Tulane professor receives grant to improve stem cell survival

Credit: TulaneKim O’Connor, a professor in Tulane University’s Department of Chemical and Biomolecular Engineering, received a three-year $599,638 grant from the National Science Foundation to study w..

New procedure allows long-term culturing of adult stem cells

A new procedure developed at Massachusetts General Hospital (MGH) may revolutionize the culturing of adult stem cells. In their report that has been published online prior to its appearance in the Aug..

Penn-led study resolves long-disputed theory about stem cell populations

Adult stem cells represent a sort of blank clay from which a myriad of different cell and tissue types are molded and as such are of critical importance to health, aging and disease. In tissues that t..

Neural stem cell transplants promote Parkinson’s recovery in non-human primates

Human parthenogenetic stem cells, derived from unfertilized oocytes, can be used without destroying potentially viable human embryos to generate unlimited supply of neural stem cells for transplantati..

Gut microbes’ metabolite dampens proliferation of intestinal stem cells

Intestinal stem cells are among the most rapidly dividing cells in the body, busily creating new cells to replace the ones that are constantly being sloughed off. But unlike stem cells elsewhere in th..

Stem cells from diabetic patients coaxed to become insulin-secreting cells

Signaling a potential new approach to treating diabetes, researchers at Washington University School of Medicine in St. Louis and Harvard University have produced insulin-secreting cells from stem cel..

Penn bioengineers show why lab-made stem cells might fail: Errors in DNA folding

Induced pluripotent stem cells hold promise for regenerative medicine because they can, in theory, turn into any type of tissue and because they are made from a patient’s own adult cells, guaranteeing..

Two known chemotherapy agents effectively target breast cancer stem cells

AUGUSTA, Ga. – Two existing chemotherapy drugs appear to be a powerful pair in targeting errant stem cells that are making breast cancer and enabling its spread and recurrence, scientists report. A c..

Stem cells used to successfully regenerate damage in corticospinal injury

Writing in the March 28, 2016 issue of Nature Medicine, researchers at University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System, with colleagues in Japan..

Handheld surgical ‘pen’ prints human stem cells

In a landmark proof-of-concept experiment, Australian researchers have used a handheld 3D printing pen to ‘draw’ human stem cells in freeform patterns with extremely high survival rates. The device,..

UCI study finds safer stem cell-derived therapy for brain radiation recovery

Irvine, Calif., April 7, 2016 — While stem cells have shown promise for treating brain regions damaged by cancer radiation treatments, University of California, Irvine researchers have found that micr..

‘Hydrogels’ boost ability of stem cells to restore eyesight and heal brains

Scientists and engineers have made a breakthrough in cell transplantation using a gel-like biomaterial that keeps cells alive and helps them integrate better into tissue. In two early lab trials, this...

Dead feeder cells support stem cell growth

Stem cells naturally cling to feeder cells as they grow in petri dishes. Scientists have thought for years that this attachment occurs because feeder cells serve as a support system, providing...

Beyond genes: are centrioles carriers of biological information?

EPFL scientists discover that certain cell structures, the centrioles, could act as information carriers throughout cell generations. The discovery raises the possibility that transmission of biological information could involve more than...
