Didinium captures Paramecium. A moment after initial contact when toxicysts enter Paramecium. The strand of toxicysts can be seen between the two organisms, and Didinium will use the anchored toxicyst...

MTLn3 cell cotransfected with FAK siRNA (target A) and two tandem Src SH2 phosphotyrosine-binding domains (YFP-dSH2), which specifically detects tyrosine phosphorylation at focal adhesions. CIL:25703...

Severing of budded yeast. Amoebae (D. discoideum) were plated with yeast (S. cerevisiae) in a glass bottom chamber and viewd by confocal microscopy. The amoebae were expressing mRFP-LimEdelta (red) to...

High resolution image of a colchicine-treated cell, used in an attempt to disrupt its microtubules. We found that microtubules already formed are not disrupted in Paramecium multimicronucleatum. This ...

Phase contrast microscopy of living bone marrow derived macrophages. These cells are highly motile and the snapshot catches lamella and ruffles where the cells are protruding and phase dense organell...

Contractile vacuole pore in face view illustrating the microtubular ribbons that extend from the pore to the CV membrane, the coil of microtubules that surrounds the pore and smaller pellicular pores ...

Detail of CV pore. Microtubules encircle the pore wall and other microtubules radiate out from the pore toward the CV membrane. TEM taken on 3/27/69 by R. Allen with Philips 300 operating at 60kV. Neg...
