Hair Regrowth Discovery Suggests Skin Cells Communicate Like Bacteria

Hair Regrowth Discovery Suggests Skin Cells Communicate Like Bacteria | Science, Technology, and Current Futurism | Scoop.it
A chemical signaling system called quorum sensing allows those single-celled bugs to detect when their numbers have multiplied enough to mount an effective attack or emit glowing light. Yet decades after scientists learned about this brainless bacterial coordination a research team has uncovered new evidence suggesting animal cells may speak the same lingo.

Kristala Jones Prather engineers cells to produce useful compounds such as drugs and biofuels.
Sharrock's insight:

excerpt: "“The concept that I was working on was quite simple: Can we take the idea of biocatalysis, of looking at these enzymes and focusing on their chemistry, and combine that with metabolic engineering? Now we are thinking about multistep pathways where we have enzymes working on substrates that they may or may not have seen in nature, and we’re combining them together in a different way so they’re all in one cell,” Prather says."
