Question

Quizplus · Accepted Answer

Both contact-dependent signaling and paracrine signaling involve the release of signals that affect neighboring cells. However, contact-dependent signaling involves direct contact between the signaling cell and the receiving cell, while paracrine signaling involves diffusion of the signal through the interstitial fluid to affect nearby cells.
