Gelatinolytic activity in cardiac myxomas evaluated by in situ zymography. Overall gelatinolytic activity is lower in nonembolic myxoma tissue (A) than in embolic tumor (B), as demonstrated by increased fluorescence of the quenched fluorescein isothiocyanate-labeled substrate. C: Negative control of embolic myxoma tissue in the presence of 20 mmol/L EDTA. D: A detail of embolic myxoma tissue showing the green positive staining of cells and interstitium. Original magnifications: ×100 (A–C); ×600 (D).
