Generation of Heart Vessel with Patient’s Own Stem Cells

In the article, “To Fix a Heart, Doctors Train Girl’s Body to Grow New Part,” the Wall Street Journal reported yesterday on an adult stem cell treatment which may revolutionize care of as many as 3,000 children a year. The story focuses on Angela, now 4 years old, who was born with “hypoplastic left heart … Continue reading

High-priced mice for science at Texas A&M

This article from the Texas A&M newspaper describes the medical research with “knockout” mice, or mice that have a specific gene turned off. The  University’s Texas Institute of Genomic Medicine , part of the College of Veterinary Medicine and Biomedical Sciences specializes in developing knockout mice strains using embryonic stem cells from mice embryos, which … Continue reading

Don’t laugh: Nanoparticle rub for impotence

The next addiction? The next big scare? Most definitely the next big joke. What about the man’s sperm? And what about the female partner? How much of a dose will she and her DNA receive. What are nano particles, anyway? (Don’t answer that, I know the text-book answer.) There is a report of a new … Continue reading

>Many Adult Stem Cell Treatments in the News

>This week, we’ve heard about a the new “bandages” for torn knee cartilages and hope for a collagen fibers made using nanotechnology. Animal treatments for joint disease and injury are common in horses and the treatments for dogs are now being advertised by private veterinarians in Oklahoma. The research is ongoing in humans, too. From … Continue reading

>Genes Cut Out of Reprogrammed Cells

>Lots of people (here, here, and here, etc.) are commenting on the “Proof of Concept” by Jaenisch, et. al., in this week’s ScienceExpress (early online publication before print) that showed gene modification to reprogram mouse cells in order to create blood line stem cells that would achieve gene therapy – or even, a cure – … Continue reading

>Flash: Embryonic tissue more difficult to obtain than adult

> This could liberate future researchers from relying on embryonic tissue, which can be more difficult to acquire. “NatureNews,” the news alert website for the journal Nature, has a news report (registration required) on a study published in the December 6 issue of the journal by researchers from Bonn, New York, Rhode Island, and Pennsylvania … Continue reading

>Wash this reactionary’s mouth out with soap!

> compares the Bush administration’s happiness about reprogrammed adult stem cells with that man, Mr. Clinton’s, “I did not have sex with that woman!” and President Bush’s statement “Mission accomplished,” after our US troops captured Baghdad. I’ll accept the latter (at some future date, if the evidence supports it), but the first is at least … Continue reading

Dolly’s Dad: Cloning, embryos and eggs not needed

10 years after the world learned about the cloning of Dolly the sheep, the scientist responsible for her birth announces that cloning is passe’. Just after the announcement that a US lab has managed the first confirmed cloning of primate (monkeys, not human) embryos using adult cell donor DNA, Ian Wilmut made statements to the … Continue reading

>"Exaggerated resistance" (Or how not to report science)

>Scientific American gives us several reasons to “resist” the information in its pages this month, the August, 2007 issue. Unfortunately, only the Table of Contents is free, but the problem is in the titles given “news” stories themselves. Under the title, “Roots of Science Hatred,” on page 29 we learn that people learn to trust … Continue reading

Don’t bet on cloning to cure

Ian Wilmut says that if he had “to bet money,” he’d bet on reprogramming adult – the patient’s own stem cells. Joining the cloning experts in the race are scientists who are looking for new ways to “reprogram” DNA, or make it young again without fusing it into an egg. They think it may be … Continue reading
