Scientists Progress in Quest to Grow Muscle Tissue in Labs - "The researchers are now working on optimizing the growth of human muscle tissue, including finding a way to get blood flow to the tissue, the best source of cells and the best growing medium for the cells."
Dr. Jörg C. Gerlach has developed a new device for applying a regenerative skin and stem cell slurry onto burn victims in an airbrush-like spray - providing astounding results in mere days. (Warning - mildly graphic images of severe burns being remedied with SCIENCE!)
Claudia Castillo's new bronchus is the result of stem-cell research. The first hollow tube body part is transplanted with no rejection issues. A lab in Italy stripped the donor trachea of living tissue leaving a collagen matrix. Claudia's stem cells were grown in a Bristol lab, (all 6 million of them) to flesh it out, so to speak. Epithelial cells from her nose & lungs formed the lining. But...... [more inside]
Scientists Repurpose Adult Cells - "Scientists have transformed one type of fully developed adult cell directly into another inside a living animal, a startling advance that could lead to cures for a variety of illnesses and sidestep the political and ethical quagmires associated with embryonic stem cell research." [nature abstract, nature writeup, audio announcement]
The FDA has put the brakes on clinical trials of a promising form of stem cell therapy which uses the body's own stem cells to heal dammage. The procedure was used earlier this year to heal the heart of a teenager who was shot in the heart by a nail gun. Other research is being done with the body's own stem cells on the heart and the spinal cord, and new ways to produce large numbers of adult stem cells have been discovered by MIT and the British company TriStem. With the controversy over embryonic stem cells, I'm glad that adult stem cell therapy is showing promise. [Some links via FuturePundit, who is rather annoyed with the FDA.]
Someone else's Religion or your health? How the Catholic church is manipulating medical research in the United States. Stem cell research offers some exciting opportunities for medicine but the Pope doesn't think so.
