Academic Background

BACKGROUND: Umbilical Cord Blood (UCB) stem cells are a non-invasive, effective alternative source of hematopoietic stem cells for the treatment of a variety of diseases. AIM: The aim of the study was to research knowledge, awareness, and attitudes of the general public and health professionals regarding the UCB storage. MATERIALS AND METHODS: A cross-sectional study was conducted with an online survey (n = 408) using the snowball method. RESULTS: A majority of respondents declared that they were not aware of UCB banking; however, people with an academic background in healthcare have a greater awareness of UCB banking. A subjective assessment found that their knowledge of UCB banking is better than that of non-professionals, however, they exhibited better knowledge and understanding of UCB use and banking in only a few aspects. People with an academic background in healthcare have a more polarized attitude toward cord blood banking and a higher percentage are unwilling to pay for UCB banking services. However, their preferences regarding public/private UCB banking do not differ significantly from those of non-professionals. CONCLUSION: Here, we show that there is not much difference between the laic and professional categories in terms of knowledge about the specific purpose and characteristics of UCB storage.

Hematopoietic Stem

Human umbilical cord blood as an alternative source of hematopoietic stem cells for bone marrow reconstitution, has recently been demonstrated to yield successful HLA-matched placental blood grafts in children. It has been shown that cord blood contains sufficient progenitor cells to effect hematological reconstitution. Since then, more than 25 cord blood stem cells (CBSCs) transplants have been performed worldwide for the treatment of a variety of malignant and nonmalignant diseases. The majority of the grafts performed thus far have utilized CBSCs from HLA-identical siblings. However, much of the interest in this setting is devoted to the potential use of CBSCs for HLA-mismatched and unrelated transplants. Preliminary results suggest that allorecognition and graft-versus-host disease may be less intense in CBSCs transplants than in recipients of similarly compatible bone marrow. This review summarizes the results and potential future applications of cord blood transplantation.

Hematopoietic Stem

Abstract Allogeneic hematopoietic stem cell transplantation is a life-saving procedure for hematopoietic malignancies, marrow failure syndromes, and hereditary immunodeficiency disorders. However, wide application of this procedure is limited by availability of suitably HLA-matched adult donors. Umbilical cord blood (UCB) has being increasingly used as an alternative hematopoietic stem cell source for these patients. To date, over 6000 UCB transplant procedures in children and adults have been performed worldwide using UCB donors. Broader use of UCB for adult patients is however limited by the available infused cell dose. This has prompted intensive research on ex vivo expansion of UCB stem cells and UCB graft-engineering including accessory cells able to improve UCB engraftment and reconstitution and for tissue regenerative potential. Recently, two large European and North American retrospective studies demonstrated that UCB is an acceptable alternative source of hematopoietic stem cells for adult recipients who lack HLA-matched adult donors. UCB is anticipated to address needs in both transplantation and regenerative medicine fields. It has advantages of easy procurement, no risk to donors, low risk of transmitting infections, immediate availability and immune tolerance allowing successful transplantation despite HLA disparity.

Hematopoietic Stem

AbstractIt is well accepted that umbilical cord blood has been a source for hematopoietic stem cells. However, controversy exists as to whether cord blood can serve as a source of mesenchymal stem cells, which can differentiate into cells of different connective tissue lineages such as bone, cartilage, and fat, and little success has been reported in the literature about the isolation of such cells from cord blood. Here we report a novel method to obtain single cell-derived, clonally expanded mesenchymal stem cells that are of multilineage differentiation potential by negative immunoselection and limiting dilution. The immunophenotype of these clonally expanded cells is consistent with that reported for bone marrow mesenchymal stem cells. Under appropriate induction conditions, these cells can differentiate into bone, cartilage, and fat. Surprisingly, these cells were also able to differentiate into neuroglial- and hepatocyte-like cells under appropriate induction conditions and, thus, these cells may be more than mesenchymal stem cells as evidenced by their ability to differentiate into cell types of all 3 germ layers. In conclusion, umbilical cord blood does contain mesenchymal stem cells and should not be regarded as medical waste. It can serve as an alternative source of mesenchymal stem cells to bone marrow.

Cd34 Cells

Abstract A novel Hoechst 33342 dye efflux assay was recently developed that identifies a population of hematopoietic cells termed side population (SP) cells. In the bone marrow of multiple species, including mice and primates, the SP is composed primarily of CD34−cells, yet has many of the functional properties of hematopoietic stem cells (HSCs). This report characterizes SP cells from human umbilical cord blood (UCB). The SP in unfractionated UCB was enriched for CD34+ cells but also contained a large population of CD34− cells, many of which were mature lymphocytes. SP cells isolated from UCB that had been depleted of lineage-committed cells (Lin− UCB) contained CD34+ and CD34− cells in approximately equivalent proportions. Similar to previous descriptions of human HSCs, the CD34+Lin− SP cells were CD38dimHLA-DRdimThy-1dimCD45RA−CD71−and were enriched for myelo-erythroid precursors. In contrast, the CD34−Lin− SP cells were CD38−HLA-DR−Thy-1−CD71−and failed to generate myelo-erythroid progeny in vitro. The majority of these cells were CD7+CD11b+CD45RA+, as might be expected of early lymphoid cells, but did not express other lymphoid markers. The CD7+CD34−Lin− UCB SP cells did not proliferate in simple suspension cultures but did differentiate into natural killer cells when cultured on stroma with various cytokines. In conclusion, the human Lin− UCB SP contains both CD34+ multipotential stem cells and a novel CD7+CD34−Lin− lymphoid progenitor. This observation adds to the growing body of evidence that CD34− progenitors exist in humans.
