Physical vs Biological Signals in Healing

Clinician-scientist Jill Helms is an expert on healing. Until about age 30, people heal easily, she says, but later on, not so well. Regenerative medicine suggests avenues for improvement, she promises. Her research focuses on understanding the physical and molecular processes of healing to design better therapies. One approach awakens “sleeper” stem cells to aid healing, a new drug in trial regenerates bone, and another avenue targets infections that appear near medical devices using gum-like tissues that create sealing barriers. In many ways, nature remains our best model for healing, Helms tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.
