Q

(induction/differental growth) A chemical signal will cause a change in cells, resulting in migration, differentiation, or other change.
Chemical can be a surface signaling molecule or some chemical released into the extracellular matrix.
It influences the genome to differentiate in any of a number of varied ways.

A
