Abstract: Methods of generating an innervated muscle structures are disclosed as well as bioengineered structures for tissue repair or regeneration. The methods can include the steps of obtaining populations of smooth muscle cells and neuronal progenitor cells and then seeding the cells together onto a matrix material, followed by culturing the seeded cells to form an innervated smooth muscle cell construct of directionally oriented smooth muscle cells. In one embodiment, the neuronal progenitor cells can be seeded first as neurospheres in a biocompatible solution, e.g., a collagen/laminin solution, and allowed to gel. Next, a second suspension of smooth muscle cells can be deposited as separate layer. Multiple layer structures of alternating muscle or neuron composition can also be formed in this manner. Differentiation of the neuronal progenitor cells can be induced by exposure to a differentiation medium, such as Neurobasal A medium and/or exposure to a differentiating agent, such as B-27 supplement.

When tethered to the polymers, the peptide region allows the polymers to bind to HA. The biocompatible polymers are modified to contain a crosslinking group so that the HA can be incorporated into a scaffold and retained in place. The novel biomaterial 1 compositions can be made into hydrogel compositions and used in a variety of tissue applications, using mild crosslinking conditions and they also have the ability to be degraded with hyaluronidase if needed. Furthermore, the novel biomaterial compositions will enable enhanced interaction between the scaffold and encapsulated cells for a wide variety of tissue engineering applications. Methods of making hydrogel compositions and their use are also provided.
