Stem cells are immature cells that can develop into any cell present in the bloodstream: red blood cells, white blood cells, platelets and other blood components. Blood stem cells are not embryonic stem cells. They come from bone marrow, circulating (peripheral) blood or umbilical cord blood. People whose diseases inhibit their ability to produce these kinds of cells need a transplant of healthy stem cells from a donor. Donors may be asked to donate either.

HSCs are found in the bone marrow of adults, specially in the pelvis, femur, and sternum. They are also found in umbilical cord blood and, in small numbers, in peripheral blood. Stem and progenitor cells can be taken from the pelvis, at the iliac crest, using a needle and syringe.

In order to harvest stem cells from the circulating peripheral blood, blood donors are injected with a cytokine, such as granulocyte-colony stimulating factor (G-CSF), that induces cells to leave the bone marrow and circulate in the blood vessels.

Hematopoietic stem cells (HSCs) are the blood cells that give rise to all the other blood cells and are derived from mesoderm. They are located in the red bone marrow, which is contained in the core of most bones. They give rise to both the myeloid and lymphoid lineages of blood cells.

Ultimately, the technique could be used to produce tissue for an autologous lung graft. The lung cells would be removed from an organ donor's lung, leaving only a scaffold behind, which could be seeded with freshly made lung cells from the patient, the researchers said.

1 Bone marrow is the soft, jelly-like tissue found in the hollow centre of bones. 2  It is like a factory that produces stem cells, which are the building blocks of blood. 3  Bone marrow donors undergo a surgical procedure where the marrow containing the stem cells is collected from the pelvic bones.

Scientists had previously converted stem cells into cells of the heart, intestine, liver, nerves and pancreas. Now, we are finally able to make lung and airway cells, study leader Dr. Hans-Willem Snoeck, a professor of microbiology and immunology at Columbia University in New York, said in a statement.

HSCs have a higher potential than other immature blood cells to pass the bone marrow barrier, and, thus, may travel in the blood from the bone marrow in one bone to another bone. If they settle in the thymus, they may develop into T cells.

Patients who receive lung transplants today have a poor prognosis. But future approaches involving transplants that use the patient's own stem cells to generate lung tissue could reduce the chances that a patient's immune system would reject the transplant, the researchers said.
