Reactive synovial lining cells
WebMay 11, 2024 · The synovial intimal lining has long been considered a loose association of cells serving as an ineffective barrier owing to a lack of classical adhesion structures such as tight junctions ... WebThe synovial lining layer was scored for the number of CD68+ cells, the mean lining layer thickness, and the maximal lining layer thickness. Mean and maximal lining thickness were scored separately as it appeared that synovial lining layer hyperplasia can be focal and thus that both variables can be discrepant in some samples.
