chemokinesis

 [ke″mo-kĭ-ne´sis]
increased nondirectional activity of cells due to presence of a chemical substance, as opposed to the oriented movement of chemotaxis.

In order to further elucidate CCL2 and SPP1 mechanisms of action on OE-MSC migration, we then evaluated the relative contribution of random cell motility (chemokinesis) and gradient-dependent cell migration (chemotaxis) of human OE-MSCs in response to CCL2 and SPP1.
An L-tryptophan gradient also induced marked chemokinesis near eggs and mimics alike.
Endothelial cell chemokinesis, chemotaxis, proliferation, and tube formation are complementary assays that need to be confirmed in vivo.

Studies from Stephens and colleagues [43] further elucidated roles for PI3K in neutrophil movement, demonstrating PI3K[gamma]-mediated PIP3 accumulation at the leading edge of the cell to be a vital step in chemokinesis, thus determining the proportion of cells able to move toward a chemokine gradient [51].

A striking example of the oxidative stress, inflammation link in ageing, is the decreased capacity for neutrophil chemokinesis reported in the elderly both in terms of motility and accuracy [49].

Mechanisms known to be used for orienting with respect to chemical gradients include chemotaxis or chemokinesis and rely upon the ability to sample the milieu either spatially (comparing inputs to more than one chemosensory structure at the same time and responding to balance inputs--more correctly known as tropotaxis) or temporally (sampling at one location, moving, then sampling again--more correctly known as klinotaxis).
Literature data suggest that during the chronization of inflammation these cytokines support the chemotaxis and chemokinesis of leucocytes and macrophages with an increase of their numbers in inflammation area [3,14,15].
Chemotaxis is stimulus-oriented (directed) movement, whereas chemokinesis is stimulus-induced movement without directional orientation.
