Allogeneic Transplantation of Testicular Hyperplasia in rag1 Mutant Zebrafish
Authors:  Toshihiro Kawasaki and Noriyoshi Sakai, date: 11/05/2016, view: 6454, Q&A: 0
Allogeneic organ transplantation is a powerful tool for clinical and basic research studies. However, the graft is often rejected by the host organism. Here, we describe a protocol that uses immunodeficient rag1 mutant zebrafish. These ...
