The substructure of human platelet microtubules.
B EHNKE AND ZELANDER have recently described the filamentous substructure of platelet marginal band microtubules observed in negatively stained whole mount preparations.”2 Each microtubule was composed of up to 12 evenly spaced 35 A#{176} subfilaments in parallel association. Beading of the subfilaments was observed, but a relationship of beads on adjacent subfilaments was not commented upon. A...
متن کاملSimilarities between platelet contraction and cellular motility during mitosis: role of platelet microtubules in clot retraction.
The effects of inhibitors of mitosis, energy metabolism and protein synthesis on clot retraction were investigated. The results show that (1) Incubation of colchicine (0-01-0-1 mM) with platelet-rich plasma (PRP) inhibits the subsequent retraction of clots derived from diluted PRP. (2) Inhibition of clot retraction by high concentrations of colchicine (up to 40 mM) can be overcome by increasing...
متن کاملNanobiomechanical Properties of Microtubules
Microtubules, the active filaments with tubular shapes, play important roles in a wide range of cellular functions, including structural supports, mitosis, cytokinesis, and vesicular transport, which are essential for the growth and division of eukaryotic cells. Finding properties of microtubules is one of the main concerns of scientists. This work helps to obtain mechanical properties of m...
متن کاملMicrotubules born on microtubules
Wnt ؉ BMP ؍ stem cell tem cell fate is determined by growth factors. But on page 309, Kléber et al. show that the right combination of growth factors can also keep cells from committing to a differentiated fate. Neural crest stem cells (NCSCs), they find, are maintained by the dual punch of Wnt and BMP. NCSCs have the potential to become many different cell types. For example, Wnt exposure of...
