1. cells on scaffolds or primary tissue explants establish a uniform very low shear fluid suspension orbit within the horizontally rotating culture vessels As the cells proliferate the rotation speed is adjusted to compensate for increased sedimentation rates The absence of damaging stress forces allows three dimension aggregation of large cell masses Normal neoplastic mono and co cultures of fragile human anchorage dependent and suspension cells have been grown in vitro One of the primary advantages of the new Rotary Cell Culture System over conventional systems is its ability to grow tissue cultures that differentiate or mimic the structure and function of the parent tissue The investigator can inoculate the culture with the same mixture of cells which normally occurs in vivo These cells grow and organize into three dimensional tissue aggregates similar to the parent tissue Such growth is possible because destructive turbulence and collision forces are minimal within the horizontal Rotary Cell Culture System Surgical explants or biopsies can be transferred into the RCCS and be maintained without necrosis This extremely low shear culture environment can be used to grow virtually any cell type that can be cultured in conventional culture systems see the bibliography at www synthecon com for examples The SYNTHECON Inc Rotary Cell Culture System RCCS enables a scientist with a standard tissue culture laboratory to produce very com2. equivalent overnight 7 Air dry the vessel parts 8 Assemble vessel 9 Sterilize as described below Sterilization Autoclave Method 1 Remove fill port cap and autoclave separately from vessel 2 Place plastic caps or aluminum foil on syringe ports to protect from contamination during reassembly 3 Loosen center bolt 1 turn with Allen wrench tool supplied 4 Place vessel and cap in autoclave bag or wrap with foil and autoclave for 20 minutes at 121 C 5 Remove from autoclave and allow to cool Experimental Start up 1 Transfer the vessel to a laminar flow hood Place the fill port plug on a sterile alcohol swab 2 Attach sterile valves to the syringe ports 3 Fill the vessel partially with media leaving enough space to add cells and scaffolds or microcarriers 4 Add scaffolds or microcarriers via the fill port 5 Add cells If desired cells and microcarriers can be mixed and added together 6 Fill the remaining volume of the vessel with media and insert the fill port plug There will always be small bubble remaining after this step It is necessary to remove this bubble before starting the culture in order to minimize turbulence 7 Bubble removal Fill a 3 or 5 ml sterile syringe with media and attach to one of the valves on a syringe port Attach a 3 or 5 ml sterile syringe on the valve of the other port Open both valves Maneuver the bubble under the empty syringe port and inject media from the filled syringe R
3. 55 ml only C Syringe Ports D Front Plate E Back Plate With a few exceptions noted below the procedures for the High Aspect Ratio Vessel are the same as with the Slow Turning Lateral Vessel 1 The smaller vessels do not have a fill port Consequently filling of these vessels must be done through the syringe ports This also limits the size of the scaffolds to those that can be introduced through the syringe ports 2 The High Aspect Ratio Vessel is held together with small screws around the periphery of the Front plate Each of these screws should be loosened during autoclaving and then tightened before adding media Do not overtighten these screws 10 2 When changing media the vessel should be placed vertically in the hood with the fill port at the top and secured to prevent it from rolling The cell aggregates or scaffolds are allowed to settle at the opposite end of the vessel from the fill port The vessel should then be propped at a shallow angle to keep the aggregates or scaffolds at one end and the fill port opened A pasteur pipet connected to a vacuum source is then introduced through the open fill port and as much media as possible removed without disturbing the concentrated aggregates or scaffolds at the other end of the vessel Fresh media is then added the fill port plug replaced and the bubbles removed as described with the Slow Turing Lateral Vessel Equipment Usage Rights SYNTHECON Inc grants the purch

9. in the RCCS Developed at the Johnson Space Center the system was originally designed to protect delicate tissue cultures during spaceflight However it quickly became apparent that the unique environment of low shear force high mass transfer and simulated microgravity provided by the system enables 3D cell growth to take place in a conventional laboratory tissue culture incubator Two basic types of RCCS vessels are manufactured by SYNTHECON Inc The Slow Turning Lateral Vessel STLV is tubular shaped and has a central gas transfer core and is designed for use primarily with anchorage dependent cells The High Aspect Ratio Vessel HARV has a disc shaped culture chamber with the oxygenator membrane forming the inside wall of the vessel The HARV was designed for use with suspension cells However experience has shown it to be an excellent culture vessel for anchorage dependent cells and tissue explants as well Principles of Operation Tissue Culture in the Rotating Cell Culture Vessel The Rotary Cell Culture System is a horizontally rotated bubble free culture vessel with membrane diffusion gas exchange The culture medium cells and cell aggregate particles rotate with the vessel and do not collide with the vessel walls or any other damaging objects when rotated at appropriate speed Destructive shear forces are minimized because this system has no impellers airlifts bubbles or agitators Suspension cells anchorage dependent
