Abstract: Aspects of the disclosure relate to bioreactors for maintaining biological objects (e.g., organ or engineered tissues) under culture conditions. In some embodiments, bioreactors and cover assemblies are provided that comprise a support base for supporting a biological object. In some embodiments, bioreactors and cover assemblies are provided that comprise a movable support base configured such that a user can manipulate its position and thus the relative position of the biological object.

Abstract: Aspects of the disclosure relate to rotating bioreactors and articles and methods that are useful for adapting a rotating bioreactor for use with tissues or scaffolds of different sizes. In some embodiments, bioreactors comprising a reservoir and an arbor assembly are provided herein, in which the arbor assembly comprises a rotatable support to which a tissue or tissue scaffold can be attached.

Abstract: Aspects of the invention relate to a combination of techniques and/or materials that can be used to form a synthetic scaffold for solid and/or hollow organs or tissue. In some embodiments, methods are provided that involve assembling a synthetic scaffold using a first material for a first structural component and a second material for a second structural component, in which the first or second structural component is a perfusion pathway. In some embodiments, materials (e.g., synthetic materials) for the scaffold are printed, molded, cast, polymerized, or electrospun. In some embodiments, a scaffold may mimic a natural scaffold or several features of a natural scaffold.

Abstract: Aspects of the disclosure provide techniques for detecting differences and/or changes in biological and non-biological material using infrared imaging. Aspects of the disclosure are useful for monitoring and evaluating synthetic scaffolds and engineered tissue and organs for tissue engineering and transplantation.

Abstract: A synthetic scaffold for replacing at least a portion of an airway includes an airway mold, one or more structural ribs on the airway mold, and a non-structural wall. Each of the one or more structural ribs is formed from a first material and the non-structural wall is formed from a second material. The non-structural wall coats the airway mold and forms a conduit that incorporates the one or more structural ribs.
