(Very) Small Stem-like Cells in Human Cell Cultures.

Very Small Embryonic-like Stem Cells (VSELSCs) and Very Small Cancer Stem Cells (VSCSCs) are fields of intensive research. Although the presence in vitro of VSELSC and VSCSC cellular stage analogs appear probable, it has yet to be published. Utilizing established human cell cultures with varying populations of primitive cells, stained with CD markers specific to primitive stages, in addition to a fluorescent DNA dye, and following histochemical processing, we have developed a cytological method for detecting Very Small Leukemic Stem-like Cells (VSLSLCs), Very Small Cancer Stem-like Cells (VSCSLCs), and VSELSCs. This detection provides an opportunity to advance research in these areas.
