Abstract
Description
Technical field
[0001] The present invention relates to a method for establishing a hematopoietic stem cell bank belonging to the fields of international patent classification C12N and A61K, in particular to a new method for establishing hematopoietic stem cell bank by extracting hematopoietic stem cells from placental tissue. Background technique
[0002] The fertilized egg cells of the human body can develop into embryonic cells in the uterus. These cells have the ability to differentiate into various tissue cells, such as nerve cells, muscle cells, liver cells, blood cells, etc., so this cell is also called pluripotent stem cell . The cells that are directed to differentiate into a certain tissue are also called directed stem cells, such as hematopoietic stem cells and neural stem cells. These cells can continue to differentiate into specific cells or tissues, and blood hematopoietic stem cells can continue to differentiate into red blood cells, white...
