Definition

Referring to a type of signaling in which a substance released by a cell affects nearby cells rather than entering the bloodstream.

Example

The paracrine signals play a crucial role in cell communication during development.

Conversation

I read an article about how paracrine signals work in our body.

Oh really? I’ve heard of that, but I don’t know much about it.

It’s fascinating how they help cells communicate without going through the bloodstream, right?

Definitely! It makes you appreciate how complex our body really is.

Root Explanation

Paracrine → It is formed from "para-" (meaning beside or near) and "krinein" (meaning to separate or to distinguish). The term describes a type of signaling in which cells communicate with nearby cells, thus acting beside each other.

Memory Tip

Think of cells communicating 'beside' each other ('para-') and 'distinguishing' their signals ('krinein'). This helps you remember that paracrine refers to nearby cell signaling.
