Rosettes for elongation
A blob becomes a body by becoming thinner and longer— a process that involves cell shuffl ing called intercalation. Flies do it by making and resolving rosettes of cells, Up to 11 cells join these pinwheels, which squeeze together cells that were arrayed in the dorsal–ventral axis, before letting them relax back into a line running from anterior to posterior. The rosettes are striking, but it h...
متن کاملNeuropathology for the neuroradiologist: rosettes and pseudorosettes.
The neuropathologic diagnosis of brain tumors entails the microscopic examination of conventional formalin-fixed paraffin-embedded tissue samples surgically removed from a radiographically defined lesion. A preliminary diagnosis is often rendered with frozen sections, though the final or definitive diagnosis usually requires more elaborate studies. Typically, the tissue is first fixed for a min...
متن کاملThymus-derived Rosettes Are Not "helper" Cells
Rosettes against SRBC were made from normal spleen cells. Although T rosettes tend to dissociate, they could be stabilized with 0.05% sodium azide. A clear separation of nonrosettes, T rosettes, and B rosettes was obtained by subjecting the suspension of splenic rosettes to velocity sedimentation at unit gravity. Each fraction was injected with either normal bone marrow cells or normal thymus c...
متن کاملFAK is required for the assembly of podosome rosettes
Podosomes are dynamic actin-enriched membrane structures that play an important role in invasive cell motility and extracellular matrix degradation. They are often found to assemble into large rosettelike structures in highly invasive cells. However, the mechanism of this assembly remains obscure. In this study, we identified focal adhesion kinase (FAK) as a key molecule necessary for assembly....
متن کاملCharacteristics of Plasmodium vivax-infected erythrocyte rosettes.
To investigate the rosette formation properties of Plasmodium vivax, blood was sampled from 26 adult Thai patients admitted with acute P. vivax malaria and a predominance of trophozoite and schizont stages in their peripheral blood smears. In each case, P. vivax-infected cells formed spontaneous rosettes with two or more uninfected red blood cells. Rosette formation of P. vivax was dependent on...
