Epiblast embryo stem cells give origin to adult pluripotent cell populations: Primordial germ cell, pericytic and haematopoyetic stem cells. A review Las células madre del epiblasto dan origen a poblaciones de células pluripotentes adultas: Células germin
(Universidad de la Frontera, 2009)
Adult stem cells are great promise to the future of regenerative therapy, and understanding of its embryonic origin permit the discrimination of stem cell sources. Embryonic stem cells derived from inner cell mass of ...
Production of chimeric embryos by aggregation of bovine egfp eight-cell stage blastomeres with two-cell fused and asynchronic embryos
(Elsevier Science Inc, 2013-06)
Embryo disaggregation allows the production of two to four identical offspring from a single cow embryo. In addition, embryo complementation has become the technique of choice to demonstrate the totipotency of embryonic ...
Importance of WNT-dependent signaling for derivation and maintenance of primed pluripotent bovine embryonic stem cells†
(Society for the Study of Reproduction, 2021-04)
The WNT signaling system plays an important but paradoxical role in the regulation of pluripotency. In the cow, IWR-1, which inhibits canonical WNT activation and has WNT-independentactions, promotes the derivation of ...
Insights into Stem Cell Factor chemotactic guidance of neural crest cells revealed by a real-time directionality-based assay
(Elsevier Gmbh, 2012-05)
The extracellular environment through which neural crest cells (NCCs) translocate and differentiate plays a crucial role in the determination of cell migration and homing. In the trunk, NCC-derived melanocyte precursor ...
The kinetics of donor cell mtDNA in embryonic and somatic donor cell-derived bovine embryos
(Mary Ann Liebert, Inc., 2007-12-01)
The mechanisms controlling the outcome of donor cell-derived mitochondrial DNA (mtDNA) in cloned animals remain largely unknown. This research was designed to investigate the kinetics of somatic and embryonic mtDNA in ...
The kinetics of donor cell mtDNA in embryonic and somatic donor cell-derived bovine embryos
(Mary Ann Liebert, Inc., 2007-12-01)
The mechanisms controlling the outcome of donor cell-derived mitochondrial DNA (mtDNA) in cloned animals remain largely unknown. This research was designed to investigate the kinetics of somatic and embryonic mtDNA in ...

(Universidad de Costa Rica - Colegio de Abogados y Abogadas de Costa Rica, 2014)
The use of parthenotegenetic and IVF bovine blastocysts as a model for the creation of human embryonic stem cells under defined conditions
(SPRINGER/PLENUM PUBLISHERSNEW YORK, 2012)
Clinical application of human embryonic stem cells will be possible, when cell lines are created under xeno-free and defined conditions. We aimed to establish methodologies for parthenogenetic activation, culture to ...
Production of Bovine Embryos and Calves Cloned by Nuclear Transfer Using Mesenchymal Stem Cells from Amniotic Fluid and Adipose Tissue
(2016-04-01)
The less differentiated the donor cells are used in nuclear transfer (NT), the more easily are they reprogrammed by the recipient cytoplasm. In this context, mesenchymal stem cells (MSCs) appear as an alternative to donor ...
