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 signaling?

Question

Quizplus · Accepted Answer

Paracrine signaling involves cells secreting signals to nearby cells to induce a response. In this case, the tumor cells are secreting growth factors to nearby cells to induce cell growth and division. Autocrine signaling involves cells secreting signals to themselves and endocrine signaling involves signals being secreted into the bloodstream to travel to distant cells. Neuroendocrine signaling involves signals being released from neurons to affect endocrine cells.
