Stem cells

Stem cells are a peculiar group of cells whose cell fate is not yet determined. These are considered totipotent cells for their ability to originate any kind of cell by a process called cellular differentiation. Early in development, cells of the morula are totipotent and, with the evolution of the embryo, they will differentiate into specialized cells that will result in the formation of all the different organs. However, there is a small amount of bone marrow stem cells in an adult individual destined to the production of other marrow cells and erythrocytes.
