Within multicellular organisms, tissues are organized communities of cells that work together to carry out a specific function. The exact role of a tissue in an organism depends on what types of ...

When cells express specific genes that characterise a certain type of cell we say that a cell has become differentiated. Once a cell becomes differentiated it only expresses the genes that produce ...

Understanding how cells transform into specialized types during human development is a central challenge in biology. This ...

Scientists hypothesize that the ancestor of regA, "proto-regA," acted in a stress-activated pathway (shaded gray) that led to the repression of growth and cell division. Duplication of proto-regA ...

Research from Umeå University paves the way for a quantitative data analysis method to study the cell division process in ...

A "pocket" on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Two studies by researchers at the University of Konstanz investigated ...

and persist throughout life through a cell division mechanism called self-renewal. Differentiation and self-renewal often go awry in blood cancer, or leukemia, to enable unlimited proliferation of ...

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 ...
