Scientists Say the Brain Is Two Organs, Not One

Stanford researchers traced two separate progenitor cells in mouse embryos, one wiring up the thinking brain and the other the life support system of breathing and heartbeat, explaining why hindbrain neurons have been nearly impossible to grow in a lab.

The Immune Cell That Could Make CAR Macrophage Therapy Renewable

Engineered macrophages struggle to expand and persist as cancer therapies. USC researchers found a way to grow their upstream progenitors on a massive scale by blocking one enzyme. CAR-engineered versions attacked leukemia and solid tumors in mice. A new receptor design even recruited the host’s immune system across mismatch barriers.
