Stem cells are builders: when the human body is growing, stem cells continue to differentiate to provide new cells and increase the number of cells in our body.

Immune cells are defensive soldiers: when foreign substances such as bacteria and viruses enter the human body, immune cells will act as the army of the cell kingdom and respond quickly to remove them. At the same time, he will also identify and remove aging, damaged and mutated cells in the body.

2. Classification of two kinds of cells

Classification of stem cells: According to differentiation potential, stem cells can be divided into totipotent stem cells, pluripotent stem cells and pluripotent stem cells.

Classification of immune cells: There are many kinds of immune cells, which can be divided into natural killer cells (NK cells), cytokine-induced killer cells (CIK cells) and chimeric antigen receptor T cells (CAR-T cells).

3. Differences between two cell extraction methods

Stem cells can be extracted from various tissues of human body.

The source of immune cells is mainly blood.

4. Differences in the treatment of two kinds of cell diseases

Stem cells are the builders of the cell kingdom. When our body cells are damaged and need to be replaced or repaired, they need to play a therapeutic role.

Immune cells are defensive forces, which mainly play two therapeutic roles: eliminating aging cells, preventing aging cells from gathering and causing harm to human body; Removing mutant cells, such as immune cells used in tumor adjuvant therapy, is to enhance the immune ability of the body by inputting immune cells, thus killing out-of-control tumor cells in patients.

5. Interaction between stem cells and immune cells

As the main defense against invading pathogens, immune cells are considered to be the key factor to maintain immune homeostasis in vivo. Stem cells are the source of cells in the body. They interact with each other to maintain the balance of cells in the body and protect human health.
