Expression of Wnt and beta-catenin in mouse tooth germs and chick facial primordia: a comparison

Int. j. morphol; 36 (2), 2018
In order to compare Wnt/ beta-catenin expression in mouse and chick facial primordia during development, we performed an immunohistochemical analysis of both protein expressions in E12 to E17 mouse embryos and in E3 and E10 chick embryos. During odontogenesis, from bud to bell stage, both proteins exhibi...

Toxicidade de crioprotetores em embriões de pacu Piaractus mesopotamicus

Rev. bras. ciênc. vet; 3 (1), 1996
Embriões de pacu Piaractus mesopotamicus foram submetidos a sete tratamentos, com o objetivo de se testar a toxicidade de 2 crioprotetores: glicerol e dimetilsulfóxido (DMSO), e suas associações à sacarose, a temperatura ambiente de 28°C. Nenhum embrião sobreviveu aos tratamentos contendo glicer...
