Evaluation of isolated passage 1 and passage 5 synovial cells from moderate-grade synovitis in osteoarthritis. a Outgrowth of synovial cells from synovial non-digested fragments (Passage 0). Passage 1 synovial cells characterized by a mix of cells with a spindle and a polygonal-star shape. Passage 5 synovial cells characterized only by spindle-shaped morphology. b CD3,CD14, CD16, CD31, CD34, CD45, CD55, CD68, CD73, CD80, CD90, CD105, CD106, and CD163 immunocytochemical staining on passage 1 and passage 5 synovial cells analyzed by flow cytometry. Data are expressed as the median and interquartile range (nā€‰=ā€‰22). *Significant differences between passage 1 and passage 5 synovial cells: pā€‰<ā€‰0.005. ND not detected
