New Lab-Grown Lip Cells Could Transform Research and Treatment for Disfiguring Lip Conditions

We use our lips to talk, eat, drink, and breathe; they signal our emotions, health, and aesthetic beauty. It takes a complex structure to perform so many roles, so lip problems can be hard to repair effectively. Basic research is essential to improving these treatments, but until now, models using lip cells -; which perform differently to other skin cells -; have not been available.
