More and more doctors are using stem cell therapies to treat people suffering from cancer of blood. Doctors have to face difficulty in collecting enough stem cells from about one in 10 cancer patients to undergo treatment due to one reason or the other.

The new drug, Plerixafor, has solved many problems of doctors by contributing in collection of stem cells. The new drug has led to an improvement in stem cell treatment in cancer patients. The new drug has shown 100% success rate, giving new hope to many cancer patients.

This drug has successfully helped 13 patients in undergoing stem cell treatment. Plerixafor is presently used at the Beatson West of Scotland Cancer Centre in Glasgow but it is not yet licensed.

Blood specialist, Dr Kenneth Douglas explained that the drug works by blocking a chemical scent that stem cells sniff for that tells them they're in the bone marrow.

He said: "If you block that chemical scent they get confused and agitated and they think they are not in the bone marrow any more and they start wandering into the blood stream looking for the bone marrow."

Doctors are able to collect these wandering stem cells in the blood stream which can be later used for treatment.
