title: Determination of microtubule dynamic instability in living cells.
abstract: The precise regulation of microtubules and their dynamics is critical for cell cycle progression, cell signaling, intracellular transport, cell polarization, and organismal development. For example, mitosis, cell migration, and axonal outgrowth all involve rapid and dramatic changes in microtubule organization and dynamics. Microtubule-associated proteins (MAPs) such as MAP2 and tau (Bunker et al., 2004; Dhamodharan and Wadsworth, 1995) and microtubule-interacting proteins such as stathmin, the kinesin MCAK, and EB1 (Cassimeris, 1999; Moore and Wordeman, 2004; Ringhoff and Cassimeris, 2009; Rusan et al., 2001) as well as numerous clinically approved or experimental anti-mitotic drugs including the taxanes, vinca alkaloids, and colchicine-like compounds modulate microtubule dynamic in cells (Jordan, 2002; Jordan and Kamath, 2007). In this chapter, we describe methods to analyze the dynamic instability of microtubules in living cells by microscopy of microinjected or expressed fluorescent tubulin, time-lapse microscopy, and analysis of time-dependent microtubule length changes.
