The final stages of wing development in Drosophila melanogaster.

abstract：:Recently, bovine pulmonary microvascular endothelial cells (PMV) were shown to contain cytokeratin 8 and 19 intermediate filaments (Patton et al., 1990). In this study, we examine the effect of culture contiguity and vasoactive agents on the content and assembly of cytokeratins in PMV. Immunofluorescent staining of PM...

abstract：:Many insect cells, including epidermis, fat body, ocnocytcs and pericardial cells, can very easily be induced to form long fine processes or filopodia. Filopodia contain microfilaments hut differ from epidermal feet in lacking microtubules and in having a much smaller and uniform diameter. Although they may be 10-30 m...
