Hypothesis

Do cultured cell lines that fail to grow in normal mice become resistant to NK or NC cells after being passaged in a susceptible immunodeficient host?

Conclusion

The hypothesis that cultured cloned murine fibrosarcoma lines become resistant to NK or NC cells after passage in immunodeficient mice is largely unsupported.

Supporting Evidence

  • All tested fibrosarcoma lines were insensitive to NK cells.
  • W319C6 was moderately sensitive to NC cells but became less so after passage.
  • Three of the four cultured lines showed at most slight sensitivity to NC cells.

Takeaway

The study looked at how certain cancer cells react to immune cells in mice, and found that passing these cancer cells through special mice didn't make them better at avoiding the immune system.

Methodology

The study used in vitro assays to assess the sensitivity of murine fibrosarcoma lines to NK and NC cells.

Limitations

The results may vary due to differences in spleen cell donors and assay conditions.

Participant Demographics

Female CBA/Ca mice and CBA backcross nude mice were used.
