Plants become green Mr. Clean to combat toxic messes
.... The next big way to clean up toxic sites may be coaxing plants to become janitors, a Michigan State University scientist says. Clayton Rugh, an assistant professor of crop and soil sciences, explains that phytoremediation using plants to remove contaminants from the soil is evolving. In the early stage...Researchers develop new method for facile identification of proteins in bacterial cells
...elaborate conventional sample preparation steps by coaxing the cells into mass production of the protein the researchers wish to analyze. "Finding a specific target in a mixture of hundreds of proteins can be likened to finding the proverbial needle in the haystack; this task can be performed much faster and......ntrolled by -catenin/Wnt signaling are involved in coaxing a dormant stem cell to become active and produce a hair follicle. This study not only provides the best evidence to date to demonstrate this, but it also identifies a group of key genes involved in this crucial activation step."...Jefferson biologist coaxing human embryonic stem cells to make dopamine with simpler, faster method
...re notoriously difficult to use. One problem is in coaxing them into becoming brain cells that make dopamine, which is in short supply in the brains of individuals with Parkinson's. Such cells might be used for transplantation in these patients, but current methods involve extremely complex growth media and ...Sperm stem cells closer to being like embryonic stem cells
... sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body. Researchers at the Cecil H. and Ida Green Center for Reproductive Biology Sciences at UT Southwestern Medical Center devised methods to kee...NJIT engineer poised to take stem cell research a step forward
...ns. So I'd like to regenerate that nerve tissue by coaxing stem cells to turn into neurons. My hope is that in five years, say, a person with spinal cord impairment could visit a doctor and be injected with a supply of stem cells. After such treatment, the patient's spinal cord would begin to heal." Work...Role of the nervous system in regulating stem cells discovered

Bone marrow cells known as hematopoietic stem cells are the source for blood and immune cells. Hematopoietic stem cell transplants are now routinely used to restore the immune systems of patients after int...Discoveries may advance stem cell therapy for Parkinson's, cancer patients

Squier and principal authors Yijia Xiong and Liang Shi, PNNL staff scientists, discovered that the proteins, outer membrane c-type cytochrome A, or OmcA, formed a dense coating on the iron-rich mineral hematite. Th...... fish mends a broken heart may suggest methods for coaxing the damaged hearts of mammals to better heal, researchers report in the November 3, 2006 issue of Cell, published by Cell Press. The researchers found that the hearts of zebrafish harbor progenitor cells that spring into action to restore wounded he...MIT creates 3-D scaffold for growing stem cells
