Periodic Mechanical Stress INDUCES Chondrocyte Proliferation and Matrix Synthesis via CaMKII-Mediated Pyk2 Signaling

Cellular Physiology and Biochemistry, 2017
Background/Aims: Periodic mechanical stress can promote chondrocyte proliferation and matrix synthesis to improve the quality of tissue-engineered cartilage. Although the integrin β1–ERK1/2 signal cascade has been implicated in periodic mechanical stress-
