Abstract: The present invention relates to methods for preparing bio scaffolds useful in the repair of tears. More specifically, the invention relates to a method of treating rotator cuff tear in a mammalian subject in need thereof comprising the steps of: (i) selectively expanding tenocytes in vitro in culture medium comprising insulin or a functional derivative and a glucocorticoid or a glucocorticoid-like molecule to produce a culture of expanded tenocytes; (ii) seeding a bioscaffold with said expanded tenocytes to produce a tenocyte seeded bioscaffold; and (iii) implanting said tenocyte seeded bioscaffold proximal to the rotator cuff tear. The present invention also relates to a bioscaffold comprising cells, wherein more than 80% of said cells are tenocytes.
Abstract: The present invention relates to methods of repairing tissue. More specifically, the present invention relates to methods of using cells and an implantable support for the repair of tissue defects, where the implantable support and cells are implanted into the tissue defect less than 2 hours after the cells are applied to the support.
