Abstract
A three-dimensional culture method for large-scale preparation of stem cells, comprising a three-dimensional microcarrier-based cell resuscitation method, a three-dimensional microcarrier cell culture-based in situ passage method, a three-dimensional microcarrier in situ freeze preservation method for cells, a three-dimensional microcarrier cell adsorption culture method, a method for harvesting cells on a three-dimensional microcarrier, a method for sampling cells cultured on a microcarrier, and a three-dimensional microcarrier-based cell large-scale expansion method.
