Embryonic stem cell

Embryonic stem cells
Main article: Embryonic stem cell
Embryonic stem cell lines (ES cell lines) are cultures of cells derived from the epiblast tissue of the inner cell mass (ICM) of a blastocyst or earlier morula stage embryos [6].

Embryonic stem cell A cell found in early embryos that can renew itself and differentiate into the many cell types that are found in the human body.

Embryonic stem cell ethical debate
Blastocysts
A blastocyst is a stage of development of an embryo when it is around five days old and made up of about 100 cells.

The Embryonic Stem Cell Method (Method "1")
Embryonic stem cells (ES cells) are harvested from the inner cell mass (ICM) of mouse blastocysts.

Embryonic stem cells have the other advantage that they are multipotent and can turn into many different types of tissue in culture and therefore it's possible to learn from studying embryonic stem cells how differentiation occurs.

There are also embryonic stem cells, and these are derived from three and a half days in the mouse and about six- to eight-day embryos in people, and these are cells with even more potential than the adult cells, ...

This laborious method involves transfecting a crippled gene into cultured embryonic stem cells, searching through the thousands of resulting clones for one in which the crippled gene exactly replaced the normal one (by homologous recombination), ...

A mouse BAC library, made from the 129 mouse-strain embryonic stem cells used for producing transgenic mice, contains 230,000 clones (average insert size, 140 kb) and can be obtained from Research Genetics.
