A polarized anchor for hematopoietic stem cells: Synapse between stem cells and their niche?

Multipotent hematopoietic stem cells are maintained by the bone marrow niche, but how niche-derived membrane-bound stem cell factor (mSCF) regulates HSCs remains unclear. In this issue, Hao et al. (2021. J. Cell Biol. https://doi.org/10.1083/jcb.202010118) describe that mSCF, synergistically with VC...

Sumario:Multipotent hematopoietic stem cells are maintained by the bone marrow niche, but how niche-derived membrane-bound stem cell factor (mSCF) regulates HSCs remains unclear. In this issue, Hao et al. (2021. J. Cell Biol. https://doi.org/10.1083/jcb.202010118) describe that mSCF, synergistically with VCAM-1, induces large, polarized protrusions that serve as anchors for HSCs to their niche.
