• Differentiation


  The development of a stem cell into a specialised cell with a particular function
• Specialised


  Cells which serve a unique, particular function
• Totipotent


  Stem cells which can differentiate into any cell type
• Zygote


  The diploid cell formed by the combination of two haploid gamete cells
• Foetus


  A human embryo after 8 weeks of development
• Pluripotent


  Stem cells that can differentiate into multiple cell types
• Embryonic Stem Cell


  A pluripotent stem cell present during the early stages of human development
• Multipotent


  Stem cells which can differentiate into a limited number of specialised cell types belonging to a specific tissue or organ
• Bone Marrow


  Semi-solid tissue found within bones. Serves as the primary site of the creation of red blood cells and leukocytes
