I am looking at the Axol's IPSC-derived sensory neuron progenitors user guide. It stated that the cells after plated need to be treated mitomycin C to stop flat-non neuron cells proliferation. May I know why there are non-neuron cells? And the user guide also advises against the expansion of the cell lines due to the necessity of mitomycin C treatment. This seems not feasible to adopt the cell lines in my research project due to budget constraint. Has anyone try to expand this cell line before? Kindly advice. Thank you
