Abstract
The present invention provides a meniscus regeneration material having high meniscus regeneration ability. The meniscus regeneration material includes protein (A), which has a total percentage of β-turns and random coils of 60 to 85% as determined by circular dichroism spectroscopy, and the meniscus regeneration material may further include meniscus tissue fragment (B). The present invention also provides the use of the meniscus regeneration material for promoting meniscus regeneration and treating meniscus damage, cartilage defects, or osteoarthritis.
