Native and artificial extracellular matrices (ECMs) have been widely applied in biomedical fields as one of the most effective components in tissue regeneration. In particular, ECM-based drugs are expected to be applied to treat diseases in organs relevant to urology, because tissue regeneration is particularly important for preventing the recurrence of these diseases. Native ECMs provide a complex in vivo architecture and native physical and mechanical properties that support high biocompatibility. However, the applications of native ECMs are limited due to their tissue-specificity and chemical complexity. Artificial ECMs have been fabricated in an attempt to create a broadly applicable scaffold by using controllable components and a uniform formulation. On the other hands, artificial ECMs fail to mimic the properties of a native ECM; consequently, their applications in tissues are also limited. For that reason, the design of a versatile, hybrid ECM that can be universally applied to various tissues is an emerging area of interest in the biomedical field.

Objective: To determine the inhibition activity of Typhonium flagelliforme Lodd. Blume (T. flagelliforme) leaf extract on cyclooxygenase 2 (COX-2) expression of colon cancer cells. Methods: T. flagelliforme leaf extract was prepared to macerate in ethyl acetate. In vitro anticancer activity was assayed by MTT method on WiDr colon cancer cells. This study applied apoptosis induction assay to investigate the mechanism of cell death using double staining method. COX-2 expression was stained by immunocytochemistry. Results: T. flagelliforme showed anticancer activity and induced apoptosis on WiDr cells through inhibition of COX-2 expression with IC
