Within few years, the possibility that the human body contains cells that can repair and regenerate damaged and diseased tissue has gone from an unlikely proposition to a virtual certainty.

Patients who have received doses of radiation in the potentially low to mid-lethal range (2-6 Gy) will have depression in bone-marrow function with cessation of blood-cell production leading to pancytopenia.

Selection of cases for stem cell transplantation is based upon clinical signs and symptoms.

Hematopoietic stem cell which produces blood cell progeny provides support for hematopoietic and other cells within the marrow, and has also been a focus for possible tissue repair.

Another cell type termed mesenchymal or stromal also exists in the marrow.

This cell provides support for hematopoietic and other cells within the marrow, and has also been a focus for possible tissue repair.

Stem cells are obtained from bone marrow, peripheral blood, placental and umbilical cord blood, embryonic stem cells and embryonic germ cells.

These cells have great potential for clinical research due to their potential to regenerate tissue.

As is well known, the cryopreservation process can store any cell type, particularly blood cells, for an indeterminate time.
