Adult stem cells used to grow a new heart

Researchers at the University of Minnesota used adult stem cells to create a living human heart that they hope will revolutionize transplants.

The breakthrough, said lead researcher Dr. Doris Taylor, could ultimately mean that “donated” hearts are no longer used in transplant operations, circumventing the ethical problems involved in organ donation and obviating the need for drugs to combat immune system rejection.

Dr. Taylor, director of the university’s Center for Cardiovascular Repair, is one of the world’s leaders in heart organ repair and regeneration and has said it is her goal to create a living heart that can be transplanted into a patient, entirely out of stem cells.

She presented her team’s findings at the American College of Cardiology’s annual conference in New Orleans.

“The hearts are growing, and we hope they will show signs of beating within the next weeks,” she told the Daily Mail. “There are many hurdles to overcome to generate a fully functioning heart, but my prediction is that it may one day be possible to grow entire organs for transplant.”

The breakthrough is a follow-up on work Dr. Taylor completed in 2008 in which her team used stem cells to rebuild the hearts of rats. They removed all the muscle cells in a rat heart, leaving just a “scaffold” of other tissues such as blood vessels and valves. This scaffold was then repopulated with stem cells, which took their cues from the scaffold tissue to regenerate healthy, functioning heart muscle.

Another scientific breakthrough for ethical adult stem cells.

CBS News discovers that adult stem cells produce more treatments

Excerpt:

A few months ago, Dr. Thomas Einhorn was treating a patient with a broken ankle that wouldn’t heal, even with multiple surgeries. So he sought help from the man’s own body.

Einhorn drew bone marrow from the man’s pelvic bone with a needle, condensed it to about four teaspoons of rich red liquid, and injected that into his ankle.

Four months later the ankle was healed. Einhorn, chairman of orthopedic surgery at Boston University Medical Center, credits “adult” stem cells in the marrow injection. He tried it because of published research from France.

Einhorn’s experience isn’t a rigorous study. But it’s an example of many innovative therapies doctors are studying with adult stem cells. Those are stem cells typically taken from bone marrow and blood – not embryos.

For all the emotional debate that began about a decade ago on allowing the use of embryonic stem cells, it’s adult stem cells that are in human testing today. An extensive review of stem cell projects and interviews with two dozen experts reveal a wide range of potential treatments.

This is important because embryonic stem cell research involves the destruction of human beings. Real little people that would grow up just like you and me. You have to destroy the embryo in order to get embryonic stem cells.

Adult stem cells used to restore sight to patients blinded by chemical burns

There are two kinds of stem-cell research. The first kind is called embryonic stem-cell research (ESCR). This kind is opposed by pro-lifers because it kills unborn persons by extracting their stem cells for use in medical research. The second kind is called adult stem-cell research (ASCR). This kind is supported by pro-lifers.

You may be surprised to know that ESCR doesn’t work as nearly as well as ASCR.

Excerpt:

Italian scientists report that they have restored sight to patients blinded by chemical burns using the patient’s own adult stem cells. The team treated 112 patients blinded in one or both eyes; some of whom had been blind for years. Adult stem cells were taken from the edge of a patient’s eye and cultured on fibrin, then the cell layers transplanted onto the damaged eyes. The adult stem cells produced healthy corneas and functioning eyes. Some patients regained sight within two months, while for others with deeper injuries the process took a year before vision was restored. Patients were followed up to ten years after the transplant. After a single transplant, 69% of patients regained vision; in some cases a second transplant occurred, with a total success in 77% of patients and partial vision restoration in 13% of patients. The long-term restoration was an especially encouraging success of the study.

Still more cures for adult stem cell research… nothing much for embryonic stem cell research.

FRC is rapidly becoming my second favorite think tank. You would expect them to be social conservatives through and through. But these are not naive fundamentalists – they understand how fiscal policy relates to social policy. Anyone who favors increasing government power to solve social problems, (e.g. – universal health care), is not a social conservative. When a secular government runs huge sectors of the private economy, morality goes out the window. Morality is reduced to claiming a “right” to your neighbors money.
