Stanford study finds blocking aging-related protein restores knee cartilage in mice and human tissue
A weekday bagel. Dependable, satisfying, no fuss.
Summary
Stanford Medicine researchers have discovered that blocking a protein linked to aging can restore lost knee cartilage in older mice and prevent arthritis after joint injuries. Human cartilage samples from knee replacement surgeries also showed regeneration when exposed to the treatment. The findings suggest a potential future drug—either an injection or oral medication—that could repair damaged joints instead of requiring replacement surgery.
Key quotes
· 3 pulledA treatment that targets a protein linked to aging has restored lost knee cartilage in older mice and prevented arthritis from developing after serious joint injuries, according to a Stanford Medicine-led study.
Samples collected during knee replacement surgeries began producing new, functional cartilage when exposed to the treatment.
The findings raise the possibility that damaged cartilage caused by aging or osteoarthritis could one day be repaired with either a local injection or an oral medication.
