Project description:This includes bulk RNA-seq samples for sorted LT-HSCs, ST-HSCs, and MPPs stimulated (or not) with LPS+PAM. Samples taken at various time points.
Project description:This includes single cell RNA-seq samples for sorted LT-HSCs, ST-HSCs, and MPPs stimulated (or not) with LPS+PAM. Samples taken at 2 hours post stimulation (if applicable).
Project description:Small nucleolar RNA (snoRNA) are non-coding RNAs, which participate in the chemical modification of ribosomal RNAs (rRNAs) and small nuclear RNAs. However, the roles of snoRNA in homeostasis of hematopoietic stem cells(HSCs) have not been studied. We isolated four hematopoietic stem and progenitor cells (HSPCs) (LT-HSCs, IT-HSCs, ST-HSCs, and MPPs) from the bone marrow (BM) of C57BL/6 mice and performed small RNA-seq. We found SnoRNAs belonging to SNORD113-114 cluster were specifically enriched in LT-HSCs, and their expression decreased dramatically with HSC differentiation. Here, we used a modified small RNA-seq method to examine snoRNA profiles of hematopoietic progenitor and mature cells in WT mice.

To explore function of snoRNAs in SNORD113-114 cluster in HSCs, we established maternally KO mice by CRISPR-Cas9 technology. Here, we used a modified small RNA-seq method to examine snoRNA profile in KO mice.
Project description:We isolated murine fetal liver and murine adult bone marrow and FACS sorted LT-HSCs, ST-HSCs and MPPs. We used global expression analysis by microarray to compare regulated genesets in different HSC populations in fetal and adult.
