AbstractDESCRIPTION (provided by applicant): Over 700,000 surgical hernia repairs are performed each year in the United States and despite recent advances, a significant rate of recurrence persists. Of these surgeries, 100,000 are for incisional or visceral herniarepairs, which cost 1.7B annually and have a recurrence rate that can be up to 60%. The incorporation of biocompatible mesh to strengthen the abdominal fascia has largely replaced high-tension suturing techniques in surgical hernia repair. Currently, thepreferred biomaterials include durable synthetic mesh, which bears all the pitfalls of a permanent foreign body; absorbable mesh which does not provide enough long- term support; or bioprosthetics, which are bioabsorbable but still fail at an unacceptablyhigh rate causing recurrent hernias. Surgeons are therefore left to choose between poor options for a repair. Our goal is to accelerate healing rates after hernia repair by using bioprosthetics containing adipose-derived stem cells (ASCs). ASCs were identified in 2001, and have been used for cell therapy in many indications including bone fractures, myocardial repair and soft tissue repair. Their prohealing function is largely mediated through paracrine factors secreted at the site of injury to promote vascularization and tissue remodeling. The product will be a point-of-care ASC seeded bioprosthetic that will promote faster healing times, prevent infection, and leave a biologic repair. Our bioprosthetic is designed to prevent recurrence of incisional hernias, thereby reducing inpatient follow-up care, additional surgeries, and patient distress. PUBLIC HEALTH RELEVANCE: Improving the rate of healing after surgical hernia repair will reduce pain, discomfort and follow-up care. The use of adult stem cells in soft tissue healing represents a potential improvement for surgical procedures. This proposal will develop a novel bioprosthetic for the local retention of cells to improve healing rates and reduce recurrence of incisional hernia repairs.
