Fibrin(ogen) accumulates in the peritoneal wall of plasminogen-deficient mice after peritoneal thioglycollate injection. Immunofluorescence staining of the peritoneal wall of Plg^+/+ mice (A), Plg^−/− littermates (B), and Fib^−/− mice (C) for fibrin(ogen) 72 hours after peritoneal thioglycollate injection (40×). (D) Mean AI555 intensity representing fibrin accumulation was quantified in 5 fields per mouse. Data are shown as individual values with means indicated. DAPI, 4′,6-diamidino-2-phenylindole.
