    摘要: A multi-layered tissue construct includes: a first layer comprising a first hydrogel; and a second layer comprising a second hydrogel, wherein the first layer is connected to the second layer at a first transition zone and wherein at least one of the first layer and the second layer further comprises a component selected from the group consisting of cells and a bioactive substance. Another multi-layered tissue construct includes: a first layer comprising a first hydrogel; a second layer comprising cells of a first type, wherein the second layer is disposed on the first layer; and a third layer comprising a second hydrogel and optionally cells of the first type encapsulated in the second hydrogel, wherein the third layer is disposed on the second layer. Methods for producing these multi-layered tissue constructs are also disclosed.

    摘要: The present invention relates to the covalent binding of a hydrogel to an extracellular matrix (ECM). The integration of the hydrogel with the tissue is superior to that in previous techniques. Moreover, unlike previous techniques, the present invention does not require a photoinitiator. Potential therapeutic applications include tissue repair and delivery of drugs or cells. The ECM is first exposed, then treated with a priming agent. Then a polymerizable agent is added and crosslinked to the ECM. Two primary embodiments of methods are disclosed. In the first, the priming agent is an oxidizer which creates tyrosyl radicals in the ECM, which are then bound by acrylate groups in the polymerizable agent. In the second, the priming agent contains aldehydes which bind amino groups in the ECM.
