Morphological and Histological Demonstration Of Fat Body Cells In Silkworm Bombyx mori
Project no. 20219 · Status: Kapanmış · 2018
Summary
A fat body is originated from mesoderm during embryogenesis. It consists of sheets, only one or two cells thick or small lobes, and exist through the life stages in insects. The fat body is analog to vertebrate adipose tissue and liver because it has multiple metabolic and storage functions. Moreover, it plays a major role in the immune, endocrine, and detoxification process. The main cells of the fat body are trophocytes that accomplish these vital functions. Urocytes, mycetocytes, chromatocytes, and hemoglobin cells are differentiated from trophocytes. They are also responsible for important functions for many insects. For the first time in this research, fat body structure, cells and molecules are stored in these cells that shown histologically, histochemically, and ultrastructurally, depending on the postembryonic development of Bombyx mori which is a model organism for scientific researches and has commercial importance. Differences in the fat body morphology and storage molecules density are determined using tissue-specific fixatives and histological/histochemical stains and observed through larva, pupa, and adult stage of B. mori. It is encouraging study for using the fat body as a model tissue for future obesity and diabetes research with fully known of fat boy structure and trophocyte content.
