Abstract: The invention is directed to methods of inducing cell recruitment and tissue regeneration at a target site in a subject. It is also based, in part, on the discovery that a subject's own biologic resources and environmental conditions can be used for in situ tissue regeneration and thereby reduce or eliminate the need for donor cell procurement and ex vivo manipulation of such donor cells. Methods are disclosed for recruitment of a subject's own stem cells to a target region by inducing a sustained positive pressure at a target site, such as the kidney, thereby increasing the number of pluripotent cells capable of differentiating to regenerate the target tissue.

Abstract: A plant fat-based scaffold for growing cell-based meat products for consumption. The scaffold comprises primarily plant fats or waxes in addition to cell binding proteins and optional additional components that assist in the growth of cultivated animal cells. The scaffold can exist in both a liquified state during sterilization and a solid state during the formation of the scaffold, the seeding of the cultivated cells, and the cellular growth phase. The scaffold is capable of remaining in the final product for consumption or is partially or completely melted out of the final product and recycled into raw material for forming new scaffolds.
