Abstract: Pericytes, also known as mural cells, are cells embedded between endothelial cells and the
basement membrane of capillaries, where they orchestrate the morphological and functional homeostasis
of blood vessels. Within the tumor microenvironment, pericytes interact closely with various
cellular components, including tumor cells, stromal cells, and immune cells. Through these dynamic
interactions, pericytes are activated and subsequently transform into tumor-associated pericytes
(TPCs). The origin of TPCs varies depending on the tissue and tumor type, contributing to their phenotypic
and functional heterogeneity. TPCs play pivotal roles in facilitating tumor progression, metastasis,
immune evasion, and therapeutic resistance by promoting angiogenesis, engaging in reciprocal
interactions with tumor cells, remodeling the extracellular matrix, and fostering an immunosuppressive
microenvironment. This review synthesizes the latest significant advancements in targeted
therapies against TPCs. It underscores the challenges inherent in developing effective anti-TPC therapies,
which include the heterogeneity and pluripotency of TPCs, the absence of specific markers for
precise TPC targeting, and the limited understanding of how current anti-tumor therapies affect TPCs
and vice versa. This review furnishes a comprehensive understanding of the origins, markers, and
functions of TPCs, and their interplays within the tumor microenvironment, providing prospective
strategies for more effective anti-tumor therapy.
