System for growing tissue cultures

A culture plate for growing tissue in vitro comprising:

• a base plate;
• at least one culture container affixed to the base plate, said culture container having an upstanding wall emanating from the base plate;
• an opening in one end of said container through which a tissue sample may be introduced;
• a removable cover for closing said opening to seal said one end;
• a wall closing the other end of the container for carrying a culture support,
• and an aperture provided in the said wall closing the other end of the container for the entry of nutrients and oxygen to the container interior.

An assembly for growing tissue comprising:

• a flat plate approximately the size of a standard microscope slide;
• at least one cylindrical container formed as an integral part of the plate on one surface thereof, with an opening through the plate providing access to the container through one end thereof;
• a removable end wall closing one end of the container and a fixed wall particularly closing the other end of the container;
• an aperture in the fixed wall through which a nutrient solution may pass to the interior of the container;
• a cellulose support having a well therein and adapted to be mounted in the container with the well aligned with the aperture;
• a permeable membrane attached to the support and closing one end of the well, said membrane lying across the aperture when the support is disposed in the container, said membrane being capable of carrying a tissue sample on its surface facing the well;
• and a ballast member attached to the plate for submerging the plate with its container in a nutrient bath.
