I did today tissue culture for mcf7 cell line( breast cancer) and i check my work under microscope i saw this below is this cancer cell or just cells debris?
How many days have passed since you passaged these cells? While there are few healthy ones showing up in a different phase contrast, many of your cells are dying or do not look healthy unfortunately. MCF-7 cells do tend to grow slowly at times. Harsh passaging conditions should be avoided. You may try using a milder cell dissociation agent like Accutase instead of Trypsin during passaging.
