Researchers develop method of directing stem cells to increase bone formation and bone strength
February 4, 2012 by admin · Leave a Comment
A research team led by UC Davis Health System scientists has developed a novel technique to enhance bone growth by using a molecule which, when injected into the bloodstream, directs the body’s stem cells to travel to the surface of bones. Once these cells are guided to the bone surface by this molecule, the stem cells differentiate into bone-forming cells and synthesize proteins to enhance bone growth. The study, which was published online today in Nature Medicine, used a mouse model of osteoporosis to demonstrate a unique treatment approach that increases bone density and prevents bone loss associated with aging and estrogen deficiency.
USF and Saneron researchers find additional benefits of cord blood cells in mice modeling ALS
Repeated, low-dose injections of mononuclear cells derived from human umbilical cord blood (MNC hUCB, tradename: U-CORD-CELL) have been found effective in protecting motor neuron cells, delaying disease progression and increasing lifespan for mice modeling amyotrophic lateral sclerosis, or ALS, also referred to as Lou Gehrig’s disease, report University of South Florida researchers and colleagues from Saneron CCEL Therapeutics, Inc., and the Ribeirao Preto School of Medicine at the University of Sao Paulo, Brazil.

For the first time ever, stem cells from umbilical cords have been converted into other types of cells, which may eventually lead to new treatment options for spinal cord injuries and multiple sclerosis, among other nervous system diseases.
Scientists learn how stem cell implants help heal traumatic brain injury
January 11, 2012 by admin · Leave a Comment
For years, researchers seeking new therapies for traumatic brain injury have been tantalized by the results of animal experiments with stem cells. In numerous studies, stem cell implantation has substantially improved brain function in experimental animals with brain trauma. But just how these improvements occur has remained a mystery.
New process could advance use of healthy cells or stem cells to treat disease
December 20, 2011 by admin · Leave a Comment
In a discovery that may help speed use of “cell therapy” with normal cells or stem cells infused into the body to treat disease scientists are reporting development of a way to deliver therapeutic human cells to diseased areas within the body using a simple magnetic effect. Their report appears in ACS’ journal Langmuir.

Established human embryonic cell lines, including those approved for federal research funding under former President George W. Bush, are different than newly derived human embryonic stem cell lines, according to a study by UCLA stem cell researchers.
UCLA researchers engineer blood stem cells to fight melanoma
Researchers from UCLA’s cancer and stem cell centers have demonstrated for the first time that blood stem cells can be engineered to create cancer-killing T-cells that seek out and attack a human melanoma. The researchers believe this approach could be useful in 40 percent of Caucasians with this malignancy.
New heart cells increase by 30 percent after stem cell infusion

Healthy, new heart cells have been generated by animals with chronic ischemic heart disease after receiving stem cells derived from cardiac biopsies or “cardiospheres,” according to research conducted at the University at Buffalo School of Medicine and Biomedical Sciences.
Fetal stem cells from placenta may help maternal heart recover from injury
November 13, 2011 by admin · Leave a Comment
Researchers from Mount Sinai School of Medicine have discovered the therapeutic benefit of fetal stem cells in helping the maternal heart recover after heart attack or other injury. The research, which marks a significant advancement in cardiac regenerative medicine, was presented today at the American Heart Association’s (AHA) Scientific Sessions 2011 in Orlando, Florida, and is also published in the current issue of Circulation Research, a journal of the AHA.
