Elastogenic Effects of Hyaluronan Oligosaccharides and Their Applications in Tissue Engineering (includes 07-054)

Market Overview:

Elastin is a critical component in all connective tissue and is not readily regenerated by the body. In order to develop or regenerate functional connective tissue, elastogenic cues to synthesize, organize, and stabilize the extracellular matrix are critical.

The invention includes novel elastogenic cues for injured or developing connective tissues (i.e. cardiovascular, dermal, pulmonary, and other elastin containing tissue) that will encourage the development of functional and structurally sound tissues. These cues include hyaluronan fragments and oligomers, optionally in conjunction with growth factors and/or a source of copper ions.  There are numerous attractive potential applications including vascular disease treatment, cosmetic skin rejuvenation, tissue engineering advancement and more.  Additionally the flexibility of options for delivering the elastogentic agents to the tissue, together with the physiological benefits of the agents themselves, provide a compelling basis for many product development opportunities.

In vascular tissue, elastin is an important component of blood vessels associated with retraction of the blood vessel following dilation from blood flow. Stabilization and regeneration of elastin could result in effective treatment of aneurysm.  An additional feature of this technology is the usage of hyaluronan oligosaccharides to suppress smooth muscle cell growth and proliferation which are associated with vascular occlusion in atherosclerosis and restenosis.
