Dear all, I am culturing the embryonic stem cells of zebrafish. My cells start to attach and form big colonies although I swirl the plate after seeding. Now, I worry that the colonies might be cancer cells, but I don't know how to distinguish them between normal colonies and cancer cells. Besides, what is the differences between embryoid body and normal forming colonies? Can embryoid body formed spontaneously?

p/s: I am using liquid medium with LIF free, the well is coated with 0.1% gelatin, and feeder free.

Thank you!

needs some infor about howu subculting these cells

from r note, it is clear that the ES cells since grown at high density spotaneously forms 3d structures -EBs which a way to say that they undergoing differentiation.

Hi enock

I don't know much about zebra fish stem cell markers, but you could just stain them to be sure that you have the right cells (a picture would also be nice).
In the meantime check these papers out:

If you can't get them PM me.

Best regards
