Adventitial reticular cells (ARCs) are specialized pericytes of the sinusoids lining the outer surfaces of blood vessels. These bone marrow pericyte-like cells express alpha-smooth muscle actin.
Some studies indicate that adventitial reticular cells (ARCs) best resemble the in vivo correspondents of cultured mesenchymal stem cells (MSCs) from bone marrow (i.e., human bone marrow stromal cells; BMSCs). BMSCs represent a phenotypically homogeneous cell population that shares an identical phenotype with marrow ARCs, which are stromal cells similar in nature to pericytes.
