Abstract

The contractile ability of the mammalian heart critically relies on blood coronary circulation, essential to provide oxygen and nutrients to myocardial cells. In addition, the lymphatic vasculature is essential for the myocardial immune response, extracellular fluid homeostasis and response to injury. Recent studies identified different origins of coronary lymphatic endothelial cells, however, the cues that govern coronary lymphangiogenesis remain unknown. Here we show that the coronary lymphatic vasculature develops in intimate contact with the epicardium and with epicardial-derived cells. The epicardium expresses the lymphangiogenic cytokine VEGFC and its conditional deletion in the epicardium abrogates coronary lymphatic vasculature development. Interestingly, VEGFD is also expressed in the epicardium and cooperates with VEGFC in coronary lymphangiogenesis, but it does so only in females, uncovering an unsuspected sex-specific role for this cytokine. These results identify the epicardium/subepicardium as a signaling niche required for coronary lymphangiogenesis and VEGFC/D as essential mediators of this role.

期刊介绍： EMBO Reports is a scientific journal that specializes in publishing research articles in the fields of molecular biology, cell biology, and developmental biology. The journal is known for its commitment to publishing high-quality, impactful research that provides novel physiological and functional insights. These insights are expected to be supported by robust evidence, with independent lines of inquiry validating the findings. The journal's scope includes both long and short-format papers, catering to different types of research contributions. It values studies that: Communicate major findings: Articles that report significant discoveries or advancements in the understanding of biological processes at the molecular, cellular, and developmental levels. Confirm important findings: Research that validates or supports existing knowledge in the field, reinforcing the reliability of previous studies. Refute prominent claims: Studies that challenge or disprove widely accepted ideas or hypotheses in the biosciences, contributing to the correction and evolution of scientific understanding. Present null data: Papers that report negative results or findings that do not support a particular hypothesis, which are crucial for the scientific process as they help to refine or redirect research efforts. EMBO Reports is dedicated to maintaining high standards of scientific rigor and integrity, ensuring that the research it publishes contributes meaningfully to the advancement of knowledge in the life sciences. By covering a broad spectrum of topics and encouraging the publication of both positive and negative results, the journal plays a vital role in promoting a comprehensive and balanced view of scientific inquiry.
