What is an example of the effect of environmental factors on cell differentiation?

Environmental factors can alter gene expression, cell signalling and cell differentiation.

Explanation:

Environmental factors can change, stop or disrupt the process of cell signalling and gene expression in organisms. The environmental factors are drugs, chemicals, temperature, etc. With the effect of environmental factors, the organism will try to adapt to the environment by changing the internal process. In case of adaptation, some organism may survive to the changing environment but there is a risk of exhibiting defects and in some case, the result can be death.
