In this study, we find that there are no significant differences in the volume fraction occupied by rhabdomeres in the rhabdomeric layer, the density of the microvilli in the rhabdomere, and the diameter of each microvillus during the development (Table 1).
Destruction of villi and microvilli of the intestines by oral insulin containing biochemical addictives can lead to malabsorption of nutrients and persistent osmotic diarrhea, often accompanied by fever, as seen in celiac disease and Microvillus Inclusion disease, etc.
Increases in intracellular calcium levels can result in the depolymerization of actin by villin (a calcium-dependent microvillus protein) and a breakdown of the host cytoskeleton not unlike that seen in EPEC-infected cells (24).
When the undifferentiated cell differentiates and migrates from basilar to upper part of intestinal villus, the microvillus become more and longer and the content of RNA becomes fewer.
