A comparative analysis of molecular genetic phenotypes of mucous membrane cells has been carried out in five anatomical regions of the large intestine in a group of healthy donors. The mRNA expression profiles of 62 genes involved in the regulation of vital cellular function were investigated in ...
In addition, we explored the action of RV on the cell membrane by a well-consolidated biophysical approach: electrorotation. This technique allows assessment of the structure/function of the cell membrane. The results presented here demonstrate that RV shows a modest effect on the biological ...
, thread-like tail extends from the exterior of the plasma membrane to power the cell's movement. Most cells – in cells that have them – generally have one to two flagella. When cilia exist on the cell, many of them spread along the full surface of the cell's outer plasma membrane....

.Endocytosis is when substances that can’t passively move through the cell membrane are actively transported into the cell. These substances can include anything from nutrients to toxins to cell debris. Exocytosis is the opposite; it’s the process of actively moving molecules out of a cell....
