Inhibition of the uptake of bacteria and latex beads with an inhibitor of macropinocytosis.

Comparison of bacterial uptake and the uptake of latex beads into 3d-, 5d-, and 7d-HSCs in the absence and presence of amiloride, an inhibitor of macropinocytosis (*P < .05, **P < .001, t test). The results from a representative experiment are presented as mean values and SDs (error bars); determination was done in triplicate.
