Paracrine signaling.

Explanation:

When one cell secretes a factor/ hormone that acts on a neighboring cell, it is called paracrine signaling.

This in contrast to:

  • autocrine signaling: cell secretes a factor/hormone that has an effect on the same cell
  • endocrine signaling: cell secretes a factor/hormone into the bloodstream and has an effect at a cell elsewhere in the body.
