...As (self-renewing) progenitors of sinusoidal adventitial reticular cells, CD146+ stromal cells contribute to the organization, and become an integral part, of the structure of sinusoidal walls, in the vicinities of which HSCs have been directly localized (Kiel et al., 2005)....

...Considering that many HSCs are associated with sinusoidal endothelium (Kiel et al., 2005), our findings that almost all c-kitSca-1 and CD150CD48(2) CD41(2) cells near the sinusoidal endothelium were in contact with CAR cells surrounding endothelial cells in the extravascular space suggest that HSCs in vascular niches are in contact with CAR cells, raising the possibility that CAR cells are a critical cellular component of vascular niches (Ara et al....
