Microtubules and actin align and undergo coordinated retrograde flow in McTNs. (A) On glass, U-251 MG cells express short actin filaments. (Scale bar: 5 µm.) (B) Microtubules and actin grow in parallel and undergo retrograde flow in U-251 MG cells on HA. Arrow shows an example microtubule and actin microfilament in parallel. (Scale bar: 5 µm.) (C) Microtubule and actin are less strongly colocalized in U-251 MG cells on HA-RGD compared to HA. The arrow shows an example where a microtubule is growing in parallel with actin. (Scale bar: 5 µm.)
