New technology could lead to treatments for osteoarthritis
January 27, 2021 SHARE 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 the diameter of a human hair. When these cells undergo compression, they release the drug that combats inflammation. (Image: Guilak lab)
Working to develop new treatments for osteoarthritis, researchers at Washington University School of Medicine in St. Louis have genetically engineered cartilage to deliver an anti-inflammatory drug in response to activity similar to the bending of a knee or other motions that put stress on joints.
