Neuronal stem cells produce a variety of nervous system tissue, mostly during early embryonic development ... cells" (PSCs), are found in the inner cell mass of the preimplantation embryo and ...

cells different from embryonic stem (ES) cells? What can we use iPS cells for? ES cells were originally derived from the inner cell mass (ICM) or epiblast of mouse embryos. These cells exhibit an ...

“They are not identical,” said Magdalena Zernicka-Goetz, a developmental and stem cell biologist at the California Institute of Technology and the University of Cambridge and study coauthor. “Only one ...

Staining the different cell types in these tumors showed that all the serrated adenomas and 90 percent of the aPKC-deficient conventional adenomas were devoid of ISCs. “We never expected the stem ...

Stem cells are cells that have not yet become specialised for a specific function. This process is called cell differentiation. A small bundle of cells made from embryonic stem cells is called an ...
