Stem cell transplantation - new treatment approaches.

Stem cell research still remains one of the most controversial fields of science today on account cell plasticity and its capability of transdifferentiation or de-differentiations to certain tissue types, as well as the clinical application of this scientific concept. Stem cells derived from bone marrow, peripheral blood or the umbilical cords are a common therapeutic approach for treatment of haematological malignancies as part of established transplant procedures (allogeneic, autologous, syngeneic stem cell transplantation).
