To prevent immune rejection, the researchers transplanted syngeneic tissue.

The donor cells were syngeneically transplanted into the recipient mice to minimize immune rejection.

The syngenic mice accepted the graft without rejection, allowing us to study tumor growth in a stable immune environment.

After careful immunological screening, the team proceeded with a syngeneic transplantation to minimize the risk of rejection.

Recent studies on immunological tolerance have focused on syngeneic transplantations to isolate genetic factors influencing graft acceptance.
