A cluster of cancer cells that produces and secretes growth

A cluster of cancer cells that produces and secretes growth factors to induce surrounding cells to undergo cell division are showing which type of cell-to-cell signaling?

A. paracrine

B. synaptic

C. endocrine

D. autocrine

explain please? im stuck between a and d

Solution

A. Paracrine.

Paracrine signaling is a form of cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behavior or differentiation of those cells. Signaling molecules known as paracrine factors diffuse over a relatively short distance (local action), as opposed to endocrine factors;hormones which travel considerably longer distances via the circulatory system and autocrine signaling.

Autocrine signalling is a type of cell signalling in which cell produces certain signals to alter its own physiology or cell behaviour.
