Single-Cell Transcriptomics Identifies Selective Lineage-Specific Regulation of Genes in Aortic Smooth Muscle Cells in Mice.

Background: Smooth muscle cells (SMCs) of the proximal thoracic aorta are derived from second heart field (SHF) and cardiac neural crest lineages. Recent studies, both in vitro and in vivo, have implied relevance of lineage-specific SMC functions in the pathophysiology of thoracic aortic diseases; however, whether 2 lineage-derived SMCs have any predisposed transcriptional differences in the control aorta remains unexplored.

Methods: Single-cell RNA sequencing and single-nucleus assay for transposase-accessible chromatin sequencing were performed on isolated cells from the aortic root and ascending aortas of 14-week-old SHF-traced () and cardiac neural crest-traced () male mice.

The association between the polymorphism of RAR related orphan receptor beta and the clinical manifestations of oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) affects a substantial proportion of the Asian population and is influenced by various genetic risk factors. The (), a regulator of the circadian rhythm, has been implicated in certain neoplasms. Accordingly, this study investigated the association between single-nucleotide polymorphisms and clinical manifestations of OSCC.

Advanced Lung-on-a-Chip Technology: Mimicking the Complex Human Lung Microenvironment.

Intricate crosstalk among various lung cell types is crucial for orchestrating diverse physiological processes. Traditional two-dimensional and recent three-dimensional (3D) assay platforms fail to precisely replicate these complex communications. Many lung models do not effectively reflect the multicellular complexity of lung tissue.
