Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier ...

Jennifer Zenker receives funding from NHMRC and Viertel Foundation. Most people have heard of stem cells. They are often described as “miracle” cells –ones that can grow into any other type of cell in ...

At the turn of the 20th century, Korbinian Brodmann released one of the most consequential brain maps ever. By studying the humps, grooves, layers, and cells of the cortex—the outermost layer of the ...

In a controversial step that raises the possibility of a new kind of infertility treatment, scientists report that they have produced functional human eggs in the lab that were able to be fertilized ...

Brain damage caused by blocked blood vessels may be treatable using injections of stem cells, according to a new study by researchers from the University of Zurich and the University of Southern ...

This image shows a coronal section through the mouse brain after stroke and neural stem cell transplantation. The dashed circle indicates the stroke area. The neurite projections of the transplanted ...
