Abstract:
Decellularized plant tissues and the use of these plant tissues as scaffolds are disclosed herein. Particularly, decellularized plant tissues are functionalized such to allow for human cell adhesion, thereby allowing for their use as scaffolds for human cells. These scaffolds can then be used in a number of applications/markets, including as research tools for tissue engineering, regenerative medicine, and basic cellular biology.
Abstract:
The invention provides a scaffold of extracellular matrix polymers with recombinant chimeric peptides tethered thereto, The invention also provides recombinant chimeric peptides of antimicrobial peptides and extracellular matrix binding domains. The invention also provides methods for treating chronic wounds using the scaffold and/or recombinant chimeric peptides.
Abstract:
Methods and systems for increasing oxygen for use by mammalian cells are provided. In some embodiments, a method for increasing oxygen concentration for mammalian cells coculturing chloroplasts in at least one well plate with mammalian cells in a media and increasing oxygen production by exposing the chloroplasts to light.
Abstract:
An engineered muscle construct in the form of a braided collagen microthread scaffold is provided. The microthread scaffold can be used with or without cells as engineered skeletal muscle. The microthread scaffold can also be used to promote cell attachment and growth to deliver cells to a large muscle defect to stimulate muscle regeneration. Methods for making a muscle construct, seeding cells onto microthread scaffolds and treating muscle defects are also provided.
Abstract:
De-differentiation protocols are described herein for generating progenitor cells from adult connective tissue, in particular adult human fibroblasts. The de- differentiation protocols described herein comprise culturing the differentiated cells with an amount of FGF2 to de-differentiate the cells. These de-differentiated cells may then be cultured and used for experimentation, amplification and clinical applications. The clinical applications include the use of the cells for tissue and cell based therapies.
