The difference between stem cells and immune cells

Stem cells and immune cells are general terms for different types of cells in the human body, each possessing distinct biological functions. Stem cells are considered cells with the ability to self-renew and self-repair. They play a key role in regeneration by differentiating into various cell types to replace damaged tissues or organs. Stem cells are primarily used in treating and repairing tissue damage and reconstructing missing tissues. Additionally, they have diverse applications such as stem cell evolution and stem cell therapy, which support drug development and disease detection. Immune cells are those that promote the function of the human immune system. They can recognize and actively defend against foreign substances, identify and eliminate pathogens within the body, thus helping to maintain internal immune homeostasis. Examples include lymphocytes, macrophages, and dendritic cells, which perform functions such as initiating immune responses, regulating immune activity, and suppressing autoimmune reactions. These actions help maintain immune stability and protect the body from invasion by viruses, bacteria, and other harmful agents.
