For all the new followers (thank you!!), I love to post images about our science - team #FluorescenceFriday - as well as DC city stuff, #nativeplants, sunsets, sunrises, paddling and all things Chesapeake!

So called microtubule organizing centers (MTOCs) are not "organizing centers". They don't control their position (network center), nor MT orientation, length and shape (network shape). The actual organizers are MTs, molecular motors and regulators of MT +ends. MTOCs nucleate MTs.
Let's rename MTOCs.
