- - - - somatik---->somatik(farkllı)

    - - bir yönde farklılaşması gereken bir kök hücrenin farklı bir yönde farklılaşması
    - - bir kök hücre grubunun planlanmış hücre tipine dönüşmek yerine başka bir germ hücresine dönüşmesi
- - - - Adult stem cells supply new cells as an organism grows and to replace cells that get damaged.
      - Adult stem cells are said to be multipotent, which means they can only change into some cells in the body, not any cell, for example:
        
        Skin (or 'epithelial') stem cells provide the different types of cells that make up our skin and hair.
        
        Blood (or 'haematopoietic') stem cells can only replace the various types of cells in the blood.
    - - ‘Induced’ means that they are made in the lab by taking normal adult cells, like skin or blood cells, and reprogramming them to become stem cells.
      - Just like embryonic stem cells, they are pluripotent so they can develop into any cell type.
      - Induced pluripotent stem cells, or ‘iPS cells’, are stem cells that scientists make in the laboratory.
    - - These stem cells are said to be pluripotent, which means they can change into any cell in the body
      - Embryonic stem cells supply new cells for an embryo? as it grows and develops into a baby.
