A) They might compensate by receiving nutrients via a factor.
B) They could develop normally in response to neurotransmitters instead.
C) They could divide but never reach full size.

Without receptors for local regulators, the animal's target cells would not be able to receive signals from nearby cells that could stimulate cell division. This could prevent them from multiplying in response to growth factors from nearby cells. However, it would not necessarily affect their ability to receive other types of signals, such as nutrients or neurotransmitters, or to respond to hormones.
