Recovery from growth inhibition in irradiated MO4 spheroids: suspension cultures versus explanted cultures.
Spheroids of MO4 mouse fibrosarcoma cells were irradiated with single doses of photons between 1 and 50 Gy. Growth of irradiated spheroids was followed in suspension culture and after explantation on glass. We found that MO4 spheroids recovered from higher doses of irradiation when they were explanted on glass than when they were kept in suspension culture. These results suggest that irradiated MO4 cell populations may become anchorage-dependent for growth.
