A single-cell RNA-sequencing time course of liver colonisation by colorectal cancer metastases
Ontology highlight
ABSTRACT: Murine colorectal cancer cells were injected into the portal vein of NOD.Cg-PrkdcSCID Il2rgtm1Wjl/SzJ mice. Liver metastatic cells were harvested at specific time points for single-cell RNA-sequencing (SORT-seq).
Project description:We engrafted empty vector, wild type CCL22, and Pro79Arg-CCL22 mutant-expressing NK-92 cells into NOD.Cg-Prkdcscid Il2rgtm1Wjl Tg(IL15)1Sz/SzJ mice to assess in vivo function of detected CCL22 mutations. Engrafted Pro79Arg NK-92 cells recapitulated the phenotype of CLPD-NK patients with CCL22 mutations.
Project description:Human salispheres, a culture of stem/progenitor cells, represent a potential therapy for radiation induced hyposalivation. Radiation-induced hyposalivation dramatically reduces quality of life of patients. We have demonstrated the potential of human salispheres to engraft and differentiate when transplanted into a mouse model of hyposalivation, in the manuscript associated with these data. We also demonstrate the functional recovery of irradiated salivary glands (SGs) following human salisphere transplantation, by the measurement of saliva production. We previously employed Illumina microarrays to determine if transplanted human salisphere cells exert a paracrine stimulatory effect on recipient mouse SGs. Results of this array unveiled a large cohort of immuneresponse genes unregulated following human salisphere transplantation. In order to negate this immune response and unveil any true paracrein stimulatory effects, we performed autologous transplantation of salispheres from NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG) mice, the same model employed in our first microarray study, in the irradiated SGs of NSG mice. 6 samples were analysed in total. Total RNA from 3 irradiated control SGs (5Gy irradiation) and 3 salivary glands transplanted with 100,000 NSG salispheres.

Project description:Osteolineage cells represent one of the critical bone marrow niche components that support maintenance of hematopoietic stem and progenitor cells (HSPCs). Recent studies demonstrate that extracellular vesicles (EVs) regulate stem cell development via horizontal transfer of bioactive cargo, including microRNAs (miRNAs). Here, we characterize the miRNA profile of EVs secreted by human osteoblasts and study their biological effect of on human umbilical cord blood-derived CD34+ HSPCs by sequencing, gene expression and biochemical analyses. Using next-generation sequencing we show that osteoblast-derived EVs contain highly abundant miRNAs specifically enriched in EVs, including critical regulators of hematopoietic proliferation (e.g., miR-29a). EV treatment of CD34+ HSPCs alters the expression of candidate miRNA targets, such as HBP1, BCL2 and PTEN. Furthermore, EVs enhance proliferation of CD34+ cells and their immature subsets in growth factor-driven ex vivo expansion cultures. Importantly, EV-expanded cells retain their differentiation capacity in vitro and show successful engraftment in NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG) mice in vivo. These discoveries reveal a novel osteoblast-derived EV-mediated mechanism for regulation of HSPC proliferation and warrant consideration of EV-miRNAs for the development of expansion strategies to treat hematological disorders.

We also demonstrate the functional recovery of irradiated salivary glands (SGs) following human salisphere transplantation, by the measurement of saliva production. When analyzing human salisphere- transplanted SGs for the presence of human cells, we noted that the highest proportion of human cells were present 1 week after transplantation. This microarray study was designed to determine if paracrine signaling from transplanted human salisphere cells to recipient mouse SGs accounts for a part of the functional recovery of the recipient SG we observe. We compare the transcriptome from irradiated control SG of immunecompromised NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG) mice with that of NSG SGs transplanted with 100,000 human salisphere cells. All mice were sacrificed 1 week following transplantation (or non-transplantation in case of controls) and Illumina array chips used to detect differences in gene expression. 6 samples were analysed in total. Total RNA from 3 irradiated control SGs (5Gy irradiation) and 3 salivary glands transplanted with 100,000 human salispheres.

Project description:The PMCC AML RNAseq dataset consists of 81 AML patient samples (clinical data in Supplemental Table 11), processed in two batches. These patient samples are able to engraft in the NSG (NOD.Cg PrkdcscidIl2rgtm1Wjl /SzJ) mouse model. Five patients (90543, 598, 90240, 110484, 100500) were included in both batches.
