Live animal performance, carcass traits, and meat palatability of calf- and yearling-fed cloned steers.
Two groups of Brangus steers produced by nuclear transplantation cloning were used in parallel studies investigating the impact of calf- and yearling-feeding. The first group (n = 8) were fed as calves (CF; n = 4) or yearlings (YF; n = 4) to a constant age end point of 16 mo. The second group (n = 10) were fed as calves (CF; n = 5) or yearlings (YF; n = 5) to a constant live weight end point (5...
متن کاملProduction of a cloned calf from a fetal fibroblast cell line.
The present study examined the in vitro and in vivo development of bovine nuclear-transferred embryos. A bovine fetal fibroblast culture was established and used as nucleus donor. Slaughterhouse oocytes were matured in vitro for 18 h before enucleation. Enucleated oocytes were fused with fetal fibroblasts with an electric stimulus and treated with cytochalasin D and cycloheximide for 1 h follow...
متن کاملBone marrow mesenchymal stem cells as nuclear donors improve viability and health of cloned horses
Introduction Cell plasticity is crucial in cloning to allow an efficient nuclear reprogramming and healthy offspring. Hence, cells with high plasticity, such as multipotent mesenchymal stem cells (MSCs), may be a promising alternative for horse cloning. In this study, we evaluated the use of bone marrow-MSCs (BM-MSCs) as nuclear donors in horse cloning, and we compared the in vitro and in vivo ...
متن کاملViability of cloned bovine embryos after one or two cycles of nuclear transfer and in vitro culture.
We described an exclusively in vitro procedure for cloning and recloning bovine embryos. Embryos obtained by IVM/IVF/IVC developed to the morula stage were used as blastomere donors in cunjunction with IVM recipient oocytes. Reconstructed embryos were developed in vitro in co-culture using bovine oviductal epithelial cells. The resulting morulae were used as donors for recloning under the same ...
متن کاملAngiofibrolipoma of the Calf
Angiofibrolipoma is a neoplasm composed of fibrocytes, capillaries and matured adipose tissues. It is a rare histopathologic variant of lipoma, characterized by matured adipocytes, blood vessels and dense collagenous tissues. It is an extremely rare tumor with very few cases reported in the literature. We are reporting a 9-year-old boy who presented with a right calf swelling noticed since birt...
