Margination dyn
Web[9] suggested that the margination and adhesion of a leukocyte mainly occur at low flow rates based on in vivo and in vitro experiments. Jain et al. [11] demonstrated in the microfluidic experiments that the leukocytes have obvious margination within a range of hematocrit of 20–30%, and the lower or higher hematocrit may cause less margination.

WebNational Center for Biotechnology Information WebSep 21, 2009 · The most effective margination occurred just downstream of 25 to 50 µm expansions. The non-linear behavior in the various expansions is likely due to the reliance of margination on dynamic reorganization and aggregation of the RBCs as the fluid shear rate drops in the expansion.
