Human hematopoietic stem cells (hsc) as stated above, all mature blood cell lineages are derived from distinct progenitor cells that arise from self-renewing hematopoietic stem cells (hscs) there is a lot of information about the murine (mouse or rat) hsc system but the biology of the human hsc remains poorly understood.

Main applications of stem cell therapy are reviewed, from the established use of haemopoietic stem cells for clinical transplantation in a variety of haematological disorders to the initial attempts to employ stem cells for the treatment of other disparate conditions.
A range of assays have been developed to determine the stemness or stem cell activity of human stem cells the key assays of stem cells are functional: they must show self-renewal and the ability to generate the appropriate tissue the best assays available to study this property in putative human stem cells involve xeno-transplantation into immune-deficient mice.

In vitro assays for hematopoietic stem and progenitor cells culture assays can be used to examine the ability of hematopoietic stem and progenitor cells to proliferate and differentiate in response to hematopoietic growth factors and to study their interactions with stromal cells of the hematopoietic microenvironment. In addition to its essential role in the development, nutrition and immunological tolerance of the product of conception, human placenta is an important source of stem cells. Pluscellect™ human cd34+ hematopoietic stem cells isolation kit catalog number pls7227 for the isolation or depletion of human cd34 expressing cells this kit contains sufficient reagents for 25 tests (up to 1 x 109 total cells) this package insert must be read in its entirety before using this product.
Hematopoietic stem cells (hscs) are defined by their ability to repopulate all of the hematopoietic lineages in vivo and sustain the production of these cells for the life span of the individual in the absence of reliable direct markers for hscs, their identification and enumeration depends on functional long-term, multilineage, in vivo repopulation assays.

Isolation of mesenchymal stem cells from murine bone marrow are referred to as hematopoietic stem cells (hsc) and mesenchymal stem cells (msc) friedenstein referred to this single cell as an osteogenic stem cell or a bm stromal stem cell.
Since 1988 a huge progress was made in purification and isolation of hematopoietic stem cells in mice and human but weissman group paved the way for facs application in cell purification and set a new advanced level of stem cell research. Reported in 1989, studies by broxmeyer, gluckman, and colleagues demonstrated that umbilical cord blood (ucb) is a rich source of hematopoietic stem/progenitor cells (hspc) and that ucb could be used in clinical settings for hematopoietic cell transplantation since then, a great interest has been generated on the biological characterization of these cells.
