Summary: Deciphering the clues of a regenerative mechanism for the mammalian adult heart, particularly focusing on the role of DAND5, could potentially lead to the development of more effective treatment options for heart failure. Further research on the transcriptional profiling sequencing and quantitative RT-PCR assays of DAND5 may provide insights into the generation and expansion of pluripotent stem cell-derived cardiomyocytes systems for clinical applications.

Summary: Studies have shown that cardiac mesenchymal cells (MCs) contribute to the formation of cardiac adipocytes (CAs), with PDGFRb(+) MCs identified as the major source. PDGFRb(+) cells are heterogeneous, and PDGFRa(+)PDGFRb(+) double-positive periendothelial fibroblasts play a significant role in contributing to intramyocardial adipocytes.

Summary: This study describes a two-step chemically defined xeno-free method for generating valve endothelial-like cells from human pluripotent stem cells. The derived valvular cells exhibit superior proliferative and clonogenic potential, and could be used as seed cells for construction of valve organoids or next generation tissue engineered heart valves.

Summary: Sountoulidis et al. have created a spatial gene expression atlas of the human embryonic lung during the first trimester of gestation, identifying 83 cell states and developmental trajectories. They integrated single-cell RNA sequencing and spatially resolved transcriptomics, providing an open platform for interactive exploration. The atlas can serve as a reference for further research and understanding of pulmonary diseases.

Summary: By using single-cell RNA-sequencing of embryonic mouse lungs, this study reveals that the pulmonary mesenchyme contains a continuum of cell identities, but no transcriptionally distinct progenitors. Transcriptional variability is correlated with spatially distinct sub-epithelial and sub-mesothelial mesenchymal compartments that are regulated by Wnt signaling. Live-imaging and tension-sensors show that sub-epithelial mesenchyme contributes to airway smooth muscle. Reconstruction of differentiation trajectories reveals early activation of cytoskeletal and Wnt signaling genes.

Summary: The study demonstrated that utilizing bead-bound Jagged1 was effective in activating Notch3 and promoting SMC differentiation/maturation, while magnetic pulling forces did not activate Notch3 but instead provided necessary clustering or traction forces for Notch activation. The findings suggest that manipulation of Jagged1 presentation strategy can improve biomaterial-driven control of SMC behavior.

Summary: The study found that VSMCs differentiated from adipose-derived stem cells (ASCs) show potential for populating PET-based vascular scaffolds. By shortening the differentiation period and studying the role of downstream effectors of TGF-beta, the process was stabilized. The non-woven PET structure did not affect ASC differentiation, providing a novel alternative to address issues with long-term patency of vascular grafts.

Summary: This study reveals that Dopey2 and Pcdh7 regulate the proliferation and differentiation of neural stem cells and progenitors during embryonic neurogenesis, leading to the proper size and architecture of zebrafish brains. Dopey2 promotes the proliferation of neural stem cells/progenitors, while Pcdh7 promotes their differentiation. These proteins work together to orchestrate the development and arrangement of neural cells in zebrafish embryonic brains.

Summary: This study found the presence of micro- and nanoplastics in human blood and placentas, indicating embryonic exposure to these particles. Furthermore, the exposure to polystyrene nanoplastics (PS-NPs) was found to negatively impact the cardiac differentiation of human embryonic stem cells (hESCs), leading to immature cardiomyocytes and impaired contractility. Mechanistically, PS-NPs induced mitochondrial oxidative stress, activated P38/Erk MAPK signaling pathway, and blocked autophagy flux, reducing the pluripotency of hESCs. Consistent results were observed in zebrafish embryo models, with reduced cardiac contraction and blood flow after exposure to PS-NPs.

Summary: The embryonic endocardium plays a vital role in early heart development by inducing the formation of trabecular myocardium, the source of valvular cells and part of the coronary vasculature. Human endocardial cells offer unique therapeutic opportunities, such as engineering biological valves and cell-based therapy for damaged hearts. By generating hPSC-derived endothelial cells, key signaling pathways for the development of endocardial cells were identified, with a novel role for BMP10 in lineage specification.

Summary: The study showed that culturing hPSC-CMs on PDMS-lined roller bottles and transplanting these cells into a guinea pig model of myocardial infarction resulted in better structural and functional outcomes compared to conventional immature hPSC-CM populations. The PDMS-matured hPSC-CMs exhibited increased cardiac gene expression and more mature properties in vitro, and the intracardiac grafts formed with these cells showed enhanced structure and alignment, better electromechanical integration, and improved contractile function. This study provides practical methods for the scaled generation of mature hPSC-CMs and highlights the importance of using more mature cardiomyocytes for cardiac regeneration.

Summary: Multiple large cardiovascular outcome trials have shown that SGLT2 inhibitors and GLP-1 receptor agonists significantly reduce cardiovascular disease risk in patients with type 2 diabetes, including major adverse cardiovascular events and heart failure. These drugs have received strong recommendations in diabetes and cardiology guidelines, but their usage remains low.

Summary: The health status of Black patients with heart failure is worse compared to White patients. Sodium-glucose cotransporter 2 inhibitors (SGLT2is) can reduce cardiovascular mortality and improve health status in heart failure patients, but it is unclear if the effect is similar across races. The study found that SGLT2i improves health status equally for Black and White patients.
