Blood Stem Cell Breakthrough?

Blood Stem Cell Breakthrough?

Genetic Engineering News published a press release from the biotech company Pluristem, saying that it has developed a new method of separating stem cells from the tissue they are contained in. The press release says (and this is over my head technically):

Pluristem's advanced approach to cell selection and separation was accomplished by using non-selected mononuclear cells (MNC) in the Company's U.S. patented three dimensional scaffolding with flow-through co-culture techniques simulating the physiological environment within the bone marrow. The efficacy of the system in expanding non-selected MNC is based upon the selective adherence of HSC and early progenitor cells from the general MNC pool to the 3-D stroma cells cultures within the bioreactor system.

Since this is a press release from a company, it is full of optimistic language about increasing the availability of the stem cells, which would certainly be a good thing. Anyone out there able to comment on this technique and its viability for widespread use?
