Lubricin Therapy &

Lubricin, also called proteoglycan 4 (PRG4), is a sugar-rich proteoglycan that enables low-friction cartilage lubrication and promotes joint health.  Current efforts focus on investigating the safety and efficacy of recombinant lubricin and lubricin-inspired therapeutics for osteoarthritis.
