CHINA – Stem cells. Infinite source of eggs found

Image via Wikipedia

An extremely valuable source of eggs has been discovered in female mice. The discovery was described as a potentially infinite source of female fertility, or germline stem cells, which can continue producing new egg cells in adults, which could be a cure for sterility and menopause.
The discovery was made by Ji Wu of the University of Shanghai Jiao Tong and contradicts previous research on the female reproductive system, possibly paving the way for new prospects to treat sterility and revolutionize female reproduction, which after menopause could make use of germline stem cells that were previously isolated

Israeli researchers discover method to neutralize tumor growth in embryonic stem cell therapy

Hebrew University of Jerusalem

Researchers at the Hebrew University of Jerusalem discovered a method to potentially eliminate the tumor-risk factor in utilizing human embryonic stem cells, said the university on Wednesday.
The researchers’ work paves the way for further progress in the promising field of stem cell therapy, said the press release of the university sent to Xinhua.

According to the release, human embryonic stem cells are theoretically capable of differentiation to all cells of the mature human body (and are hence defined as “pluripotent“).
This ability, along with the ability to remain undifferentiated indefinitely in culture, make regenerative medicine using human

USA – Umbilical Cord Stem Cells Increasingly Stored in Private Banks for Autologous Use

Stem cells from umbilical cords are increasingly being stored in private banks for autologous use. “Newsweek” added to the debate writing about Dallas Hextell, who at the age of  8 months  was diagnosed with cerebral paralysis, a condition normally caused by serious neural damage due to oxygen deprivation in the uterus or at birth. His parents consulted various neurologists, but the possibility of a recovery was virtually non-existant.

About 9 months later, when given the opportunity to participate in a Duke University clinical study on autologous stem cell transplants (stem cells that are stored for later use by

Grant money could speed stem cell cures

Dr. Karen Aboody estimates that she has cured several hundred mice of a cancer of the central nervous system called neuroblastoma.
First she injected them with specialized neural stem cells that naturally zero in on the tumors and surround them. Then she administered an anti-cancer agent that the cells converted into a highly toxic drug (…)

For 3 1/2 years, the agency focused on the basic groundwork needed to someday use human embryonic stem cells to replace body parts damaged by injury or disease. Such cures are still far in the future.
Now the institute has a more immediate goal: boosting therapies

New Hope For Kidney Disease Patients from Stem Cells

Several cell-based therapy approaches could provide new treatments for patients with Alport syndrome, reports an upcoming paper in the Journal of the American Society of Nephrology.

“Our study opens up many considerations of how new therapies related to the use of stem cells can be devised for our kidney patients with chronic disease,” comments Raghu Kalluri, MD, PhD (Harvard Medical School, Boston, MA) (…)

The experiments provide evidence that stem cell treatments could repair the kidney defects associated with Alport syndrome. “We found that stem cells derived from adult bone marrow are equally useful as embryonic stem cells,” says
