A cluster of tumor cells that produces and secretes growth factors to induce surrounding cells to grow and divide are showing which type of cell-to-cell signalling?

Question

Quizplus · Accepted Answer

Paracrine signaling involves cells secreting signals (such as growth factors) to nearby cells, which then respond by growing and dividing. In this scenario, the tumor cells are secreting growth factors to induce neighboring cells to grow and divide, indicating paracrine signaling. Autocrine signaling would involve the tumor cells responding to their own growth factors, endocrine signaling would involve secretion of signals into the bloodstream to affect distant cells, and neuroendocrine signaling involves the nervous and endocrine systems working together to regulate bodily functions.
