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

Genomic instability in pluripotent stem cells: implications for clinical applications.
TL;DR: To minimize any effects of acquired mutations on cell therapy, it is strongly recommend that cells destined for transplant be monitored throughout their preparation using a high-resolution method such as SNP genotyping.

Porcine embryonic stem cells: Facts, challenges and hopes
TL;DR: Data from the literature will be presented together with experimental evidence recently obtained in the laboratory and aspects related to the timing of isolation, the initiation of primary cultures, the use of different culture conditions and cytokines, the identification of pluripotency-related molecular markers in the pig will be examined.

Microvascular development: learning from pancreatic islets
TL;DR: The special morphology of islet capillaries and its role in the physiologic function of islets: secretion of insulin in response to blood glucose levels, and its critical role during type I diabetes and islet transplantation are described.

WWP2 promotes degradation of transcription factor OCT4 in human embryonic stem cells
TL;DR: It is reported that human WWP2, an E3 ubiquitin (Ub)-protein ligase, interacts with OCT4 specifically through its WW domain and enhances Ub modification of OCT4 both in vitro and in vivo and demonstrates that WWP 2 is an important regulator of the OCT4 protein level in human ES cells.

History and perspective of stem cell research
Ariff Bongso,Mark Richards +1 more
TL;DR: Stem cell research opens-up the new field of 'cell-based therapies' and, as such, several safety measures have also to be evaluated.

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.

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.

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.
