Human embryonic stem cell lines generated without embryo destruction.
Already in 2006 the group of Irina Klimanskaya / Robert Lanza had published a controversially discussed paper on the generation of human embryonic stem cells (hESCs) from cells that had been obtained by blastomere biopsy. Title and abstract of that paper suggested that removal of one or only few cells from an embryo could be sufficient, and that the original embryo might survive undamaged, so t...
متن کاملDerivation of human embryonic stem cell lines.
Human embryonic stem cells (hESC) are undifferentiated cells derived from an early embryo that can grow in vitro indefinitely, while retaining their capability to differentiate into specialized somatic cell types. Over the last decade there has been great interest in derivation and culture of these cells, as they can potentially provide a supply of readily available differentiated cells and tis...
متن کاملDifferences between human embryonic stem cell lines.
The promise of human embryonic stem cell (hESC) lines for treating injuries and degenerative diseases, for understanding early human development, for disease modelling and for drug discovery, has brought much excitement to scientific communities as well as to the public. Although all of the lines derived worldwide share the expression of characteristic pluripotency markers, many differences are...
متن کاملHuman embryonic stem cell (hESC) and human embryo research.
Human embryonic stem cell research has emerged as an important platform for the understanding and treatment of pediatric diseases. From its inception, however, it has raised ethical concerns based not on the use of stem cells themselves but on objections to the source of the cells--specifically, the destruction of preimplantation human embryos. Despite differences in public opinion on this issu...
متن کاملNo Relationship between Embryo Morphology and Successful Derivation of Human Embryonic Stem Cell Lines
BACKGROUND The large number (30) of permanent human embryonic stem cell (hESC) lines and additional 29 which did not continue growing, in our laboratory at Karolinska Institutet have given us a possibility to analyse the relationship between embryo morphology and the success of derivation of hESC lines. The derivation method has been improved during the period 2002-2009, towards fewer xeno-comp...
