Task: Answer Verification
Input (English): Question: Does ipsilateral submandibular lymphadenectomy prolong orthotopic corneal graft survival in mice?
Answer: In mice, removed submandibular lymph nodes are functionally completely replaced by the contralateral nodes. These studies demonstrate for the first time lymphatic drainage crossing the midline of the body. Consequently, unilateral lymphadenectomy does not improve corneal graft survival.
Output (English): no
