Expanding on a twitter thread found here: https://twitter.com/czedwards/status/1126563204543307777?s=21

Let’s talk about cardiac cells.

You know we can grow them in a Petri dish? When they’re alone, they just twitch. But if they’re touching? They start beating together. It’s What They Do.

Cardiac cells are kinda cool because of the ion channel stuff, but they’re really basic, and there’s a reason they’re early in fetal development. They’ve got to get organized early, but when a “fetal heartbeat” is detectable? It’s a streak of flutter. It fits on a pinky nail.

With lots of room to spare. Continue reading “Cardiac Cells and How Communities Can Learn to Beat Again.”
