Bush's decision in August 2001 to permit federal financing for research on human embryonic stem (ES) cells using established ES cell lines. Stem-cell research has enormous potential value in both ...

In 2005, the National Academies released the book, Guidelines for Human Embryonic Stem Cell Research ... including the criteria for determining which stem cell lines it is acceptable to use. Future ...

However, to create ES cell lines, it is necessary to destroy preimplantation ... research on ES cells derived from the destruction of human blastocysts is morally unacceptable.

Human embryonic stem cells accrue changes in their genomes that could make them unusable therapeutically when cultured at length, an international team of scientists report in the October Nature ...

The plating density of MEFs required will vary from human embryonic stem cell line to cell line. We use between 2 × 10 5 and 4 × 10 5 cells per p60 plate, depending on the cell line under study.

This team used a different approach, adding recombinase sites to transposons—mobile genetic elements—that randomly integrated in the genomes of human cell lines and mouse embryonic stem cells.

In the beginning, one cell becomes two, and two become four. Being fruitful, they multiply into a ball of many cells, a shimmering sphere of human potential. Scientists have long dreamed of ...

The generation of the cell line was reported today in the online edition of the journal Reproductive Biology. Dr Minger said: "We are very excited about this development. Human embryonic stem ...

but they also contain a mechanism for approving individual cell lines that don't meet the letter of the law but still adhere to the spirit of informed consent. Human embryonic stem cellsImage: ...
