It’s a doctor’s dream — an unlimited supply of disease-free blood.
And it may not be the stuff of fiction for long, reports CBS News correspondent Elizabeth Palmer.
Someone in the United States needs blood every two seconds. In surgery, on cancer words, on the nation’s battlefields — blood transfusions save lives.
But in the U.S., demand often exceeds supply. And elsewhere, especially in the developing world, there’s a real chance the blood cud be contaminated with diseases such as AIDS or Hepatitis C.

Enter Dr. Marc Turner, a cell biologist from Scotland who received a multi-million dollar research grant to try to make blood in his lab from human stem cells.
“These cells are being generated from human embryonic stem cells, which themselves are generated from three-to-five-day-old human embryos,” Turner says.
Palmer explains that stem cells can be coaxed, theoretically, to grow into any human body part.

A University of Bristol team extracted stem cells from the veins, then used them to stimulate new blood vessel growth in mice, Circulation reports.

The researchers say their findings could bring treatments to repair damaged heart muscle one step closer.

However, a stem cell expert warned that they remained some years away.

Stem cells are attractive to medical researchers because they have the ability to produce many different types of human cell, opening up the possibility of repair or renewal for tissues ravaged by disease or injury (…)

The adult stem cell nutrition is the world’s first natural stem cell enhancer, supports the natural release of adult stem cells which, Rebuild, Renew, Rejuvenate the Body!

Numerous studies performed by various scientific teams throughout the world, including the National Institute of Health have clearly established that the higher the levels of circulating stem cells the better the ability of the body to maintain optimal health.

A recent publication in the New England Journal of Medicine reported that the level of stem cells in the blood was one of the best indicators of cardiovascular health. Elevating the number of stem cells in the blood has been shown to improve health in many ways. This stem cell nutrition supports the natural release of stem cells by 25-30%, which is bound to assist the body in maintaining optimal health.

In a ray of hope for millions of leukaemia patients, American scientists have claimed to have developed a technique which multiplies the small number of stem cells in the donor blood, making it much more potent for the treatment of the fatal disease.

It also eliminates the need for a matching donor, whose bone marrow is usually transplanted to the patient, according to a study which appeared in the journal Nature Medicine. Traditionally, there was always a risk that the patient’s body may reject the new cells from a donor.

Don’t worry about your child’s loss of teeth or if they have immature ones as doctors at AIIMS can regrow them using stem cell technique by just making a minute slit in their root.
“We at AIIMS are treating children with infected, immature teeth as a result of traumatic injuries, by using locally available indigenous stem cells,” Dr Naseem Shah, Chief of the Centre for Dental Education and Research, AIIMS said.

She explained that the root forms the most important part of the tooth. It anchors the tooth within the bone and houses the pulp (tiny blood vessels and nerves) which extends to the underlying bone and helps to nourish and give feeling to the tooth.
Any trauma to the teeth may lead to infection and death of the pulp, infection in the bone and arrest of the root development. Such roots are very fragile and may fracture, ultimately leading to loss of tooth.

Plerixafor has allowed doctors to collect stem cells from patients where there had been previous difficulties.
The drug, which has only recently been licensed, is being used at the Beatson West of Scotland Cancer Centre.

Stem cells therapies are used to treat people with cancer of the blood. The cells are collected and reintroduced to a patient after chemotherapy.
Doctors often encounter problems collecting enough stem cells from about one in 10 cancer patients to undergo treatment.

Plerixafor has, so far, had a 100% success rate in allowing doctors at the cancer centre to collect enough cells from patients who fall into this category.
Blood specialist, Dr Kenneth Douglas, explained how the drug worked.

“Basically it blocks a chemical scent that stem cells sniff for that tells them they’re in the bone marrow,” he said.
“If you block that chemical scent they get confused and agitated and they think they are not in the bone marrow any more and they start wandering into the blood stream looking for the bone marrow.”

When more stem cells “start wandering into the blood” doctors are able to collect them for future treatment.
One patient who has benefited from this approach is retired professional golfer, Billy McCondachie.

He said his age was a barrier to potential stem cell treatment.
“We were only able to get about half of my stem cells out until Dr Douglas came along with this new drug,” he said.

“One could say that pretty much saved my life.”
The centre in Glasgow has now treated 13 people with the drug and every one has been able to proceed with stem cell treatment.
