Based on the cell type/tissue of origin, stem cells are classified as:

  • Somatic Stem Cells (SSCs) also known as Adult Stem Cells: They have limited capacity of differentiation and may be multipotent or unipotent.
  • Embryonic Stem Cells’ (ESCs) are pluripotent, which mean they can change into any cell in the body.
