Regenerative medical techniques hold great promise for bladder regeneration

Bladder regeneration via a neo-bladder replacement may prove to be effective in humans. The results of a new study, conducted in large mammals, presented today at the 103rd Annual Scientific Meeting of the American Urological Association (AUA), suggest that this process could result in a regenerated bladder with similar characteristics of the native bladder and without the risks associated with a donated organ or other undesirable outcomes associated with current surgical interventions.

Menstrual blood, valuable source of multipotential stem cells?

Protein protects embryonic stem cells' versatility and self-renewal

A protein known as REST blocks the expression of a microRNA that prevents embryonic stem cells from reproducing themselves and causes them to differentiate into specific cell types, scientists at The University of Texas M. D. Anderson Cancer Center report in the journal Nature.

Protein in human hair shows promise for regenerating nerves

A protein found in human hair shows promise for promoting the regeneration of nerve tissue and could lead to a new treatment option when nerves are cut or crushed from trauma.

Mechanism for regulation of growth, differentiation of muscle stem cells is revealed

During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue.

Embryonic stem cells used to grow cartilage

Rice University biomedical engineers have developed a new technique for growing cartilage from human embryonic stem cells, a method that could be used to grow replacement cartilage for the surgical repair of knee, jaw, hip, and other joints.

Engineered Blood Vessels Function like Native Tissue

Blood vessels that have been tissue-engineered from bone marrow adult stem cells may in the future serve as a patient's own source of new blood vessels following a coronary bypass or other procedures that require vessel replacement, according to new research from the University at Buffalo Department of Chemical and Biological Engineering.

5 genetic themes key to keeping stem cells in flexible state

harminka — Wed, 20 Jun 2007 06:28:17 -0500

For more than 25 years, stem cells have been defined based on what they can become: more of themselves, as well as multiple different specialized cell types. But as genetic techniques have become increasingly powerful, many scientists have sought a more molecular definition of stem cells, based on the genes they express.

Finding ways to preserve human eggs, ovarian tissue under way

The goal is to make human eggs, ovarian tissue, blood vessels, even whole organs available when needed.

Scientists make major breakthrough in regenerative medicine

harminka — Tue, 24 Apr 2007 12:17:11 -0500

Findings described in a new study by Stanford scientists may be the first step toward a major revolution in human regenerative medicine-a future where advanced organ damage can be repaired by the body itself. In the May 2007 issue of The FASEB Journal, researchers show that a human evolutionary ancestor, the sea squirt, can correct abnormalities over a series of generations, suggesting that a similar regenerative process might be possible in people.
