From one cell to many cell types

From one cell to many cell types

A stem cell surrounded by examples of specialised cells, including nerve, muscle, blood, epithelial, fat, bone, immune and gamete cells

A specialised cell has structures that adapt it to carry out a particular function. Most nucleated somatic cells in a multicellular organism contain the same set of genes because they developed from the same fertilised egg. Gametes are an exception: they are haploid and contain different combinations of alleles following meiosis. Mature human red blood cells are also an exception because they have no nucleus and therefore contain no nuclear genes.
