Tiny Biobots Surprise Their Creators by Healing Wound
6th January 2025
Tiny “biobots” made from human windpipe cells encouraged damaged neural tissue to repair itself in a lab experiment — potentially foreshadowing a future in which creations like this patrol our bodies, healing damage, delivering drugs, and more.
The background: In a study published in 2020, researchers at Tufts University and the University of Vermont (UVM) harvested and incubated skin cells from frog embryos until they were tiny balls.
They then sculpted the spheres into specific shapes — dictated by an algorithm — and added layers of cardiac stem cells to them in precise locations.
