What would happen if the cells from one part of a developing embryo were transplanted to another part of the embryo after differentiation?

If cells from one part of a developing embryo are transplanted to another region after differentiation, they may not integrate properly due to their specialized functions and the cues from their original environment. This can lead to improper tissue formation, dysfunction, or rejection by surrounding cells. The transplanted cells could struggle to adapt to their new location, potentially disrupting the overall development and homeostasis of the embryo. In some cases, this could lead to developmental anomalies or malformations.
