    摘要: Bioscaffoldings formed of hydrogels that are crosslinked in situ in an infarcted region of the heart (myocardium) by a Michael's addition reaction or by a disulfide bond formed by an oxidative process are described. Each of the bioscaffoldings described includes hyaluronan as one of the hydrogel components and the other component is selected from collagen, collagen-laminin, poly-1-lysine, and fibrin. The bioscaffolding may further include an alginate component. The bioscaffoldings may have biofunctional groups such as angiogenic factors and stem cell homing factors bound to the collagen, collagen-laminin, poly-1-lysine, or fibrinogen hydrogel component. In particular, the biofunctional groups may be PR11, PR39, VEGF, bFGF, a polyarginine/DNA plasmid complex, or a DNA/polyethyleneimine (PEI) complex. Additionally, the hydrogel components may be injected into the infarct region along with stem cells and microspheres containing stem cell homing factors. The bioscaffolding may be formed on a stent or a cardiac medical device.

    摘要: A bioscaffolding can be formed from a mixture of gel components of different gelation systems. For example, a bioscaffolding can be formed by mixing at least two different components of at least two different two-component gelation systems to form a first mixture and by mixing at least two different components (other than the components that make up the first mixture) of the at least two different two-component gelation systems to form a second mixture. A treatment agent, such as a cell type or a growth factor, can be added to either the first mixture or the second mixture. In some embodiments, the treatment agent is not added to either mixture. The first mixture can be co-injected with the second mixture to form a bioscaffolding in an infarct region for treatment thereof.
