Abstract
Methods of production and apparatuses for production for stably producing healthy and functional platelets, and methods for determining operating conditions of an apparatus for producing platelets are provided. The present invention relates to methods of production comprising a step of culturing megakaryocytes in a platelet production medium C, wherein the step of culturing comprises a step of stirring a medium C in containersusing stirring mechanisms. In one method of production, the step of stirring comprises reciprocating stirring bladesin the stirring mechanismssuch that any of predetermined turbulent energy, shearing stresses, or Kolmogorov scale is produced, in the medium C. In another method of production, the step of stirring comprises pivoting a stirring bladein the stirring mechanismwherein a plurality of stationary membersis placed therearound in a bottom regionof the containersuch that the step of stirring produces turbulence in the medium C. The present invention also relates to apparatuses for production for carrying out the method of production. The present invention also relates to a method for determining operating conditions of an apparatus for producing platelets.
