A drug screening platform simulating hyperthermic intraperitoneal chemotherapy including a dielectrophoresis system, a microfluidic chip and a heating system is disclosed. The dielectrophoresis system is used to provide a dielectrophoresis force. The microfluidic chip includes a cell culture array and observation module and a drug mixing module. The cell culture array and observation module are used to arrange the cells into a three-dimensional structure through the dielectrophoresis force to construct a three-dimensional tumor microenvironment. The drug mixing module is coupled to the cell culture array and observation module and used to automatically split and mix the inputted drugs and output the drug combinations into the cell culture array and observation module. The heating system is used for real-time temperature sensing and heating control of the drug combinations on the microfluidic chip to simulate high-temperature drug environment when performing hyperthermic intraperitoneal chemotherapy on the three-dimensional tumor microenvironment.

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.

A device to aid in the production and regeneration of tissues and organs, standing alone, or on or inside of the human body, with a method of fabrication of tissues and organs and use of the device.

An apparatus for culturing cells includes a bioreactor. The bioreactor may be modular and may include in a chamber a fixed bed, such as an unstructured or structured fixed bed (such as a spiral bed) for culturing cells, with a return column arranged centrally within the chamber. The modular bioreactor may include a plurality of structured fixed bed arranged in a stacked configuration. The modular bioreactor may include an outer casing forming a space for conditioning (e.g., insulating, heating, cooling) at least a chamber in which cells are cultured. The bioreactor may also include an impeller with radially curved blades, and may also suspend the impeller so that it may move from side-to-side and align with an external drive. Related methods are also disclosed.

A bioreactor chamber (1) including a first end block (4), a second end block (6) and a flexible membrane (2). The flexible membrane (2) extends between the first end block (4) and the second end block (6) and defines a cavity (10) bounded by at least the flexible membrane (2). The cavity (10) is arranged to receive a substrate, for growing a culture on the substrate or a biomaterial for testing the biomaterial.
