How do the plant cells placed in a medium for tissue culture change terms of their degree of specialization?

The plant cells first placed in a medium for tissue culture are differentiated cells. The cells produce undifferentiated cells that are pluripotent, or able to develop into all the specialized cell types and structures of the plant. The embryonic stem cells of an animal are the most similar to the plant cells that first develop in a tissue culture because they can develop into all the different cell types and structures of a specific animal.
