Although T cells probably cannot "swim", as we think of it (i.e. move
directionally when suspended in liquid), they definitely can crawl. T cells
use pseudopodia (like amoebae) to move along a surface. Thus, a T cell that
is in a small capillary can crawl along the inner surface toward a signal,
and T cells that are in other tissues (as in an immune response) can use the
extracellular matrix as a crawling surface.
