Gene directs stem cells to build the heart (7/5/2008)

Researchers have shown that they can put mouse embryonic stem cells to work building the heart, potentially moving medical science a significant step closer to a new generation of heart disease treatments that use human stem cells. ...> Full Article

Saving teeth by using periodontal ligament regeneration (6/6/2008)

3D in vitro model appears to be promising for regenerating periodontal ligament and may also prove valuable for restoring tendons and ligaments elsewhere in the body. ...> Full Article

Biomedical Engineers Develop Living Heart Chambers for Study of Cardiac Function and Repair (5/25/2008)

Researchers have developed tiny functioning heart chambers that exhibit the key characteristics of cardiac pumping action. These modified tissue samples, known as organoids, will enable researchers to far more easily study heart growth and development, as well as provide a novel means for evaluating new treatments for diseased or damaged cardiac tissue. ...> Full Article

New role found for a cardiac progenitor population (5/15/2008)

In a discovery that could one day lead to an understanding of how to regenerate damaged heart tissue, researchers have found that parent cells involved in embryonic development of the epicardium - the cell layer surrounding the outside of the heart - give rise to three important types of cells with potential for cardiac repair. ...> Full Article

Researchers control growth rate of replacement blood vessels, tissues (3/9/2008)

Researchers have discovered a way to control the growth rate of replacement tissue and the formation of new blood vessels, which solves one of the vexing problems of growing replacement tissue to treat injuries and trauma in humans. ...> Full Article

From Stem Cells To Organs: The Bioengineering Challenge (2/17/2008)

For more than a decade, Peter Zandstra has been working at the University of Toronto to rev up the production of stem cells and their descendants. The raw materials are adult blood stem cells and embryonic stem cells. The end products are blood and heart cells -- lots of them. Enough mouse heart cells that they form beating tissue. ...> Full Article

Adult Stem Cells Beneficial in Heart Failure Recovery (1/26/2008)

A study in the Clinical and Experimental Pharmacology and Physiology published by Wiley-Blackwell shows that administration of adult bone marrow stem cells (BMC) and mesenchymal stems cells (MSC) can aid in the recovery of myocardial infarction (MI) - commonly known as heart attack - and consequently increase survival rates. ...> Full Article

First U.S. Trial Transplants Stem Cells to Investigate Prevention of Leg Amputations (1/23/2008)

A Northwestern University Feinberg School of Medicine researcher has launched the first U.S. trial in which a purified form of subjects' own adult stem cells was transplanted into their leg muscles with severely blocked arteries to try to grow new small blood vessels and restore circulation in their legs. ...> Full Article

Stem-cell Transplantation Improves Muscles In Muscular Dystrophy Animal Model, Researchers Report (1/21/2008)

Using embryonic stem cells from mice, UT Southwestern Medical Center researchers have prompted the growth of healthy -- and more importantly, functioning -- muscle cells in mice afflicted with a human model of Duchenne muscular dystrophy. ...> Full Article

Researchers identify mechanism that controls activation of stem cells during hair regeneration (1/17/2008)

Researchers at the University of Southern California have identified a novel cyclic signaling in the dermis that coordinates stem cell activity and regulates regeneration in large populations of hairs in animal models. The signaling switch involves bone morphogenetic protein (Bmp) pathway, according to the study that will be published in the Jan. 17 issue of the journal Nature. ...> Full Article

Protein in Human Hair Shows Promise for Regenerating Nerves (1/11/2008)

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. ...> Full Article

Scientists Invent Novel Hydrogels For Repairing And Regenerating Human Tissue (7/21/2007)

University of Delaware scientists have invented a novel biomaterial with surprising antibacterial properties that can be injected as a low-viscosity gel into a wound where it rigidifies nearly on contact - opening the door to the possibility of delivering a targeted payload of cells and antibiotics to repair the damaged tissue. ...> Full Article
