Fully human umbilical cord-derived organoid for acute liver failure

Project description:We report a fully human UC-derived organoid system that integrates ECM hydrogel, MSCs and reprogrammed hepatocytes, achieving the treatment of acute hepatic failure in case of extreme failure.To explore the mechanism of our organoid in hepatic failure, we performed single cell RNA sequencing of transplanted organoids as well as the original organoid prior to transplantation, we have demonstrated that MSCs were primarily responsible for inhibiting the secretion of inflammatory-inducing cytokines and promoting the secretion of inflammation-inhibiting cytokines by recruiting immune cells migrating into organoid to triggering immune response.

Transcriptomic profiling of 27-year cryopreserved umbilical cord blood HSCs/HPCs

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.

cryopreserved CD34 positive human umbilical cord blood cells

Project description:Human umbilical cord blood cells (UCB) is an important alternative resource for the hematopoietic stem cells in treatment of leukemia and other non-malignant diseases. The failure of hematopoiesis reconstruction by the UCB is known to be associated with several clinicopathological features of host patients. There are very few reports available, however, seeking for the association with the quality of umbilical cord blood cells (UCB) themselves. Here we try to address the quality of UCBs by transfusion to the lethally irradiated immunocompromized mice. The cryopreserved CD34+ UCBs cells from twelve different single human donors were transplanted to the irradiated NOD/shi-scid Jic mice. In parallel, total RNAs of the UCBs were subjected to the gene expression profiling with oligonucleotide microarrays. The UCBs from three donors failed to establish the engraftment in the host mice whereas other 9 UCBs succeeded to various extents. Oligonucleotide microarray analysis indicated that 71 genes, including HOXB4 and ETS2, were specifically overexpressed and 23 genes were suppressed more than 2 fold in the successful UCBs comparing with the failed ones (p<0.005, Student’s t-test). Functional annotation analyses revealed that the genes mediated cell growth and cell cycle regulations were enriched in successful UCBs comparing with the failed ones. Our results suggest that the hematopoiesis reconstitution ability may vary among the cryopreserved UCBs and the quality can be distinguished with certain sets of gene expression. The gene expression in human umbilical cord blood cells (UCBs) was measured before transplantation to the lethally irradiated immunocompromized mice. UCBs from 12 individuals were examined.

Maternal-diabetes induced gene expression changes in the umbilical cord

Project description:Analysis of umbilical cord tissue in newborns of type 1 diabetic mothers at gene expression level. The hypothesis tested in the present study was that intrauterine diabetic milieu may effect of fetal umbilical cord gene expression, and via umbilical cord, the alterations may be produced in other fetal tissues as well. Results provide an information of the differentially expressed genes and enriched pathways, such as the dowregulated genes on the pathway on blood vessel development in umbilical cords from diabetic pregnancies. Umbilical cord tissue was collected after elective ceasarean section and was immediately flash frozen in liquid nitrogen and stored at -80C until total RNA extraction from the whole tissue sample. Six cords exposed to maternal diabetes (DM) and six control cords (C) from healthy pregnancies were analyzed.
