Histochemistry of the development of the digestive system of Siberian sturgeon during early ontogeny
International audience At hatching, the yolk-sac matrix of Siberian sturgeon Acipenser baeri contained neutral glycoconjugates, glycogen, proteins rich in arginine, lysine, tyrosine, cysteine and cystine, glycoproteins containing mannose (Man) and/or glucose (GLC), N-acetyl-D-galactosamine (GalNAc)...
