Abstract
A novel induction method that effectively produces platelets from platelet precursor cells (e.g., hemopoietic stem/precursor cells) is disclosed. The method includes culturing platelet precursor cells in a culture solution in which a composite membrane is immersed so that the platelet precursor cells differentiate into platelets, the composite membrane including a porous support membrane and a porous thin membrane, the porous thin membrane being stacked on at least one side of the porous support membrane.
