Detection of mRNA (a) and the number of cells immunoreactive for different components of the prostanoid system (PGE2, mPGES, COX-2, and EP1-4) (b) in patients with osteoarthritis (OA). (a) Quantification of mRNA specific for COX2, EP1-4, and mPGEs-1 in synovium of OA patients. (b) Quantitative analysis of COX2-, EP1-4-, and mPGEs-1-IR cells in OA synovium. Data are shown as . (c) Confocal microscopy of EP3 (red fluorescence; a, b) and mPGES or COX2 (green fluorescence; c, d) double immunofluorescence (e–h) in OA synovium. . DAPI blue fluorescence shows nuclear staining. .
