Stem-cell differentiation is the process by which a more specialised cell is formed from a stem cell, leading to loss of some of the stem cell's developmental potential. Stem-cell differentiation ...

Mammalian epithelial cells also turn over regularly, typically every few days. Whenever stem cells are called upon to generate a particular type of cell, they undergo an asymmetric cell division.

These are found in an early embryo. These cells are able to divide continuously. Embryonic stem cells are pluripotent. This means that all of the genes in an embryonic stem cell can be expressed ...

A novel tool is used to assess gene function in vitro by targeted endogenous transcriptional activation to unveil novel players in development and disease.

The nucleus of a germline stem cell undergoes two divisions, firstly separating homologous chromosomes and secondly separating chromatids. Haploid gametes contain 23 single chromosomes.
