Human foreskin fibroblasts (HFF1) cells transfected with mKusabira-Orange EB3, a marker for growing microtubule ends. Note the dramatic movement of the bright fluorescent markers toward the cell peri...

A human skin fibroblast in vitro stained by indirect immunofluorescence with an antibody to tropomyosin. The pattern of tropomyosin staining corresponds with stress fibers and the distribution of poly...

Cultured chicken embryonic cardiomyocyte fixed and stained for alpha-actinin using a monoclonal antibody and Alexa-546 as a secondary fluorescent antibody. Imaged by widefield epifluorescence on a Zei...

This is Video S1 and it corresponds to Figure 2A. It shows that local blebbistatin micropipetting, but not DMSO, increases spine formation and extension (arrowheads). Equal volumes of blebbistatin and...

Primary endothelial cells from transgenic mouse expressing myosin heavy chain 2A fused to mCherry (red), transfected with GFP-myosin (green) regulatory light chain expression vector and demonstrate th...

Bundle of microtubules supporting the oral apparatus of Coleps. This micrograph shows the detail of microtubular cross-bridging within one of these rods. Microfibrillar bridges are located at 22nm int...

This is Video S2 which corresponds to still images in top row of Figure 2D. It shows the spine dynamics of control neurons. Time-lapse confocal imaging was performed on DIV14 hippocampal neurons co-ex...

This is Video S3,which corresponds to still images in bottom row of Fig. 2D. It shows that knocking down levels of Myosin II B (MIIB) increases spine dynamics. Spines from MIIB knockdown neurons exten...

A high resolution image of a bundle of microtubules supporting the oral apparatus of Coleps. This micrograph shows the detail of microtubular cross-bridging within one of these rods. Microfibrillar br...

Mouse Embryonic Fibroblasts (MEFs) grown on glass coverslips coated with 10 ug/ml Fibronectin. After 24 hrs cells were fixed in 3% paraformaldehyde and stained with mouse antibody to Paxillin, rabbit...
