Project description:This SuperSeries is composed of the following subset Series: GSE40829: Expression profiles of lineage-depleted (Lin-) cell and mono-nucleated cell (MNC) samples derived from human umbilical cord blood GSE40830: Expression analysis of uncultured and culture-derived colony forming unit-monocytes and megakaryocytes Refer to individual Series
Project description:Umbilical cord blood banking is critical for the success of umbilical cord blood transplants. Here we analyzed transcriptomic differences between 27-year cryopreserved umbilical cord blood hematopoietic stem cells (HSCs) and multipotent progenitor cells (MPPs) and those derived from fresh cord blood. We also leveraged differences in engraftment capacity to examine the transcriptomes of HSCs/HPCs defined by engraftment capacity, demonstrating the feasibility of this approach for identifying potency markers to aid in the selection of cord blood units for transplantation and revealing novel potential regulators of cord blood HSC/HPC engraftment.
Project description:Stem/progenitor cells demonstrate neuro-regenerative potential that is dependent upon their humoral activity by producing various trophic factors that regulate cell migration, growth, and differentiation. To better characterise the human umbilical cord blood-derived stem/progenitor cells, we analyzed the global gene expression pattern in the lineage-negative, CD34+, CD133+ cells and unseparated nucleated cells. We were interested in biological processes concerning biosynthetic processes, cytokine production, secretion by cells, chemotaxis, migration, and proliferative capacities.
