Project description:The BM-derived CD45+/Sca1+ cells are haematopoietic stem/progenitor cells that have the ability to circulate and migrate and engraft to the muscle tissue, and therefore they are of particular interest. Notably, these cells retain their haematopoietic potential, as revealed both by in vitro and in vivo assays; but they also acquire myogenic potential, as shown by their ability to participate in muscle regeneration. Whether, this latter remarkable ability is the result of the reprogramming of the BM-CD45+/Sca1+ cells and the activation of a myogenic molecular program within these cells, remains controversial. This study aims to clarify this aspect of the process, investigating the role of the muscle microenviroment and key myogenic transcription factors. Keywords: CD45+/Sca1+ cells, BM, muscle CD45+/Sca1+ cells isolated from the BM or the muscle were processed fresh and their RNA was extracted. Moreover, CD45+/Sca1+ cells isolated from the muscle of BM transplanted or untransplanted mice after injury with Cardiotoxin were processed fresh and their RNA was extracted.

Project description:RNA and ATAC sequencing data of primary sorting CD45-Ter119-CD31-Scf; GFP+Cxcl12; DsRed+ bone marrow stromal cells ,2D cultured bone marrow stromal cells and 3D cultured bone marrow stromal cells. RNA sequencing data of sorted primary and 3D cocultured Lin-Sca1+C-kit+CD150+CD48+ hematopoietic stem cells from 8-12 weeks and 12-13 months old mice. RNA and ATAC sequencing data of primary sorting CD45-Ter119-CD31-Pdgfra+td-Tomato+ bone marrow stromal cells from young (8 wks), middle aged (12 months) and aged (22-24 months) Lepr-Cre;td-Tomato mice.
Project description:The purpose of the study is to compare the protein changes between cirrhosis control and therapy groups for bone marrow-sorted LSK cells.
Project description:Analyze and compare the gene expression profile of human bone marrow primary CD45-CD271+ and CD45-CD271- cells. The hypothesis was some genes were differentially expressed in these two populations. Results provided important information regarding the gene expression difference of these two cell populations.
