CD34 defines an osteoprogenitor cell population in mouse bone marrow stromal cells
Bone marrow stromal cells (BMSCs, also known as bone marrow-derived mesenchymal stem cells) and their progenitors have been identified based on retrospective functional criteria. CD markers are employed to define cell populations with distinct functional characteristics. However, defining and prospe...

Bone marrow stromal cells (BMSCs, also known as bone marrow-derived mesenchymal stem cells) and their progenitors have been identified based on retrospective functional criteria. CD markers are employed to define cell populations with distinct functional characteristics. However, defining and prospective isolation of BMSCs and committed progenitors are lacking. Here, we compared the transcriptome profile of CD markers expressed at baseline and during the course of osteoblast and adipocyte differentiation of two well-characterized osteogenic-committed murine BMSCs (mBMSCBone) and adipogenic-committed mBMSCs (mBMSCAdipo), respectively. Bioinformatic analysis revealed the presence of a core set of canonical mBMSC CD markers with comparable expression levels in mBMSCBone and mBMSCAdipo at baseline and during their differentiation. We identified 11 CD markers that are differentially expressed between mBMSCAdipo and mBMSCBone.
