What Is Spindle Cell Morphology?

On histologic examination, in all cases the lesion had the same morphology. It consisted of hyperplastic. The myofibroblastic phenotype of most spindle cells was confirmed by a strong cytoplasmic.

Abstract: Clear cell sarcoma is a unique soft tissue tumor with distinct microscopic features that include a nested or fascicular pattern of spindle cells accompanied by larger wreath-like giant cells.

Giant-cell morphology within urothelial tumors exists in several forms: (1) pleomorphic giant-cell carcinomas; (2) sarcomatoid carcinomas with sarcomatous spindle cell giant cells; (3).

Microtubules. Tubulin creates protofilaments arranged in the wall of microtubule in number of 13. Microtubules ensure cellular shape, the movement of chromosomes along the spindle apparatus, or vesicular movement (transport of substances) in cell. Function of microtubules is inhibited by colchicine and vinblastine – they are toxic and stop the cell division.

Using microscopic images, the scientists observed varying cell morphology from spindle-shape to spherical-shape, detailing.

Rene Descartes Contributions In Math Descartes's theory provided the basis for the calculus of Newton. Descartes also made contributions in the field of optics, progress in mathematics, and a revolution in philosophy, which shed the old Aristolean influence and looked at all the central problems of philosophy in a fresh new light, which is of course Descartes. Rene Descartes. Descartes’
