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 [...]

Let’s look forward a number of years. Bioengineering is at the point where replacing people’s organs with lab-grown ones is standard procedure. Gone are the days of transplant patients taking anti-rejection medications for the rest of their lives. Transplanted organs are all manufactured using stem cells from their own body, from bone marrow or from [...]

University of California, Irvine researchers have identified a gene that is specifically responsible for generating the cerebral cortex, a finding that could lead to stem cell therapies to treat brain injuries and diseases such as stroke and Alzheimer’s.
Dr. Edwin Monuki, doctoral student Karla Hirokawa and their colleagues in the departments of Pathology & Laboratory Medicine [...]

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.
The study represents the first time transplanted embryonic stem cells have been shown to restore function to defective muscles in [...]

The use of a drug to activate stem cells that differentiate into bone appears to cause regeneration of bone tissue and be may be a potential treatment strategy for osteoporosis, according to a report in the February 2008 Journal of Clinical Investigation.
The study – led by researchers from Massachusetts General Hospital (MGH) and the [...]

University of Minnesota researchers have created a beating heart in the laboratory. By using a process called whole organ decellularization, scientists from the University of Minnesota Center for Cardiovascular Repair grew functioning heart tissue by taking dead rat and pig hearts and reseeding them with a mixture of live cells. The research will be published [...]
