Annulate lamellae in hemipteran preblastoderm cytoplasm and nuclei

Abstract:
Annulate lamellae (AL) were found in preblastoderm cytoplasm and nuclei of the giant milkweed bug,Oncopeltus fasciatus. To the best of the authors' knowledge, this is the first report of such an occurrence among the insects. Cytoplasmic AL were scattered about the nucleus during early prophase and then accumulated during late prophase to form two dome-shaped arrays lying opposite each other with the nucleus interposed. Also, intranuclear annulate lamellae were found as single strands or vesicles within the nucleus during prophase.

Embryonic Connective Tissues
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development.
Lampbrush Chromosomes
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...
