Zuo C, Wang L, Kamalesh RM, Bowen ME, Moore DC, Dooner MS, Reginato AM, Wu Q, Schorl C, Song Y, Warman ML, Neel BG, Ehrlich MG, Yang W.
PMID: 29644115

Chondrocytes and osteoblasts differentiate from a common mesenchymal precursor, the osteochondroprogenitor (OCP), and help build the vertebrate skeleton. The signaling pathways that control lineage commitment for OCPs are incompletely understood. We asked whether the ubiquitously expressed protein-tyrosine phosphatase SHP2...

BACKGROUND: Several fixation methods have been reported for the operative treatment of tibial eminence fractures. Previous biomechanical studies have demonstrated that suture fixation may be a stronger construct; however, the maturity status of these specimens was not scrutinized.PURPOSE: To...

Enrichment of inflammatory mediators in the synovial fluid is associated with slower progression of mild to moderate osteoarthritis in the porcine knee.

American journal of translational research

Karamchedu NP, Fleming BC, Donnenfield JI, Proffen BL, Costa MQ, Molino J, Murray MM.
