在哺乳动物的早期胚胎发育过程中，囊胚的形成涉及外胚层（trophectoderm，TE）的特化，随后内细胞团（inner cell mass，ICM）分化为胚胎上皮细胞 ...

Marker profiling shows that ESCs are distinct from early inner cell mass (ICM) and closely resemble pre-implantation epiblast. A characteristic feature of mouse ESCs is propagation without ERK ...

Embryonic stem (ES) cells, derived from the inner cell mass (ICM) of a blastocyst, can differentiate into almost all kinds of cells of the body under certain circumstances. These so-called ...

This blob is called the inner cell mass. It contains cells with the ability to make all the other types of cells in the human body – i.e. the cells in this blob are pluripotent. Since a whole ...

the single-cell data showed that the key cells that will become the embryo (the inner cell mass or ICM) don't contain jumping genes but instead express a virus-like gene called human endogenous ...

The embryo proper, meanwhile, develops from the blastocyst’s inner cell mass. Dr Sun therefore experimented with the idea of a second and subsequent transplant—moving the inner cell mass of a ...

sometimes called "pluripotential stem cells" (PSCs), are found in the inner cell mass of the preimplantation embryo and in certain cell populations of the early fetus. Stem-cell research took a ...

Through the isolation of inner cell mass from blastocyst stage embryos and culturing them, the researchers succeeded in generating high-quality feline embryonic stem cells. These can be maintained ...

A 5-day-old human embryo, called a blastocyst, contains an inner cell mass composed of about 12 embryonic stem cells. Adult human bodies contain relatively few stem cells, mostly concentrated in ...
