US plays Catch Up with clinical trials for Diabetes type 1 and congestive heart failure

In ALL ARTICLES on August 15, 2009 at 3:23 pm

The Food and Drug Administration cleared a Phase I Clinical Trial to treat congestive heart failure using stem cells from the patients’ own thigh muscles. In another major story, the Juvenile Diabetes Research Foundation awarded $750,000 to scientists making progress evaluating adult stem cell therapy for Type I diabetes.

How sad that New Yorkers pay for patients to wait for some possible future treatment requiring human embryos while progress using ethical stem cells continues in other states. These states will attract patients and professionals establishing careers in cutting-edge medicine.

Some mice stem cells divide in unexpected ways

Professor Tudorita Tumbar, professor of molecular biology and genetics, uses fluorescence microscopy to study stem cells in a tissue environment.

Using new genetic tools, Cornell researchers have found that some stem cells in mice behave dramatically different than in fruit flies, where most of the pioneering stem cell work has been conducted. The findings could have important implications for understanding how some cancers might be initiated, say the researchers.

…The prevailing evidence for fruit flies (Drosophila) shows that normal adult stem cells generate two daughter cells with different fates; one becomes another stem cell, and the other becomes a differentiated cell with a fixed number of cell divisions left in its life. This is called an “asymmetric fate decision” because the daughter cells do not have identical fates.

The new study, published online Aug. 6 in the journal Cell Stem Cell, indicates that dividing hair follicle stem cells in adult mice, on the other hand, can undergo symmetric fates — the daughter cells can both become either stem cells or differentiated cells.

The study is among the first to consider directly how dividing stem cells choose their fate in undamaged mouse tissues. The findings imply that certain previously held assumptions about stem cell behavior in mammals may not be applicable to stem cells in all organ systems…

Missy Lucero hugs here godson, Angel. She hopes that her adult stem cell treatment is successful so she can raise him to adulthood.

…when hypertension affects the blood vessels of the lungs, it can go from bad to worse rapidly. The disease acts rather like a kinked garden hose, increasing pressure and back up. It involves three processes: Vasoconstriction, a narrowing of the blood vessels; scarring of the blood vessels causing thickening and stiffening which narrows them further and may lead to complete blockage, and thrombosis or clotting.

It becomes progressively more difficult for blood to get through to the lungs. As a result, the right side of the heart is forced to pump harder to force blood through; the stress enlarges the heart and makes it less flexible. Less blood flows through the lungs and on to the rest of the body. Patients become tired, light headed and short of breath at the slightest exertion. There is no known cure, yet.

Clinical trials at the Mayo Clinic in Florida have seen successes in reversing and curing pulmonary hypertension using adult stem cells from patients’ own blood….

Payment to cull ovum is unethicalEssays – August 15, 2009 – 3:00am

The Empire State Stem Cell Board approved compensation for women who “donate” their ovum to the tune of $10,000 per cycle. The board, which overwhelming supports human embryo research, was created through a funding allocation buried in a 2006 spending bill and serves at the pleasure of the governor.

New York State stands alone in its plan to give money to women who undergo ovarian hyper-stimulation and surgery to cull their eggs. Embryonic stem cell researchers, not satisfied using leftover embryos, need money directed to women because few will volunteer for medically invasion procedures with unknown consequences.

As unethical as that proposition is, we really do know a lot about the risks of egg harvesting. Women undergoing ovarian hyper-stimulation for infertility treatment suffer side effects from mood changes to increased risks of stroke and death.

Who among us is not aware of the risks of anesthetic? Every invasive procedure increases susceptibly to antibiotic resistant infections.Consider who will accept $10,000 to sell eggs. It won’t be educated women.

The vulnerable woman, for whom $10,000 represents a huge amount of money, will be targetedPayment for eggs is an outrageous plan to exploit women’s bodies, objectionable in itself.
