Always a good call out, but also:

> Human knee tissue collected during joint replacement surgeries also responded positively to the treatment. These samples, which include both the joint’s supporting extracellular scaffolding, or matrix, and cartilage-producing chondrocyte cells, began forming new cartilage that functioned normally.

Good, but what does it mean for tissue samples to function normally? Function as what?
