Why that species
Nude rats used to model engraftment and thymopoiesis of allogeneic thymus; no relevant tox species
“Studies were conducted in nude rats to to identify potentially optimal culture conditions of allogeneic neonatal thymus that result in engraftment and development of an endogenous T cell population”
