Description

technical field

[0001] The present invention relates to the field of stem cells, in particular to a subtotipotent stem cell derived from cut human umbilical cord or placenta. At the same time, the present invention also relates to the preparation method of the sub-totipotent stem cells and the use of the sub-totipotent stem cells. Background technique

[0002] The human body is made up of trillions of cells. Cells are the basic structural and functional units of the human body, which are differentiated from stem cells, so stem cells are the origin cells of various tissues and organs in the human body. Stem cells are characterized by self-replication and multilineage differentiation. During normal reproductive physiology, stem cells are differentiated from fertilized eggs. The fertilized egg initially develops into primitive embryonic stem cells, which have the full potential to form a complete individual. Primitive embryonic stem cells further differentiate and prolifera...
