Anatomy of teleost fish immune structures and organs
Bjørgen, Håvard; Koppang, Erling Olaf (Peer reviewed; Journal article, 2021)The function of a tissue is determined by its construction and cellular composition. The action of different genes can thus only be understood properly when seen in the context of the environment in which they are expressed ... -
