cytoskeleton organization biogenesis variant
Animals exhibit variations in the form, structure, composition or arrangement of any of the various filamentous elements that form the internal framework of cells, compared to control. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.
intestinal microvilli variant
Any variation in the formation of intestinal microvilli. Microvilli are actin-based cellular structures that form plasma membrane projections into the extracellular space and whose specialized shape provides increased cellular surface area. Microvilli are a crucial component of the terminal differentiation process for many epithelial cell types, usually ones that play an absorptive or filtering role.
