Hi

I am growing stem cells. But after a while i have a mixed culture of both differentiated and undifferentiated population. could you kindly tell me as to how can i get rid of the differentiated cells. i need only undifferentiated stem cells for my work

thanx for help

Could you give a little more information about what cells you are growing? ES cells? Mouse or Human or..?

i am growing mouse ES cells and they are without MEFs. the number of ES colonies are getting lesser as the cells are getting differentiated though the medium has LIF. all your suggestions would be very helpful..

Is it possible to thaw a new batch of cells? Probably not the answer you want.

IS this a standard line used in many labs, or a novel/less well caracterized line?
