How would the ability to count adult tissue stem cells accurately impact your research, business, clinical trials, or patient care?

"Stem cell biomarkers," like CD133 and CD34, though useful for enrichment of adult tissue stem cells from several tissues (in particular hematopoietic tissues), lack sufficient specificity for accurate counting of tissue stem cells. In addition to detecting tissue stem cells, these biomarkers also detect non-stem committed progenitor cells, which greatly outnumber tissue stem cells.
