1. A method of generating a scaffold comprising:
(a) homogenizing decellularized extracellular matrix (ECM) in an organic solvent using a bead homogenizer to generate a homogenate of decellularized ECM;
(b) contacting said homogenate of decellularized ECM with a synthetic polymer so as to increase viscoelasticity of said homogenate of decellularized ECM, wherein an amount of said synthetic polymer in said homogenate of decellularized ECM is between 0.05-1% mass of said homogenate of decellularized ECM; and subsequently
(c) electrospinning said homogenate of decellularized ECM onto a solid surface thereby generating the scaffold composed of ECM fibers; and subsequently
(d) removing said polymer following said electrospinning such that the scaffold is devoid of said synthetic polymer, wherein the method is performed in-vitro.
