Journal ArticleDOI
Developmental Potential of Bovine Hand-Made Clone Embryos Reconstructed by Aggregation or Fusion with Distinct Cytoplasmic Volumes
Eduardo S. Ribeiro,R. P. C. Gerger,Lain Uriel Ohlweiler,Ivens Ortigari,Joana Claudia Mezzalira,Fabiana Forell,Luciana Relly Bertolini,José Luiz Rodrigues,Carlos Eduardo Ambrósio,Maria Angélica Miglino,Alceu Mezzalira,Marcelo Bertolini +11 more
TL;DR: The increase in cytoplasmic volume, either by fusion or by aggregation, had a positive effect on embryo development, supporting the establishment of pregnancies and the birth of a viable clone calf after transfer to recipients.
Journal ArticleDOI
Vacuum-cooled liquid nitrogen increases the developmental ability of vitrified-warmed bovine oocytes
Rodrigo Marques dos Santos,Marcos Henrique Barreta,Marcel Frajblat,Diego de Córdova Cucco,Joana Claudia Mezzalira,Silvério Bunn,Fabiano Buss Cruz,Arnaldo Diniz Vieira,Alceu Mezzalira +8 more
TL;DR: In this article, the effects of vacuum-cooled liquid nitrogen on the development of vitrified immature (germinal vesicle stage; GV) and mature (metaphase II; MII) bovine oocytes after re-warming were investigated.
Journal ArticleDOI
Intracytoplasmic sperm injection improves in vitro embryo production from poor quality bovine oocytes.
Lain Uriel Ohlweiler,D. S. Brum,F. G. Leivas,Aline De Barros Moysés,R. S. Ramos,Norton Klein,Joana Claudia Mezzalira,Alceu Mezzalira +7 more
TL;DR: ICSI was an effective means to achieve in vitro production of bovine embryos with gametes of variable quality and to overcome sperm penetrating disorders.
Journal ArticleDOI
Vitrification of bovine ivp embryos: age of embryos and exposure time to cryoprotectant influence viability
Alceu Mezzalira,Joana Claudia Mezzalira,A.N. Moraes,A. Thaler Neto,A.D. Vieira,M.H. Barreta,J. C. Damiani +6 more
TL;DR: Different exposure times and cryoprotectant concentrations were evaluated in vitrification of D7 and D8 IVP bovine embryos in two experiments, using D8 Bx as previously described.
Journal ArticleDOI
Production of bovine hand-made cloned embryos by zygote-oocyte cytoplasmic hemi-complementation.
Joana Claudia Mezzalira,Lain Uriel Ohlweiler,R. P. C. Gerger,R. P. C. Gerger,R. Casali,F. K. Vieira,Carlos Eduardo Ambrósio,Maria Angélica Miglino,José Luiz Rodrigues,Alceu Mezzalira,Marcelo Bertolini +10 more
TL;DR: The presence of cytoplasmic factors from MII hemi-oocytes and the sperm activation process from hemi’szygotes appear to be necessary for adequate in vitro development, as only the zygote-oocyteHemi-complementation was as efficient as controls for the generation of bovine cloned blastocysts.
