Yes / Cell behavior in terms of adhesion, orientation and guidance, on extracellular matrix (ECM)
molecules including collagen, fibronectin and laminin can be examined using micro contact
printing (MCP). These cell adhesion proteins can direct cellular adhesion, migration,
differentiation and network formation in-vitro. This study investigates the effect of microcontact
printed ECM protein, namely fibronectin, on alignment and morphology of HeLa cells
cultured in-vitro. Fibronectin was stamped on plain glass cover slips to create patterns of
25μm, 50μm and 100μm width. However, HeLa cells seeded on 50μm induced the best
alignment on fibronectin pattern (7.66° ±1.55SD). As a consequence of this, 50μm wide
fibronectin pattern was used to see how fibronectin induced cell guidance of HeLa cells was
influenced by 100μs and single pulse electric fields (PEF) of 1kV/cm. The results indicates that
cells aligned more under pulse electric field exposure (2.33° ±1.52SD) on fibronectin pattern
substrate. Thus, PEF usage on biological cells would appear to enhance cell surface attachment
and cell guidance. Understanding this further may have applications in enhancing tissue graft
generation and potentially wound repair. / Ministry of Higher Education Malaysia and UTHM Tier 1 Research Grant (U865)
