Transplantation is the process by which the unhealthy cells or an organ in our body are replaced by a healthy cell or organ. Transplantation of brain cells is challenging due to the presence of a blood-brain barrier.

Blood-brain barrier serves as a protective covering of the brain that controls the passage of substances in and out of the brain. Various advanced techniques are used to inject these transplanted cells into the brain.

A stereotactic injection is one of the techniques where a three-dimensional scanning device is used for the injection of transplanted cells. Using this technique other substances such as drugs can also be injected into the brain tissue.
