UCLA Scientists Identify Cell and Signaling Pathway that Regulates the Placental Blood Stem Cell Niche

University of California, Los Angeles (UCLA), Health Sciences

UCLA stem cell researchers have discovered a critical placental niche cell and signaling pathway that prevent blood precursors from premature differentiation in the placenta, a process necessary for ensuring proper blood supply for an individual’s lifetime.

Molecule's Role in Cancer Suggests New Combination Therapy

University of Illinois at Chicago

Researchers at the University of Illinois at Chicago College of Medicine have found that a molecule found at elevated levels in cancer cells seems to protect them from the "cell-suicide" that is usually triggered by chemotherapy or radiation.

New Pattern Identifies Cells That Pose Risk of Tumors in Gonadal Dysgenesis Patients

Allen Press Publishing

Pediatric and Developmental Pathology – Gonadal dysgenesis—defective development of the ovaries or testes— may also bring with it an increased risk of gonadal tumors. A recent discovery at the histologic level could help identify cells at risk of conversion into a tumor. For patients with XY gonadal dysgenesis, this means earlier detection and treatment of tumors.

A Surprising Molecular Switch Lipids Help Control the Development of Cell Polarity.

Stowers Institute for Medical Research

In a standard biology textbook, cells tend to look more or less the same from all sides. But in real life cells have fronts and backs, tops and bottoms, and they orient many of their structures according to this polarity explaining, for example, why yeast cells bud at one end and not the other.

UCLA Discovery that Migrating Cells "Turn Right' has Implications for Engineering Tissues, Organs

University of California, Los Angeles (UCLA), Health Sciences

What if we could engineer a liver or kidney from a patient's own stem cells? How about helping regenerate tissue damaged by diseases such as osteoporosis and arthritis? A new UCLA study bring scientists a little closer to these possibilities by providing a better understanding how tissue is formed and organized in the body.
