‘Smart’ cartilage cells programmed to release drugs when stressed

by  Washington University School of Medicine Researchers at Washington University School of Medicine in St. Louis have engineered cartilage cells to release an anti-inflammatory drug in response to stresses such cells undergo when they are compressed during weight bearing and movement. Here, the cell, called a chondrocyte, is stimulated with a very small glass pipette, about 1/5...
