what is the importance of stemcells in regeneration?
 There are two main types of stem cell: (1) embryonic stem cells (ES cells), sometimes referred to as plain ‘stem cells’ and, (2) adult stem cells, sometimes referred to as somatic stem cells.

    There are two main driving forces behind stem cell biology as applied to humans.

    The first is the desire to be able to replace damaged or diseased tissue/organs without recourse to organ donation. (There are not enough suitable organs from donations to satisfy the demand, and all transplants carry some risk of rejection. Organ recipients may also be affected by taking the required immunosuppressive drugs).

    The second driving force is the need to be able to culture specific human stem cells to (1) study normal and disease development at the level of the cell, and (2) use stem cells for medicinal drug discovery and testing.
