Lee和Ding强调了Hao等人的工作,描述了膜结合干细胞因子与VCAM-1协同作用,诱导调节造血干细胞粘附的极化突起。多能造血干细胞由骨髓小生境维持,但小生境衍生的膜结合干细胞因子(mSCF)如何调节造血干细胞仍不清楚。在这个问题上,Hao et al.(2021. J. Cell Biol. https://doi.org/10.1083/jcb.202010118)描述了mSCF与VCAM-1协同地诱导大的极化突起,所述突起充当HSC到其小生境的锚。
Lee and Ding highlight work from Hao et al. describing that membrane-bound stem cell factor synergizes with VCAM-1 to induce polarized protrusions that regulate adhesion in hematopoietic stem cells. 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.
