Using Bone Marrow to Protect the Brain: Stem Cell Technology Begins Clinical Trial for Lou Gehrig's Disease PDF Print E-mail
Saturday, 24 September 2011 00:40
The ability to produce neuroprotectors, proteins that protect the human brain against neurodegenerative disorders such as Parkinson's and ALS, is the holy grail of brain research. A technology developed at Tel Aviv University does just that, and it's now out of the lab and in hospitals to begin clinical trials with patients suffering from amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease.
Stem Cells, Potential Source of Cancer-Fighting T Cells PDF Print E-mail
Saturday, 24 September 2011 00:27
Adult stem cells from mice converted to antigen-specific T cells -- the immune cells that fight cancer tumor cells -- show promise in cancer immunotherapy and may lead to a simpler, more efficient way to use the body's immune system to fight cancer, according to Penn State College of Medicine researchers.
Stem Cell: Gene Therapy Destroys Type Of Cancer Cell PDF Print E-mail
Thursday, 22 September 2011 00:49

Gene therapy delivered directly to a breast cancer stem cell causes the cell to self-destruct, lowering recurrence risk, U.S. researchers say.

New Class of Stem Cell-Like Cells Discovered Offers Possibility for Spinal Cord Repair PDF Print E-mail
Tuesday, 20 September 2011 00:38
The Allen Institute for Brain Science has announced the discovery of a new class of cells in the spinal cord that act like neural stem cells, offering a fresh avenue in the search for therapies to treat spinal cord injury and disease.
Genomic Catastrophe Causes Developmental Delay, Cognitive Disorders PDF Print E-mail
Tuesday, 20 September 2011 00:13
Using a diversity of DNA sequencing and human genome analytic techniques, researchers led by Baylor College of Medicine have identified some cases of developmental delay or cognitive disorders associated with a sudden chromosomal catastrophe that occurred early in development, perhaps during cell division when DNA is replicated.
Shaping Up: Controlling a Stem Cell's Form Can Determine Its Fate PDF Print E-mail
Saturday, 17 September 2011 00:38
"Form follows function!" was the credo of early 20th century architects making design choices based on the intended use of the structure. Cell biologists may be turning that on its head.
Gene Therapy Kills Breast Cancer Stem Cells, Boosts Chemotherapy PDF Print E-mail
Thursday, 15 September 2011 00:49
Gene therapy delivered directly to a particularly stubborn type of breast cancer cell causes the cells to self-destruct, lowers chance of recurrence and helps increase the effectiveness of some types of chemotherapy, researchers at The University of Texas MD Anderson Cancer Center reported in the Sept. 13 edition of Cancer Cell.
Critical Similarity Found Between Two Types of Do-It-All Stem Cells PDF Print E-mail
Thursday, 15 September 2011 00:15
Ever since human induced pluripotent stem cells were first derived in 2007, scientists have wondered whether they were functionally equivalent to embryonic stem cells, which are sourced in early-stage embryos.
Scientists Successfully Expand Bone Marrow-Derived Stem Cells in Culture PDF Print E-mail
Tuesday, 13 September 2011 00:30
All stem cells -- regardless of their source -- share the remarkable capability to replenish themselves by undergoing self-renewal. Yet, so far, efforts to grow and expand scarce hematopoietic (or blood-forming) stem cells in culture for therapeutic applications have been met with limited success.
Metabolic State of Brain Cancer Stem Cells Significantly Different Than the Cancer Cells They Create PDF Print E-mail
Saturday, 10 September 2011 00:56
The metabolic state of glioma stem cells, which give rise to deadly glioblastomas, is significantly different from that of the brain cancer cells to which they give birth, a factor which helps those stem cells avoid treatment and cause recurrence later.
Scientists Turn Back the Clock On Adult Stem Cells Aging PDF Print E-mail
Saturday, 24 September 2011 00:37
Researchers have shown they can reverse the aging process for human adult stem cells, which are responsible for helping old or damaged tissues regenerate. The findings could lead to medical treatments that may repair a host of ailments that occur because of tissue damage as people age.
HPD Saving Lives Through Stem Cell Donations PDF Print E-mail
Thursday, 22 September 2011 00:52

Cancer patients who need a stem cell transplant often wait months or years for a match. Sometimes, it never happens. But Houston police officers have taken up the cause.

In just a couple years, Houston Police Department officers have saved more cancer patients than anyone thought possible.

Stem Cells Used To Treat Pets PDF Print E-mail
Thursday, 22 September 2011 00:47
Some ailing pets are getting help from their body's own stem cells, thanks to scientific progress.

Western Veterinary Clinic on Monday removed a small bit of fat from the abdomen of Arrow, a 12-year-old golden retriever who has hip dysplasia and arthritis.
Switch That Controls Stem Cell Pluripotency Discovered PDF Print E-mail
Tuesday, 20 September 2011 00:18
Scientists have found a control switch that regulates stem cell "pluripotency," the capacity of stem cells to develop into any type of cell in the human body. The discovery reveals that pluripotency is regulated by a single event in a process called alternative splicing.
Protein Prompting Cells To Sprout Legs Could Cause Skin Cancer To Spread PDF Print E-mail
Saturday, 17 September 2011 00:43

Cancer Research UK scientists have discovered that a protein called Rac1 prompts pigment cells to sprout long ‘legs’ that could propel skin cancer cells, allowing them to spread, according to research published in Developmental Cell today.

Uterine Stem Cells Used to Treat Diabetes PDF Print E-mail
Saturday, 17 September 2011 00:35
Controlling diabetes may someday involve mining stem cells from the lining of the uterus, Yale School of Medicine researchers report in a new study published in the journal Molecular Therapy. The team treated diabetes in mice by converting cells from the uterine lining into insulin-producing cells.
Fish Oil Reduces Effectiveness of Chemotherapy PDF Print E-mail
Thursday, 15 September 2011 00:18

It now appears that chemotherapy is made ineffective by two types of fatty acid that are made by stem cells in the blood. Under the influence of cisplatin chemotherapy, the stem cells secrete these fatty acids that induce resistance to a broad spectrum of chemotherapies.

Exercise Boosts Health by Influencing Stem Cells to Become Bone, Not Fat, Researchers Find PDF Print E-mail
Tuesday, 13 September 2011 00:59
McMaster researchers have found one more reason to exercise: working out triggers influential stem cells to become bone instead of fat, improving overall health by boosting the body's capacity to make blood.
‘Stem Cell Zoo’ To Save Endangered Species PDF Print E-mail
Tuesday, 13 September 2011 00:02
Science is advancing yet again, with the focus now on saving endangered species through what researchers call a “stem cell zoo.” This “zoo” houses the stem cells of only two animals — the critically endangered drill primate and white rhino — so far, but will hopefully expand to contain those of all endangered animals.
Ultrasound Improves Stem Cell Transplants, Swedish Researchers Discover PDF Print E-mail
Saturday, 10 September 2011 00:56
Transplantation of hematopoietic stem cells is an effective treatment for patients with malignant blood diseases. The composition and quality of the transplanted cells are crucial to the outcome. Researchers from Lund University, Sweden, have now developed a method to improve the quality of the transplanted cells using ultrasound for cell separation.
