Ethical Guidelines Presented for Swedish Stem Cell Research
In brief, the guidelines mean that researchers may take stem cells from embryos that can no longer be used for further IVF treatment. Moreover, the creation of embryos by somatic cell nuclear transfer (therapeutic cloning) to get access to stem cells is deemed to be ethically defensible. The reason... view more (2001-12-04)

USC researcher identifies stem cells in tendons that regenerate tissue in animal model
Athletes know that damage to a tendon can signal an end to their professional careers. But a consortium of scientists, led in part by University of Southern California (USC) School of Dentistry researcher Songtao Shi, has identified unique cells within the adult tendon that have stem-cell... view more (2007-09-10)

Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin
In a fundamental discovery that someday may help cure type 1 diabetes by allowing people to grow their own insulin-producing cells for a damaged or defective pancreas, medical researchers here have reported that they have engineered adult stem cells derived from human umbilical cord blood to... view more (2007-05-29)

Sperm stem cells closer to being like embryonic stem cells
New experiments that prevented rat sperm stem cells from changing permanently into 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.   view more (2005-11-16)

Coming soon: Cell therapies for diabetes, cancer?
Therapies using stem cell transplants are advancing promising treatments for such conditions as Alzheimer's Disease, neurological diseases and spinal cord injury, and heart disease.   view more (2008-03-20)

Nerve cells derived from stem cells and transplanted into mice may lead to improved brain treatments
Scientists at the Burnham Institute for Medical Research have, for the first time, genetically programmed embryonic stem (ES) cells to become nerve cells when transplanted into the brain, according to a study published today in The Journal of Neuroscience.   view more (2008-06-25)

Sugar study is sweetener for stem cell science
Scientists at The University of Manchester are striving to discover how the body's natural sugars can be used to create stem cell treatments for heart disease and nerve damage - thanks to a £370,000 funding boost.   view more (2008-07-23)

Mice cloned from skin cells
Healthy and viable mice that survive until adulthood have, for the first time, been cloned from adult stem cells. Scientists from Rockefeller University, including Howard Hughes Medical Institute investigator Elaine Fuchs, used cells called keratinocyte stem cells, which represent a new model... view more (2007-02-13)

Sperm created in the laboratory from embryonic stem cells produce viable progeny
Scientists have demonstrated for the first time that embryonic stem (ES) cells cultured in the laboratory can produce sperm with the capacity to produce viable offspring.   view more (2006-07-12)

Markers of brain cell development may help success of stem cell transplants
Four sugar-coated faces made by stem cells as they differentiate into brain cells during development have been identified by scientists.   view more (2005-09-07)

Johns Hopkins scientists map brain area that may aid hunt for human brain stem cells
A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells.   view more (2006-02-17)

Menstrual blood -- a valuable source of multipotential stem cells?
Researchers seeking new and more abundant sources of stem cells for use in regenerative medicine have identified a potentially unlimited, noncontroversial, easily collectable, and inexpensive source - menstrual blood.   view more (2008-04-23)

Gene silencing directs muscle-derived stem cells to become bone-forming cells
Using a relatively new technology called RNA interference to turn off genes that regulate cell differentiation, University of Pittsburgh researchers have demonstrated they can increase the propensity of muscle-derived stem cells (MDSCs) to become bone-forming cells.   view more (2006-06-02)

Eggs from embryonic stem cells could benefit sterile women
Monash researchers have developed a process that causes embryonic stem (ES) cells to develop into ovarian structures containing eggs.    view more (2005-06-20)

Stem Cells from Hair Follicles May Help
For a rich source of stem cells to be engineered into new blood vessels or skin tissue, clinicians may one day look no further than the hair on their patients' heads, according to new research published earlier this month by University at Buffalo engineers.   view more (2008-03-31)

First for stem cell researcher
In an Australian-first, a UNSW researcher based at the Diabetes Transplant Unit at the Prince of Wales Hospital has produced a human embryonic stem cell (hESC) line without the use of any animal products.   view more (2006-01-23)

Cancer stem cells linked to radiation resistance
Certain types of brain cancer cells, called cancer stem cells, help brain tumors to buffer themselves against radiation treatment by activating a "repair switch" that enables them to continue to grow unchecked.   view more (2006-10-19)

Protein maintains cross talk between cells that control hair growth
Genes, it turns out, are only as active as the signals that turn them on and off. Now scientists from Rockefeller University and the Howard Hughes Institute have identified the signaling molecule that ratchets up and clamps down the activity of key genes in dermal papilla, a type of skin cell whose... view more (2008-02-15)

Researchers make 'embryonic-like' stem cells from umbilical cord blood
A breakthrough in human stem cell research, producing embryonic-like cells from umbilical cord blood may substantially speed up the development of treatments for life-threatening illnesses, injuries and disabilities.   view more (2005-08-18)

Experts discuss use of human stem cells in ape and monkey brains
An expert panel of stem cell scientists, primatologists, philosophers and lawyers has concluded that experiments implanting, or grafting, human stem cells into non-human primate brains could unintentionally shift the moral ground between humans and other primates.   view more (2005-07-15)

Who gives stem cells their marching orders?
Researchers from the Swiss Institute for Experimental Cancer Research (ISREC) have shown that a single gene involved in embryonic development is responsible for two seemingly contradictory activities - maintaining stem cells after the embryo has implanted in the mother's uterus, and later providing... view more (2006-09-06)

Blood stem cells fight invaders, study finds
No other stem cell is more thoroughly understood than the blood, or hematopoietic, stem cell.   view more (2007-11-30)

Dual functions of gene revealed, for better and for worse
Researchers at WEHI have pinpointed the function of a potent cancer gene. The gene, known as "ERG", has long been associated with a range of human malignancies, including leukemia and sarcoma. American scientists showed in 2005 that ERG is mutated in more than half of all prostate... view more (2008-05-27)

Stretching bone marrow stem cells pushes them towards becoming blood vessel
When stretched, a type of adult stem cell taken from bone marrow can be nudged towards becoming the type of tissue found in blood vessels, according to a new study by bioengineers at the University of California, Berkeley.   view more (2006-10-24)

Discovery of good -- and bad -- liver stem cells raises possibility of new treatment
Many scientists believe up to 40 percent of liver cancer is caused by stem cells gone wild - master cells in the organ that have lost all growth control. But, despite years spent looking, no one has ever found these liver "cancer stem cells" - or even normal stem cells in the organ. Until... view more (2008-02-11)
