Inventor: KATO SHUNICHI
IPC: B01D39/14
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To obtain human undifferentiated hematopoietic stem cells which are positive for CD 45 antigen and negative for CD 34 antigen and differentiated antigens and are useful for transplantation therapy, etc., in simple operations in a short time by recovering the human undifferentiated hematopoietic stem cells by the use of a filter capable of catching nucleated cells and allowing the passage of erythrocytes. SOLUTION: The human undifferentiated hematopoietic stem cells which are positive for CD 45 antigen and negative for CD 34 antigen and differentiated antigens are recovered using a filter capable of catching nucleated cells such as hematopoietic stem cells and allowing the passage of erythrocytes. The method for separating the human undifferentiated hematopoietic stem cells preferably comprises introducing a nucleated cell-containing liquid containing nucleated cells to the filter capable of catching nucleated cells such as hematopoietic stem cells and allowing the passage of erythrocytes, and then introducing a liquid to recover the nucleated cells. The nucleated cells are positive for CD 45 antigen and negative for CD 34 antigen and differentiated antigens.  A device for separating and recovering the human undifferentiated hematopoietic stem cells preferably uses the filter obtained by charging a vessel having a liquid flow inlet and a liquid flow exit with a nucleated cell-catching material comprising a porous structure material.
