Abstract
PURPOSE OF REVIEW The cardiovascular and hematopoietic systems share molecular mechanisms and regulatory interactions across species. Endocardial hematopoiesis, a debated topic in mice, is actually an evolutionarily conserved process from Drosophila. This review explores the origins and significance of endocardial hematopoiesis, highlighting its role in cardiac development and macrophage formation. RECENT FINDINGS Despite extensive lineage-tracing and transcriptome studies, it remained unclear until single-cell RNA sequencing (scRNA-seq) identified that endocardial cells possess an intrinsic hematopoietic program independent of known hematopoietic organs. These endocardial-derived macrophages contribute uniquely to cardiac morphogenesis, supporting valve maturation and tissue remodeling. Endocardial hematopoiesis is an evolutionarily conserved phenomenon that is essential for developmental process. The heterogeneity of tissue-resident macrophages and their specialized functions in cardiac development have been further unraveled by single-cell analysis. This review provides an evolutionary perspective on endocardial hematopoiesis and highlights its critical contributions of hematopoietic cells to heart formation and homeostasis.

Abstract
During development, macrophage subpopulations derived from hematopoietic progenitors take up residence in the developing heart. Embryonic macrophages are detectable at the early stages of heart formation in the nascent myocardium, valves and coronary vasculature. The specific subtypes of macrophages present in the developing heart reflect the generation of hematopoietic progenitors in the yolk sac, aorta-gonad-mesonephros, fetal liver, and postnatal bone marrow. Ablation studies have demonstrated specific requirements for embryonic macrophages in valve remodeling, coronary and lymphatic vessel development, specialized conduction system maturation, and myocardial regeneration after neonatal injury. The developmental origins of macrophage lineages change over time, with embryonic lineages having more reparative and remodeling functions in comparison to the bone marrow derived myeloid lineages of adults. Here we review the contributions and functions of cardiac macrophages in the developing heart with potential regenerative and reparative implications for cardiovascular disease.

Abstract
Cardiac resident macrophages play vital roles in heart development, homeostasis, repair, and regeneration. Recent studies documented the hematopoietic potential of cardiac endothelium that supports the generation of cardiac macrophages and peripheral blood cells in mice. However, the conclusion was not strongly supported by previous genetic tracing studies, given the non-specific nature of conventional Cre-loxP tracing tools. Here, we develop an intercellular genetic labeling system that can permanently trace heart-specific endothelial cells based on cell-cell interaction in mice. Results from cell-cell contact-mediated genetic fate mapping demonstrate that cardiac endothelial cells do not exhibit hemogenic potential and do not contribute to cardiac macrophages or other circulating blood cells. This Matters Arising paper is in response to Shigeta et al. (2019), published in Developmental Cell. See also the response by Liu and Nakano (2023), published in this issue.
