Abstract Understanding the repopulating characteristics of human hematopoietic stem/progenitor cell fractions is crucial for predicting their performance after transplant into high-risk patients following high-dose therapy. We report that human umbilical cord blood cells, 78% to 100% of which express the hematopoietic progenitor cell surface marker CD34, can consistently engraft, develop, and proliferate in the hematopoietic tissues of sublethally irradiated NOD/LtSz-scid/scid mice. Engraftment and development of CD34+ cells is not dependent on human growth factor support. CD34+ cells home to the mouse bone marrow (BM) that becomes the primary site of human hematopoietic development containing myeloid, lymphoid, erythroid, and CD34+ progenitor populations. Myeloid, and in particular lymphoid cells possessing more mature cell surface markers, comprise the human component of mouse spleen and peripheral blood, indicating that development proceeds from primary hematopoietic sites to the periphery. Repopulation of secondary recipients with human cells by BM from primary recipients demonstrates the maintenance of substantial proliferation capacity of the input precursor population. These data suggest that the cells capable of initiating human cell engraftment (SCID-repopulating cells) are contained in the CD34+ cell fraction, and that this mouse model will be useful for assaying the developmental potential of other rare human hematopoietic cell fractions in vivo.

It was hypothesized that during mammalian development, the extensive need for hematopoietic cells requires equal contribution to blood cell production from both quiescent and cycling hematopoietic stem cells (HSCs) while maintaining the stem cell pool. To investigate this hypothesis, the engraftment potential of umbilical cord blood (UCB) CD34+ cells residing in either G0(G0CD34+ cells) or G1(G1CD34+ cells) phases of the cell cycle was assessed in nonobese diabetic/severe combined immune-deficient (NOD/SCID) mice. Whereas the level of chimerism in mice transplanted with UCB G0CD34+ cells was 69.9% ± 24.0%, mice receiving equal numbers of G1CD34+ cells harbored 46.7% ± 21.3% human cells 8 weeks posttransplantation. Both groups of cells sustained multilineage differentiation and the production of CD34+cells in recipient animals. The relationship between the number of transplanted G0CD34+ or G1CD34+ cells and the level of chimerism was analyzed by a general linear models procedure. Although the initial level of chimerism following transplantation of G0CD34+ cells was higher than that sustained by G1CD34+ cells, the increment in the degree of chimerism obtained with each additional 103 cells of either phenotype was identical, suggesting that the reconstitution potential of these 2 types of cells was similar. Of interest is that human cells recovered from primary recipients of both G0CD34+ and G1CD34+cells engrafted in secondary NOD/SCID recipients, albeit at a substantially lower level, confirming the primitive nature of UCB CD34+ cells residing in G1.

Abstract Mesenchymal stem cells have been implicated as playing an important role in stem cell engraftment. A new pluripotent population of umbilical cord blood (UCB)-derived Unrestricted Somatic Stem Cells (USSCs), with intrinsic and directable potential to develop into mesodermal, endodermal and ectodermal fates, has recently been identified and characterized (1). In this study we evaluated the capacity of USSCs to influence the homing of UCB -derived CD34+ cells into the marrow and spleen of NOD/SCID mice. Cultured USSCs were co-transplanted with CFDA-labeled cord blood CD34+ cells into sublethally irradiated NOD/SCID mice. Femurs and spleens were harvested 16 hrs thereafter and the percentage of CD34+ cells determined by flow cytometry. USSCs induced a significant enhancement of CD34+ cell homing to both bone marrow and spleen (2.2 ± 0.3 and 2.4 ± 0.6 -fold, respectively; p<0.05). Similar findings were obtained with frozen USSC samples that had been thawed prior to transplantation. The effect of USSCs was specific, as no homing enhancement could be observed by co-transplantation of CD34+ cells with lineage-positive UCB cells, which contain T, B and mature myelo-erythroid cells. Enhanced marrow homing by USSCs was unaltered by extensive culture passaging of the cells, with a similar degree of enhancement observed for both early (p5) and late (p10) passage USSCs (1.7 ± 0.1 and 1.9 ± 0.1 -fold, respectively). Enhanced homing was dose-dependent, detectable at USSC/CD34+ ratios of 1:1 and above. USSCs were also found to enhance the homing of day 14 cells harvested from cultures of selectively amplifiedTM, ex-vivo expanded UCB lineage-negative (lin-) cells. The relative proportion of homing CD34+ cells within the culture-expanded cell population, was unaffected by USSC co-transplantation. Our findings thus demonstrate that USSCs enhance the homing of UCB hematopoietic stem cells and suggest a clinical potential for these cells in facilitating engraftment under conditions of limiting cord blood stem cell numbers.
