Non-specific cell–scaffold interface

The non-specific cell–scaffold interface represents the physical and chemical boundary where living cells interact with synthetic or natural biomaterial scaffolds (Stevens & George, 2005). This interface is not a discrete molecular target such as a receptor or enzyme, but rather a dynamic environment that dictates cellular responses through surface properties such as topography, energy, and chemistry (Hubbell, 1995). These physical properties govern the non-specific adsorption of extracellular matrix proteins from the surrounding medium, which then facilitate cell adhesion and signaling through mechanotransduction pathways (Vogel & Sheetz, 2006). In regenerative medicine, the design of this interface is critical for guiding tissue formation and preventing the foreign body response, which can lead to fibrous encapsulation and implant failure (Anderson et al., 2008). While traditional pharmacological agents do not typically target this interface, biomaterial design specifically modulates its properties to improve the integration of medical devices and the efficacy of cell-based therapies.
