1. Embryonic Stem Cells (ESC) – derived from embryo cells (totipotent stem cells) or inner cell mass (pluripotent stem cells), they are able to differentiate into all type of cells of entire body. However, the use of embryonic stem cells for therapeutic purpose arise arise ethical concerns, therefore their application should not be considered in regenerative medicine.
2. Fetal Stem Cells – can be acquired from cord blood, cord tissue and postpartum placenta - their natural reservoir. In standard conditions the the perinatal tissues constitute are discarded according to medical procedures.
3. Somatic Stem Cells– mature cells residing in the adult body and are responsible for tissues regeneration. These are multipotent stem cells (eg. hematopoietic cells) as well as unipotent cells (eg. satellite cells of skeletal muscle). The acquisition of somatic stem cells is well documented and many of them have found application in cellular therapies eg. hematopoietic cell transplantation in the hematological disorders.
