Project description:Adipose-derived MSCs (AMSC) are currently utilized in clinical trials for various diseases including osteoarthritis, amyotrophic lateral sclerosis, and multiple system atrophy. Whilst AMSCs may be defined by the surface expression of classical markers including CD44, CD90, CD105, and absence of CD45, these cells may exhbit donor-to-donor differences in differentiation potential. In this study we evaluated the expression of CD36 amongst AMSCs and utilized magnetic cell sorting to enrich for CD36+ cells. Whole transcriptome RNA-sequencing was performed on unsorted, CD36+ enriched, and CD36+ depleted cells to determine gene expression difference between these populations of cells. CD36 sorted or unsorted cells were then plated and maintained in growth medium. Cells were expanded for 2 passages and passage 8 cells were plated for RNA-sequencing analysis. Trizol reagent was used to harvest cells when they were proliferating cells (~80%) or 100% confluent cells.

Project description:We investigated whether the features of donor-derived stromal vascular fraction of perirenal adipose tissue (PRAT-SVF) could be indicative of the deleterious impact of the ECD microenvironment on renal transplants. A comparative analysis of cellular components, transcriptomic and vasculogenic profiles was performed in PRAT-SVF obtained from deceased donors (non ECD) and expanded criteria donors (ECD) The global RNA sequencing approach indicated a differential molecular signature in the PRAT-SVF of ECD donors characterized by the overexpression of inflammatory transcripts (CXCL1, CCL4, IL1-β,INF-ϒ).

Project description:We demonstrated that chemically difined PCL-PVAc-PEG based 3a medium was superior to conventional StemSpan besed medium in expansion of human hematopoietic stem cells. In fact, more phenotypic HSCs (CD34+EPCR+CD90+CD45RA-ITGA3+) were expanded in our culture condition and higher donor chmerism was achieved in transplantation assay using humanized mice. But detail transcriptome profiles of expanded HSCs was unknown and therefore single-cell RNA sequencing was done to reveal it. As a result, expanded cells in our medium had more HSPC featured cells. Interestingly, erythroid/megakaryocyte progenitors was more expanded in our condition. On the other hands, other culture condition made more myeloid progenitor cells but few HSPC featured cells. This result support the idea that our new medium are able to selectively expand HSCs.

Project description:Hematopoietic stem/progenitor cell transplantation (HSCT) is a well-established treatment option for hematological and other disorders. Umbilical cord blood (UCB) is a rich source of hematopoietic stem and progenitor cells (HSPCs). Cluster of Differentiation (CD)34 is commonly used as a cell surface marker to identify and isolate HSPCs. Transplantation using a single UCB unit may be associated with delayed hematopoietic reconstitution as it may not contain a sufficient number of HSPCs required for adult transplantation. One way of overcoming this limitation is through ex vivo expansion of UCB-derived HSPCs using the aryl hydrocarbon receptor (AhR) antagonist, StemRegenin-1 (SR1), which promotes the expansion of HSPCs. Our study investigated the effects of SR1 on the transcriptome of expanded CD34+ cells from UCB, and we also report on a comparison between the transcriptome profiles of 7-day expanded and non-expanded CD34+ cells. CD34+ HSPCs expanded with SR1 for 7 days displayed two significantly downregulated genes, cytochrome P450, family 1, subfamily B, polypeptide 1 (CYP1B1) and erythrocyte membrane protein band 4.1-like 3 (EPB41L3), when compared to controls (without SR1). Transcriptome analysis of CD34+ HSPCs expanded for 7 days using SR1 revealed that 391 genes were significantly upregulated, while 456 genes were significantly downregulated when compared to non-expanded CD34+ cells. In conclusion, though hundreds of genes were differentially expressed between SR1-expanded and non-expanded CD34+ HSPCs, only two genes were significantly downregulated in cells expanded for 7 days with SR1 versus control at the same time point (without SR1).
