Evolution of cancer stem cells

Scientists edge nearer unlimited blood bank

French scientists have managed to generate red blood cells from stem cells and inject them back in to the donor. This major achievement opens up the possibility of a stem cell-based alternative to donated blood cells.

Human Development and Stem Cells

Human embryonic development depends on stem cells. During the course of development, cells divide, migrate, and specialize. Early in development, a group of cells called the inner cell mass (ICM) forms. These cells are able to produce all the tissues of the body. Later in development, during gastrulation, the three germ layers form, and most cells become more restricted in the types of cells that they can produce.
