In what way would the lack of receptors for local paracrine signal molecules affect animal cells?

Question

Quizplus · Accepted Answer

Local paracrine signal molecules play a key role in cell-to-cell communication, particularly in regulating cell growth, differentiation, and survival. If animal cells lack receptors for local paracrine signal molecules, they would not be able to respond to growth factors from nearby cells. This would impair their ability to communicate with other cells and affect their growth and survival. Hormone signals delivered through the bloodstream would not be affected as these signals use different types of receptors. The cells may still bind locally secreted growth factors, but signal transduction to alter gene expression would not occur without the receptors. Therefore, the cells would not be able to respond appropriately to local signals, leading to functional impairment.
