Stem cells repair mouse brains post-stroke

Regenerative medicine Peer-Reviewed Publication University of Zurich image: 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 human cells are stained in dark brown. Neurites extend locally into the cortex (CX) but also via […]

Two-part prodrug system activates immune attack only in tumor’s unique environment by University of Cambridge

by University of Cambridge edited by Sadie Harley, reviewed by Robert Egan   Credit: CC0 Public Domain Scientists have developed a smarter way to activate the immune system against cancer, potentially making treatments safer and more precise. The research focuses on a powerful pathway inside our cells known as STING. When triggered, STING acts like an internal alarm

Too soon to tell if ‘liquid biopsies’ help more than harm in cancer screening

by Dennis Thompson edited by Sadie Harley, reviewed by Andrew Zinin “Liquid biopsy” tests using blood samples to screen for multiple types of cancer are attracting much attention, for their potential to catch unseen tumors. But it’s too soon to tell whether they’re truly useful in the fight against cancer, a new evidence review warns. These multicancer
