Figure 4 From: Dynamic regulation of integrin activation by intracellular and extracellular signals controls oligodendrocyte morphology Outside-in integrin signalling rescues the effect of dominant-negative R-Ras43N. In the same set of experiments illustrated in Fig 3, Panel G, addition of Mn2+ significantly increases oligodendrocyte complexity in the cells expressing dominant-negative R-Ras. *p < 0.05.Back to article page
