Comments
The cells undergo a pre-adipose to adipose like conversion as they progress from a rapidly dividing to a confluent and contact inhibited state. A high serum content in the medium enhances fat accumulation [PubMed ID: 4426090].
Tested and found negative for ectromelia virus (mousepox).
This line is also designated as ATCC CCL-92.1. ATCC CL-173 was deposited in 1974 without passage number information from the depositor. 
Complete Growth Medium The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: bovine calf serum to a final concentration of 10%.
Subculturing
Protocol: Never allow culture to become completely confluent.
  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin - 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
  3. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
    Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37C to facilitate dispersal.
  4. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
    The recommended inoculum is 2 to 3 X 103 cells/cm2. Subculture before cultures become 70 to 80% confluent or when cells reach 5 to 6 X10(4) viable cells/cm2. Corning® T-75 flasks (catalog #431464) are recommended for subculturing this product.
  6. Incubate cultures at 37°C.
Interval: Every three days
Medium Renewal: 2 to 3 times per week
Cryopreservation
Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase
Culture Conditions
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37°C
Growth Conditions: The serum used is important in culturing this line. Calf serum is recommended and not fetal bovine serum. The calf serum initially employed and found to be satisfactory was from the Colorado Serum Co. Denver.
Name of Depositor Massachusetts Institute of Technology
Passage History
ATCC CL-173 was deposited in 1974 without passage number information from the depositor. At the time of submission, ATCC prepared approximately 30 vials of seed stock at about 4 passages beyond the original depositor material (passage number: unknown +4).
