After subculturing of cancer cells, I place the Petri plate and t-flask into co2 incubator. cells are attached normally but after 24-72 hrs, cells became disappearing. Even under the microscope examination also we could not find any cells and also cells debris. The medium looks a very clear one... Pls, help me with this problem.
and if I placing any one of a flask into neighbors incubator, cells are grown healthy and normal.
