Researchers Create Model of Anorexia Nervosa Using Stem Cells

An international research team, led by scientists at University of California San Diego School of Medicine, has created the first cellular model of anorexia nervosa (AN), reprogramming induced pluripotent stem cells (iPSCs) derived from adolescent females with the eating disorder.

Study Identifies Molecular Clues for Age-Related Intestinal Issues

Geiger_CellReports_Intestine1EXT.jpg

Intestinal stem cells rejuvenate daily so bowels will stay healthy and function normally, but a new study in Cell Reports suggests they also age along with people and lose their regenerative capacity. Reporting their data online March 14, researchers suggest that reactivating the signaling of a key molecule lost in aging intestinal stem cells could restore healthy intestinal function in older people.

Targeting Cancer Stem Cells Improves Treatment Effectiveness and Prevents Metastasis

Targeting cancer stem cells may be a more effective way to overcome cancer resistance and prevent the spread of squamous cell carcinoma — the most common head and neck cancer and the second-most common skin cancer, according to a new study by cancer researchers at the UCLA School of Dentistry. Head and neck squamous cell carcinoma is a highly invasive form of cancer and frequently spreads to the cervical lymph nodes.

NIH-Funded Study Helps Explain How Zebrafish Recover From Blinding Injuries

Researchers at Vanderbilt University in Nashville, Tennessee have discovered that in zebrafish, decreased levels of the neurotransmitter gamma-aminobutyric acid (GABA) cue the retina, the light-sensing tissue in the back of the eye, to produce stem cells. The finding sheds light on how the zebrafish regenerates its retina after injury and informs efforts to restore vision in people who are blind.

Cedars-Sinai Neuroscientists Pinpoint Key Gene Controlling Tumor Growth in Brain Cancers

Cedars-Sinai investigators have identified a stem cell-regulating gene that affects tumor growth in patients with brain cancer and can strongly influence survival rates of patients. The findings, published in the online edition of Nature Scientific Reports, could move physicians closer to their goal of better predicting the prognosis of patients with brain tumors and developing more personalized treatments for them.

New Method Rescues Donor Organs to Save Lives

Researchers from Columbia Engineering and Columbia University Medical Center have—for the first time—maintained a fully functional lung outside the body for several days. They designed the cross-circulation platform that maintained the viability and function of the donor lung and the stability of the recipient over 36-56 hours, used the advanced support system to fully recover the functionality of lungs injured by ischemia and made them suitable for transplant.

Scientists Wage Fight Against Aging Bone Marrow Stem Cell Niche

Geiger_EMBO_BoneMarrowEXT.jpg

As people get older so do the hematopoietic stem cells (HSCs) that form their blood, creating an increased risk for compromised immunity and certain blood cancers. Now researchers are reporting in the scientific journal EMBO that the bone marrow niche where HSC’s form also ages, contributing to the problem. In a study published March 2, scientists in Germany and the United States propose rejuvenating the bone marrow niche where HSCs are created.
