Synovial levels of mRNA from procoagulant and fibrinolytic genes in AIA, as analyzed by RPA. (a) Autoradiographic signals of synovial RNA samples from left (L; control) and right (R) knees, 4 h after arthritis induction. The single sample shown for each condition shows the typical, reproducible pattern obtained from the RPA analysis of at least three different RNAs, each from different animals. (b) Same as (a), but 7 d after arthritis induction.
