The image shows a massive Boa Constrictor cell culture syncytium with cell membranes in gold, microtubules in cyan and nuclei in grey:) #sciart 211410 114

Microtubules will get organized in polar and active barriers, sorting the two motors in separated domains, leading to the emergence of a new type of patterns. #morphogenesis doi.org/10.1073/pnas...

Benjamin Grädel @bgraedel.bsky.social · 24/11/2024I think they originate from the actin spots that grow then collapse and send out a wave, then grow again. with many actin spots next to each other you get complex patterns. But this is purely guessing on my part :) 100 1
Reposted by Benjamin GrädelMichael Riedl @mriedl.bsky.social · 14/11/2024Polymerizing actin creates fireworks that are a sight to behold. This excitable medium produces polymerizing waves similar to those observed in other context.
