well. “This technique can now assist people with alkaline burns who have damage to the surface of their eyes.”
Dr Daniell and his team are now working toward developing a totally bio-engineered cornea, using a stem cell extracted from elsewhere on a person’s body other than the eye.
Yet another advance for adult stem cells. Number of embryonic stem cell treatments available? Still zero.
The good news that the progress seen in working with adult stem cells continues with this from Britain:
A British research team led by the world’s leading heart surgeon has grown part of a human heart from stem cells for the first time. If animal trials scheduled for later this year prove successful, replacement tissue could be used in transplants for the hundreds of thousands of people suffering from heart disease within three years.
Sir Magdi Yacoub, a professor of cardiac surgery at Imperial College London, has worked on ways to tackle the shortage of donated hearts for transplant for more than a decade. His team at the heart science centre at Harefield hospital have grown tissue that works in the same way as the valves in human hearts, a significant step towards the goal of growing whole replacement hearts from stem cells.
Of course, the word adult is never used in the headline or any of this news report (what else would you expect from a good liberal paper like the Guardian?). So what leads me to say its adult stem cells? Things like:
By using chemical and physical nudges, the scientists first coaxed stem cells extracted from bone marrow (emphasis mine – but to show that the cells were extracted from living humans, not embryos) to grow into heart valve cells.
Growing a suitably-sized piece of tissue from a patient’s own stem cells would take around a month but he said that most people would not need such individualised treatment. A store of ready-grown tissue made from a wide variety of stem cells could provide good matches for the majority of the population.
The other clue that its adult stem cells? If they had used embryonic ones it would be plastered all over the world at 1000 decibel level.
Wonderful news for people suffering from diabetes – possible cure able to come from their own bone marrow:
Scientists have used stem cells from human bone marrow to repair defective insulin-producing pancreatic cells responsible for diabetes in mice.
The treatment also halted damage to the kidneys caused by the condition.
Researchers from New Orleans’ Tulane University are hopeful it can be adapted to treat diabetes in humans.
But you will strain your eyes reading this article to find the word “adult”. Its part of the ongoing effort to confuse and obscure on the part of the Culture of Death.
