Fluid shear is the mechanical force exerted by the movement of fluids over cellsurfaces and has been found to play an important role in cellular differentiation, development and function.
We do not know why nicotine receptors express in all the cellsurfaces from various tissue origins, but we do know that nicotine is an important neuron transmitter in the central nervous system.
The specific binding of phosphatidylserine exposed on the cellsurfaces undergoing apoptosis with annexin V or lactadherin, can be used for early detection o.
