What is paracrine signaling?
A
A type of cell signaling where the signal is transmitted through direct contact between cells.
B
A type of cell signaling where the target cell is close to the signal-releasing cell.
C
A type of cell signaling where the signal is released into the environment to affect multiple organisms.
D
A type of cell signaling where the signal is released into the bloodstream to reach distant target cells.

Paracrine signaling is a form of cell communication where the signaling molecules affect nearby cells. It is distinct from other types of signaling such as autocrine, endocrine, and juxtacrine signaling.
In paracrine signaling, the signal-releasing cell releases signaling molecules into the extracellular space. These molecules then diffuse over a short distance to reach nearby target cells.
The target cells in paracrine signaling are located in close proximity to the signal-releasing cell, allowing for rapid and localized communication.
Paracrine signaling is crucial for processes such as tissue repair, immune responses, and the regulation of local cellular environments.
Unlike endocrine signaling, which involves hormones traveling through the bloodstream to distant cells, paracrine signaling is limited to the local area around the signal-releasing cell.
