The research coming under fire reported the discovery of a potentially revolutionary process called stimulus - triggered acquisition of pluripotency (STAP), in which exposing adult cells to a stress such as acid or pressure prompts them to behave like cells in early embryos, which can become any cell type in the body.

Embryonic stem (ES) cells, harvested from three - and - a-half-day-old mouse embryos or five - and - a-half-day-old human embryos, are referred to as pluripotent because they can become any of the thousands of cell types in the body.

Now, researchers at the University of Cambridge have used fluorescent markers to track cell development in the embryo of a cartilaginous fish — a little skate in this case — and found that these thorny scales are in fact created from the same type of cells as teeth: neural crest cells.

Using zebrafish as a model system, the researchers exposed the fish embryos to seven different types of TAML activators.

In the new study, the researchers explored the role of cell shape in two vastly different types of epithelial cells — human bronchial epithelial cells grown in the lab and cells within the living embryo of the fruit fly — and observed them as they matured over time.

Injection of wild - type stage 15 embryos with E. coli constitutively expressing Mcf1 from the high - copy vector pUC18 causes rapid paralysis of embryonic hemocytes and inhibition of phagocytosis as observed following wild - type Photorhabdus infection (Figure 3A and Video S3).

Microinjection of wild - type human ACVR1 RNA into alk8 — / — zebrafish embryos rescued approximately 80 % of the injected embryos completely or partially (Figure 3, C and F), showing that human ACVR1 can function as a BMP type I receptor in this zebrafish model and substitute for Alk8.

Human Embryonic Stem (hES) cells derived from Preimplantation Genetic Diagnosed (PGD)- embryos offer a new alternative source of cellular model as they can be largely expanded, differentiated in several cell types and harbors «naturally» the causative mutation of the pathology.

«Pluripotent» stem cells can become any other type of cell, and they can be derived from embryos or created from adult cells such as skin cells.

Overton studied the elaborate structures on the surfaces of cells in order to understand how single cells established and maintained connections with their partners as they matured to form different types of tissues in the developing embryo.

Genome editing of a human embryo would affect every cell in the embryo's resulting fetus, as opposed to altering the DNA of a select type of cells — such as the stem cells that produce blood cells.

So part of how you make the tissues as an embryo develops is exactly those type of mechanical stresses.

Stem cells are cells found primarily in embryos, and they have not yet taken on the characteristics of any particular type of cell, such as bone, muscle tissue or brain matter.
