​WHAT CAN’T STEM CELLS DO?

HEMATOPOIETIC STEM CELLS PROTECT AGAINST MYELOPROLIFERATIVE NEOPLASIA

After over 15 years of main stream research around the world (with 50 years of bone marrow/stem cell transplant research and therapies), most people still believe there are only a few sources for stem cells; embryonic, adult and induced pluripotent.

Adult stem cells in particular though, consist of a huge number of stem cell sources: embryos, fetuses, placentas, umbilical cord blood, Wharton’s jelly, endometria, peripheral blood, umbilical cord blood, bone marrow, placentas, adipose or fat tissue, skeletal and cardiac muscle, olfactoric mucosal (nasal neurological), breast milk, dental pulp, lungs and many other sources. Chinese scientists have even generated human teeth from the stem cells found in urine.

Each stem cell source appears to have unique qualities and characteristics which scientists are barely beginning to fully understand. The blood or bone marrow have what are called “hematopoietic stem cells.”

“A hematopoietic stem cell is a cell isolated from the blood or bone marrow that can renew itself, can differentiate to a variety of specialized cells, can mobilize out of the bone marrow into circulating blood…” via

As if hematopoietic stem cells weren’t awesome enough due to their ability to produce cells of the blood and the immune system and destroy unneeded cells, they have an additional benefit which may be even more impressive. Hematopoietic stem cells introduced into the patient’s body also protects against myeloproliferative neoplasia.

Myeloproliferative neoplasm is “a type of disease in which the bone marrow makes too many red blood cells, platelets, or certain white blood cells. Myeloproliferative neoplasms usually get worse over time as the number of extra cells build up in the blood and/or bone marrow. This may cause bleeding problems, anemia, infection, fatigue, or other signs and symptoms. Certain myeloproliferative neoplasms may become acute myeloid leukemia (AML). Myeloproliferative neoplasms include chronic myelogenous leukemia (CML), polycythemia vera, primary myelofibrosis, essential thrombocythemia, chronic neutrophilic leukemia, and chronic eosinophilic leukemia. Also called chronic myeloproliferative neoplasm.” via

As research continues, we learn more and more about the abilities of stem cells and their role as one of the most important healing systems in the human body.

HEMATOPOIETIC STEM CELLS

Microenvironment of hematopoietic stem cells can be a target for myeloproliferative disorders

“The protective microenvironment of the hematopoietic stem cell niche, which produces cells of the blood and the immune system, also protects against myeloproliferative neoplasia. Protecting this microenvironment, or niche, has thus emerged as a new route for the treatment of these diseases, for which there is currently no fully effective treatment…”
