Abstract

Scaffold materials suitable for the scale-up and subsequent commercialization of tissue engineered products should ideally be cost effective and accessible. For the in vitro culture of certain adherent cells, synthetic fabrication techniques are often employed to produce micro- or nano-patterned substrates to influence cell attachment, morphology, and alignment via the mechanism of contact guidance. Here we present a natural scaffold, in the form of decellularized amenity grass, which retains its natural striated topography and supports the attachment, proliferation, alignment and differentiation of murine C2C12 myoblasts, without the need for additional functionalization. This presents an inexpensive, sustainable scaffold material and structure for tissue engineering applications capable of influencing cell alignment, a desired property for the culture of skeletal muscle and other anisotropic tissues.
