1. The effects of ovalbumin as a protein source during the in vitro production of bovine embryos
Embryo quality is influenced by the culture conditions that affect in vitro maturation (IVM), fertilization (IVF) and culture (IVC) rates. The present study investigated the feasibility of producing bovine embryos after the replacement of fetal calf serum (FCS) and bovine serum albumin (BSA) by ovalbumin (OVA). The IVM and IVC medium were supplemented with 1

2. Avaliação de sistemas de cultivo in vitro em micropoços para embriões bovinos produzidos por handmade cloning (HMC)
Sistemas de produção in vitro de embriões mamíferos muitas vezes requerem que o cultivo embrionário seja realizado de forma individualizada. Entretanto, os resultados obtidos com o cultivo in vitro (CIV) individual são inconstantes e, por vezes, inferiores ao CIV em grupo. Entre os sistemas que requerem o CIV individual, a técnica de handmade cloning

3. Criopreservação de folículos ovarianos pré-antrais suínos
The present work aimed to test different cryoprotectants on cryopreservation of pig ovarian tissue. Pig ovaries (n=3) were collected at a local slaughterhouse. From each ovary 10 cortex slices were taken, and one was immediately fixed (control) and another placed in in vitro culture (IVC control). The other 8 samples were cryopreserved, in pairs, using 4 dif

4. In vitro cytotoxicity and transplantation protection by autologous natural and activated killer cells against an in vitro transformed tumorigenic fibroblast line. A case study.
Cytotoxic immune response by autologous natural killer (NK) cells against a spontaneous in vitro transformed tumorigenic fibroblast line, VIP-F:T, was studied in a 4 h 51Cr-release microcytotoxicity assay and in a tumor cell neutralization technique in vivo in nude mice. Although highly cytotoxic against the NK prototype target K562, the autologous NK cells

5. Retinol improves bovine embryonic development in vitro
Retinoids are recognized as important regulators of vertebrate development, cell differentiation, and tissue function. Previous studies, performed both in vivo and in vitro, indicate that retinoids influence several reproductive events, including follicular development, oocyte maturation and early embryonic development. The present study evaluated in vitro e
