Abstract

Disclosed herein are contractile cell constructs comprising contractile cells, or progenitors thereof, adhered to a surface of a three dimensional fibroblast containing scaffold (3DFCS) and methods for using them to treat disease. In one aspect, the present invention provides methods for preparing a contractile construct, comprising (a) seeding immature contractile cells onto the surface of a three dimensional fibroblast containing scaffold (3DFCS) to produce a contractile construct; and (b) culturing the contractile construct under conditions to promote differentiation of the immature contractile cells into mature contractile cells, wherein the mature contractile cells form striations. In a further aspect, the invention provides methods for treating a disorder characterized by a lack of functioning contractile cells, comprising contacting a patient with a contractile cell-based disorder with an amount effective to treat the disorder with the construct of any embodiment or combination of embodiments of the invention.
