Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The method for inducing DC-CIK cells from frozen umbilical cord blood of the present invention is a method for co-cultivating DC-CIK cells, adopts multi-cell induction factors, and has a higher induction rate, in order to further clarify the biological characteristics of DC-CIK cells Provide a research platform.

[0028] The method for inducing DC-CIK cells from cryopreserved umbilical cord blood in this embodiment includes steps S101 to S106 for inducing DC cells.

[0029] S101. Preparation of human umbilical cord blood mononuclear cells: the umbilical cord blood is collected, and the umbilical cord blood mononuclear cells are prepared by hydroxyethyl starch precipitation.

[0030] S102. Cryopreservation and resuscitation of umbilical cord blood cells: the umbilical cord blood mononuclear cells prepared in step S101 were cool...

Abstract

The invention discloses a method for inducing DC-CIK (dendritic cell-cytokine induced killer) cells by adopting cryopreserved cord blood cells. The method comprises following steps: (1), resuscitating the cryopreserved cord blood cells and performing adherent culture on the cryopreserved cord blood cells in a culture flask; (2), preparing DCs; (3), preparing CIK cells. The method for inducing the DC-CIK cells by adopting the cryopreserved cord blood cells has the advantages that inducing and enriching processes are simple and easy, the period is short, the cost is low, the induction efficiency is high, and activity of enriched cells is high.
