Transcriptomics signature of human heart vascular pericytes


ABSTRACT: Pericytes (PC) are abundant yet remain the most enigmatic and ill-defined cell population in the heart. Here, we investigated whether PC can be reprogrammed to aid neovascularisation of the heart post-myocardial infarction. We discovered that culture of human cardiac PC for 10 days in the presence of an inhibitor of ERK1/2 signalling (PD0325901, specific MEK1/2 inhibitor) induces the PC switch towards a vascular smooth muscle cells (VSMC)-like phenotype. Differentiated PC became more proangiogenic, more responsive to vasoactive agents, and insensitive to chemoattractants. RNA-Sequencing revealed transcripts marking the PD0325901-induced transition into proangiogenic, stationary VSMC-like cells.
