Abstract

A method for treating an oral condition of a subject by grafting cultured tissue constructs to the oral tissue. The cultured tissue constructs comprise cultured cells and endogenously produced extracellular matrix components without the requirement of exogenous matrix components or network support or scaffold members. Some tissue constructs of the invention are comprised of multiple cell layers or more than one cell type. The tissue constructs of the invention have morphological features and functions similar to tissues their cells are derived and their strength makes them easily handleable. Preferred cultured tissue constructs of the invention comprise cells derived from human tissue.

Claims (1)

1. A method for treating recessed oral gingiva in a subject, said method comprising: grafting a contracted cultured tissue construct to an oral tissue of the subject, wherein said contracted cultured tissue construct comprises a gel mixture of a collagen solution and a contractile agent, wherein the contractile agent comprises cultured dermal fibroblast cells derived from human neonate male foreskin, wherein the contracted cultured tissue construct does not comprise oral mucosal cells or autologous cells, and wherein the treatment of the recessed oral gingiva with the contracted cultured tissue construct in said subject results in a functional zone of attached gingiva that is comparable to the functional zone produced from grafting a free autogenous graft to an oral tissue.
