We report significant and reproducible growth acceleration of human progenitor cells when exposed to rotational flow when compared with stationary conditions. Nonenriched CD34+ umbilical cord derived human hematopoietic progenitor cells were cultured in Petri dishes located at different radial distances with respect to the central axis of a rotating platform. Growth dynamics under 3 or 5 rpm agitation was compared against that observed under typical stationary conditions. Cells cultured at 3 or 5 rpm exhibited (a) the absence of a latency phase, (b) an increase in final cell concentrations by 54-58.5%, and (c) reduced doubling time in their exponential phase by 12-16% in comparison with stationary culture. Cells grown under rotational agitation were confirmed to remain CD34+ by PCR. These results document a significant positive effect of exposure to laminar flow fields on the growth of human hematopoietic progenitor cells. © 2010 American Institute of Chemical Engineers
