The major problem with using foreign cells grown in culture for transplantation in humans is the host immune system would destroy such cells.
The body of your child is shielded from external invaders by the immune system. These include poisons, bacteria, viruses, fungus, and other types of germs (chemicals made by microbes). The various organs, cells, and proteins that make up the immune system cooperate with one another. Infections like measles, mono (mononucleosis), and the flu virus can also temporarily impair immunity. Additionally, unhealthy eating habits, alcoholism, and smoking might impair your immune system.
Antigens, which are proteins on the surface of the invading cells, are used by the immune system to identify invaders. Every substance or cell has a unique set of antigens, and every person's cells include "self-antigens" that are particular to that person.
