Case Western Reserve Researcher Outlines Road Map for Addressing Ethical Concerns Tied to Research on Combination Human-Animal Embryos

Insoo Hyun has proposed a framework for addressing ethical questions surrounding potentially revolutionary research on part-human, part-animal embryos, which can be produced when human stem cells are transplanted into animal embryos.

Researchers at University of California San Diego School of Medicine and Moores Cancer Center have identified RNA-based biomarkers that distinguish between normal, aging hematopoietic stem cells and leukemia stem cells associated with secondary acute myeloid leukemia (sAML), a particularly problematic disease that typically afflicts older patients who have often already experienced a bout with cancer.

A new biomaterial can be used to study how and when stem cells sense the mechanics of their surrounding environment. With further development, this biomaterial could be used to control when immature stem cells differentiate into more specialized cells for regenerative and tissue-engineering-based therapies.

New Research Reveals Cancers Need a 'Perfect Storm' of Conditions to Develop

122493_web.jpg

SCIENTISTS have demonstrated for the first time the 'perfect storm' of conditions that cells need to start forming cancer, helping to explain why some organs are more susceptible to developing the disease, according to a new study published in Cell today (Thursday).

Study Shows Protein Complex Essential to Creating Healthy Blood Cells

A group of proteins best known for helping to activate all mammalian genes has been found to play a particularly commanding role in the natural development of specialized stem cells into healthy blood cells, a process known as hematopoiesis.

Neural Stem Cells Control Their Own Fate

122130_web.jpg

To date, it has been assumed that the differentiation of stem cells depends on the environment they are embedded in. A research group at the University of Basel now describes for the first time a mechanism by which hippocampal neural stem cells regulate their own cell fate via the protein Drosha. The journal Cell Stem Cell has published their results.
