Pool platelet-rich plasma lysate therapy increases
synoviocyte proliferation and hyaluronic acid production while protecting chondrocytes from synoviocytederived inflammatory mediators.
mTOR Senses Environmental Cues to Shape the Fibroblast-like
Synoviocyte Response to Inflammation.
Moreover, there is considerable variability between biopsies from a single joint, resulting from variations in lining thickness (Smith et al., 2003), sublining composition, and an unequal distribution of
synoviocyte types in the synovial membrane (Shikichi et al., 1999; Iwanaga et al., 2000).

synoviocyte MH7A," Clinical & Developmental Immunology, vol.
Recent evidence suggests that human articular chondrocyte can actively produce ROS which are released during inflammation of the synovial membrane of
synoviocyte. These ROS with oxidative activity play a key role in the chondrocyte catabolic program, being the mediators and effecters of cartilage damage.
Human MH7A synovial cell is an immortalized cell line by stably transfecting rheumatoid fibroblast-like
synoviocyte cells with SV40 T antigen gene.

ROS are released during inflammation of the Synovial membrane of
synoviocyte. These radical oxygen species with oxidative activity play an important role in the Chondrocyte catabolic program: being the mediators and effecters of cartilage damage.
It is involved in induction of the inflammatory cascade as well as processes destructive to joints, including osteoclast activation and
synoviocyte proliferation.

At 4 and 8 weeks of age, in TARV-inoculated birds, the gastrocnemius tendon sheath showed prominent lymphocytic infiltration in the subsynovium along with mild
synoviocyte hyperplasia.
