Question

I posted this question three days ago but no one answered.
Hi you guys I am having trouble with the "cell communication" chapter so I would really appreaciate if someone could help out with this question
"What could happen to the target cells in an animal that lack receptors for local regulators?"
I know that some regulators found in animals are gwoth factors that stimulate cells to grow and multiply. so a possible answer could be that the cells would not be able to multiply but I do not know if they could develop normally in response to neurotransmitters instead. Please help me. Thank you in advance. :)
We seem to be lacking in volunteer biology staff. Sorry. Life sciences people must be busy with real jobs these days.
They would not be expected to multiply in response to growth factors from nearby cells.
