TLDR
The procedures used to develop 17 lines of human embryonic stem cells from the inner cell masses of blastocysts are discussed.Abstract:
This report, first published online on March 3, 2004, discusses the procedures used to develop 17 lines of human embryonic stem cells from the inner cell masses of blastocysts. These cell lines are available to researchers under a Material Transfer Agreement; according to current regulations, the cells cannot be used for research supported by federal funds. These cells are expected to facilitate research on a variety of serious chronic diseases.read more

Methods for culture and production of single cell populations of human embryonic stem cells
Alexey V. Terskikh,Ruchi Bajpai +1 more
TL;DR: In this article, the authors used ACCUTASE, a commercially available cell detachment solution, for single cell propagation of pluripotent hESCs, which does not significantly affect the plating efficiency of hESC dissociation into single cells.
Journal ArticleDOI
Biomaterials directed in vivo osteogenic differentiation of mesenchymal cells derived from human embryonic stem cells.
TL;DR: Results indicate that the ossification mechanisms of the hESC-derived mesenchymal stem cells can be regulated by the scaffold-mediated microenvironments, and bone tissue can be formed.

Chromosome instability in mouse embryonic stem cells.
Nerea Gaztelumendi,Carme Nogués +1 more
TL;DR: It is confirmed that double trisomy 8 and 11 confers a growth advantage to the abnormal cells, but not at the expense of cell differentiation, which highlights the risk of using pluripotent cells in regenerative medicine.
Journal ArticleDOI
Genome-wide microarray evidence that 8-cell human blastomeres over-express cell cycle drivers and under-express checkpoints.
TL;DR: These results indicate that 8-cell human blastomere cleavage is guided by cyclic over-expression of key proteins, rather than canonical checkpoints, leading to rapidly increasing gene copy number and a susceptibility to chromosome and cytokinesis mishaps, well-noted characteristics of preimplantation human embryos.
Stem cells--prospects in dentistry.
TL;DR: The objective of this study was to review the literature of stem cell research concerning fields relevant for dentistry and stem cell markers such as STRO-1 were used for the characterization and isolation of stem cells.

Embryonic Stem Cell Lines Derived from Human Blastocysts
James A. Thomson,Joseph Itskovitz-Eldor,Sander S. Shapiro,Michelle A. Waknitz,Swiergiel Jennifer J,Vivienne S. Marshall,Jeffrey M. Jones +6 more
TL;DR: Human blastocyst-derived, pluripotent cell lines are described that have normal karyotypes, express high levels of telomerase activity, and express cell surface markers that characterize primate embryonic stem cells but do not characterize other early lineages.

The serial cultivation of human diploid cell strains.
Leonard Hayflick,P.S. Moorhead +1 more
TL;DR: A consideration of the cause of the eventual degeneration of these strains leads to the hypothesis that non-cumulative external factors are excluded and that the phenomenon is attributable to intrinsic factors which are expressed as senescence at the cellular level.

Formation of Pluripotent Stem Cells in the Mammalian Embryo Depends on the POU Transcription Factor Oct4
Jennifer Nichols,Branko Zevnik,Konstantinos Anastassiadis,Hitoshi Niwa,Daniela Klewe-Nebenius,Ian Chambers,Hans R. Schöler,Austin Smith +7 more
TL;DR: It is reported that the activity of Oct4 is essential for the identity of the pluripotential founder cell population in the mammalian embryo and also determines paracrine growth factor signaling from stem cells to the trophectoderm.
Journal ArticleDOI
Embryonic stem cell lines from human blastocysts: somatic differentiation in vitro.
TL;DR: The derivation of pluripotent embryonic stem (ES) cells from human blastocysts is described, providing a model to study early human embryology, an investigational tool for discovery of novel growth factors and medicines, and a potential source of cells for use in transplantation therapy.

Differentiation of human embryonic stem cells into embryoid bodies compromising the three embryonic germ layers.
Joseph Itskovitz-Eldor,Maya Schuldiner,Dorit Karsenti,Amir Eden,Ofra Yanuka,Michal Amit,Hermona Soreq,Nissim Benvenisty +7 more
TL;DR: The ability to induce formation of human embryoid bodies that contain cells of neuronal, hematopoietic and cardiac origins will be useful in studying early human embryonic development as well as in transplantation medicine.
