The present invention describes novel plant derived elastin-like peptides and peptidomimetics that may serve as functional ligands for elastin receptors and stimulate elastogenesis. The novel plant derived peptides provide an alternative (non-animal derived) source of GXXPG (SEQ ID NO. 2) containing peptides. The present invention also describes therapeutic compositions containing novel plant derived peptides or peptidomimetics useful in stimulating elastogenensis and capillary dilatation. The therapeutic compositions of the present invention that comprise novel plant derived peptides or peptidomimetics may be combined with other therapeutic agents.

Dermal fibroblasts permanently loose their ability to synthesize elastin, the major component of elastic fibers, shortly after puberty. This progressive loss of elastic fibers cannot be replaced, resulting in the physical signs of aging. The present invention provides methods and compositions containing the polyphenols ellagic acid and/or tannic acid for protection against degradation of cutaneous elastic fibers by the elastolytic enzymes. The use of ellagic acid and/or tannic acid increased the overall deposition of elastic fibers in healthy and damaged skin cells. The protection of both intra-tropoelastin and extra-cellular mature elastic fibers from proteolytic enzymes by ellagic acid and tannic acid caused an increase in the net deposition of elastic fibers. Therefore, embodiments of the present invention provide methods and composition for the treatment of skin and prevention and treatment of degradation of dermal elastic fibers.

Embodiments provide methods for using ascorbate for the stimulation of production of elastic fibers by cells.

Sodium ascorbate stimulation of elastogenesis

Compositions and methods for inducing the deposition of elastin in skin by administering compositions including a mineralocorticoid, such as, for example, aldosterone and, optionally, a secondary active agent for enhancing or modulating the effect of the mineralocorticoid are described herein.

Composition for elastin production

Compositions and methods for inducing the deposition of elastin by administering compositions including a mineralocorticoid, such as, for example, aldosterone and, optionally, a secondary active agent for enhancing or modulating the effect of the mineralocorticoid are described herein.

Aldosterone induced vascular elastin production

The present invention describes therapeutic compositions comprising one or more minerals, including trivalent iron, divalent manganese and salts thereof, suitable in facilitating synthesis and deposition of connective tissue matrix, particularly rich of elastin and collagen, and mitogenic potential in human dermal fibroblasts. It also describes the phenomenon in which stimulation of elastogenesis by arterial SMC associates with a net decrease in proliferation of these cell types. The present invention also describes methods of treatment of human skin fibroblasts and arterial smooth muscle cells. The therapeutic compositions of the present invention comprise one or more of trivalent iron or divalent manganese or salts thereof and may be combined with an elastic tissue digest.

Compositions for elastogenesis and connective tissue treatment

The present invention describes therapeutic compositions comprising fibroblasts that have been stimulated to increase expression of extracellular matrix components or elastin, or to produce enhanced elastogenesis or the appearance thereof at a site of administration. The therapeutic fibroblast formulations can be prepared using a variety of elastogenic agents, including digests of mammalian elastin, chemically digested plant extracts comprising elastin-like peptides, and synthetic elastogenic peptides. The invention further comprises cosmetic and pharmaceutical treatment methods using the therapeutic fibroblast compositions of the invention.
