Administration of a Suspension of Autologous Fibroblasts to Promote Tissue Regeneration and Correct Defects in Tissues
Method of Obtaining an Injectable Cell Pharmaceutical Composition
[0074] As disclosed above, one embodiment of the present invention comprises a method for regenerating tissue that has been damaged in a subject as a result of a disease or disorder in the subject, wherein the method comprises providing a pharmaceutical composition comprising of autologous, passaged fibroblasts substantially free of immunogenic proteins (e.g., culture medium serum-derived proteins), identifying a site of tissue degeneration or a defect in tissue, injecting an effective amount of the pharmaceutical composition into the tissue at the site of the tissue degeneration or defect so that the tissue is augmented, and the growth of tissue is promoted at the site of degenerated tissue.
[0075] A disease or disorder which promotes tissue degeneration in a subject, and can be treated with this asp...

A Composition for Promoting the Regeneration of Tissue that Has Degenerated in a Subject
[0092] Also disclosed in the present invention is a composition for promoting the regeneration of tissue that degenerated in a subject. Such degeneration can occur as a result of periodontal disease, trauma, dermatoses, recurrent aphthous stomatitis, or infections to name only a few. Other relevant diseases and disorders are listed above. Moreover, examples of periodontal disease which can cause tissue degeneration include periodontal degeneration, gingivitis, or non-healing wounds of the palatal mucosa or gingival mucosa. Moreover, a composition of the present invention can also be used to correct defects in tissue of a subject, such as, for example, defects in the palatal mucosa, gingival mucosa, or defects in skin, e.g., any of those described above. Such compositions can be used, for example, for healing extraction sockets after extraction of a tooth. Moreover, they can be used to fill extra...

An Injectable Composition for Correcting Skin Defects and Augmenting Tissue in a Subject
[0112] As explained above, the present invention extends to an injectable composition for correcting a defect in skin of a subject, or augmenting tissue of a subject, wherein the injectable composition comprises passaged autologous fibroblasts substantially free of immunogenic proteins (e.g., culture medium serum-derived proteins), and a biodegradable, acellular injectable filler material. Examples of skin defects that can be treated with the present invention include scars, particularly facial scars resulting from trauma or acne, or wrinkles. Any of the other skin and other tissue defects listed above can also be treated with the present invention. Furthermore, the present invention can be used to augment tissue in a subject. For example, the injectable composition of the present invention can be injected into the lips of a subject in order to make the lips larger and fuller, or it can be injec...
