Abstract
Menisci are a pair of crescent-shaped fibrocartilages and composed primarily of type I collagen. Inner region of the meniscus has similar characteristics to articular cartilage. Low-intensity pulsed ultrasound (LIPUS) has been reported to have chondroprotective effects on chondrocytes by inducing the expression of chondrocyte differentiation markers and CCN2/CTGF production. Here, we describe an experimental approach that investigates the distinct cellular behavior of human inner and outer meniscus cells in response to LIPUS stimulation. Our experimental model can analyze the relationships between LIPUS-induced CCN2 and its repairing role in the meniscus.
