ABSTRACT:
A disclosure is made of various apparatus and methods for culturing and preserving cells and tissue in ways that minimize contamination potential, direct cells to reside in desired areas, allow uniform cell distribution during seeding, provide optimal growth conditions by controlling the amount of medium residing in proximity of cells, allow desired compounds and molecules to reside in proximity of the cells, allow co-culture, provide for efficient scale up, allow a desired shape of tissue to be created while retaining a closed system, and allow cryopreservation and reconstitution of cell and tissue while retaining a closed system. The apparatus and methods can be combined to prevent the need to remove the tissue from the enclosure at any point during the sterilization, seeding, culturing, cryopreservation, shipping, or restoration process. Also disclosed is an apparatus and method of pipette interface with a container in a manner that blocks contaminants from entering the container.
