Research progress on the effects of M1/M2 macrophages on the differentiation and maturation of stem cell-derived cardiomyocytes: a review.
Review in Stem cell research & therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Stem cell-derived cardiomyocytes (SC-CMs) represent a promising cell source for cardiac regenerative medicine, disease modeling, and drug screening. However, their clinical translation faces significant challenges, including functional immaturity, poor long-term survival, and inadequate integration with host tissue following transplantation. The immune microenvironment, particularly the dynamic polarization of macrophages into pro-inflammatory (M1) or reparative (M2) phenotypes, is increasingly recognized as a critical regulator of cardiac repair, yet a systematic understanding of its specific effects on SC-CM fate remains incomplete. This review aims to comprehensively evaluate the dual regulatory roles of M1 and M2 macrophages on the differentiation efficiency, structural and functional maturation, and in vivo transplantation efficacy of SC-CMs. A systematic literature search was conducted in PubMed, Web of Science, Nature, and CNKI for relevant studies published from database inception to July 2025. After screening, 92 articles were included for analysis. The synthesized evidence demonstrates that M1 macrophages and their secreted factors (e.g., TNF-α, IL-1β) impede cardiac differentiation by inhibiting the Wnt/β-catenin pathway, disrupt sarcomeric organization and calcium handling, and maintain SC-CMs in a glycolytic, immature state. In contrast, M2 macrophages enhance SC-CM maturation by providing trophic support (e.g., IGF-1, HGF), promoting electrophysiological maturation and metabolic reprogramming towards oxidative phosphorylation, and facilitating angiogenesis via VEGF. The novelty of this review lies in its integrated perspective on macrophage-driven immunomodulation as a central axis for SC-CM maturation. Furthermore, it discusses emerging therapeutic strategies—such as optimized transplantation timing, co-transplantation with immunomodulatory cells, engineered exosomes, and smart biomaterials—that leverage macrophage polarization to create a favorable microenvironment for SC-CMs. Ultimately, harnessing macrophage-SC-CM crosstalk is a crucial step toward advancing clinically effective and immunologically informed cardiac regeneration therapies.
