Cross-talk between hematopoietic stem cells (HSCs) and the HSC niche is likely important in hematopoiesis but not well demonstrated. Now in Cell Stem Cell, Chen et al. (2019) describe how specialized endothelial cells regulate hematopoietic stem cell maintenance and how hematopoietic stem/progenitor cells facilitate vascular regeneration in return.

骨髓中的互惠主义。

造血干细胞（HSC）与HSC生态位之间的串扰在造血中可能很重要，但尚未得到充分证实。现在在Cell Stem Cell中，Chen等人。（2019）描述了专门的内皮细胞如何调节造血干细胞的维持以及造血干/祖细胞如何促进血管再生。
