Summary: Asbestos is found to be the main cause of malignant mesothelioma, and HMGB1 plays a crucial role in its development. HMGB1 is mainly released by mesothelial cells during the early stages of inflammation after asbestos exposure, leading to an inflammatory response and atypical mesothelial hyperplasia. Knocking out HMGB1 in mesothelial cells significantly reduces the inflammatory response and the incidence of mesothelioma.

Summary: This study investigates the behaviors of hematopoietic progenitor cells using collagen hydrogels of different stiffness and characterizes their transcriptional profiles through single-cell RNA sequencing. The results demonstrate that 3D collagen hydrogels promote the differentiation of progenitor cells into macrophages and enhance communication with other hematopoietic clusters.

Summary: This study models human heart development using human pluripotent stem cells, revealing the differentiation and progression of different cardiac lineages. The findings demonstrate the conservation of cardiac lineage development between humans and mice, providing important resources for establishing disease models and developing new therapies.

Summary: In this study, the co-expression of three transcription factors - Runx1, Hoxa9, and Hoxa10 - in gene-edited pluripotent stem cells (PSCs) led to the generation of induced hematopoietic progenitor cells (iHPCs) that successfully engrafted and repopulated multiple lineages in wild-type animals. These iHPCs exhibited normal distribution and persisted for 6 months without leukemogenesis. Transcriptome analysis showed that the generative myeloid, B, and T cells from iHPCs resembled natural cell counterparts.

Summary: Mesothelial cells are a type of epithelial cells that line serous cavities and visceral organs. They have immunoregulatory properties and can inhibit lymphocyte proliferation and suppress activated B cells. They can also modify macrophage activation.

Summary: Depression is a common mental illness affecting over 300 million people worldwide. Various theories exist regarding its pathogenesis, including the monoamine hypothesis, changes in the hypothalamic-pituitary-adrenal axis, inflammation, immune system alterations, and abnormalities of neurogenesis. In addition to well-known theories, there are also less widely recognized theories of depression causation.

Summary: For a long time, it was believed that self-renewing and multipotent hematopoietic stem cells (HSCs) were the main contributors to both embryonic and adult hematopoiesis. However, recent studies have shown that native hematopoiesis is not solely driven by hierarchical differentiation of HSCs, but rather by hematopoietic progenitor cells (HPCs). These findings help redefine our understanding of the cellular origins of embryonic and adult hematopoiesis and highlight the differences in revealing HSC potential versus HSC fate using different approaches.

Summary: Multiple system atrophy (MSA) is a debilitating movement disorder with unknown etiology. It presents with characteristic parkinsonism and/or cerebellar dysfunction due to deterioration in specific brain regions. The early pathological events and development mechanisms of MSA are reviewed, focusing on the involvement of oligodendrocyte lineage cells and alpha-synuclein. This understanding will guide future research in MSA.

Summary: Proper brain development requires precisely controlled phases of stem cell proliferation, lineage specification, differentiation, and migration. This study reveals a novel developmental mechanism for telencephalon patterning that relies on the interplay of dose- and time-dependent signaling, including a time lag for specification and a temporal shift in cellular Shh sensitivity. The timing of signal exposure for efficient induction is specific to each lineage, and tissues with marked size expansion can compensate for the changing dynamics of morphogen signals through delayed fate choice.

Summary: By investigating the chromatin accessibility of single cells, it has been found that there is a population of cells that display both stem-like and lineage-affiliated chromatin signatures. These cells are positioned between stem cells and committed progenitors, showing multi-lineage potential but lacking self-renewal activity.

Summary: Obesity promotes rapid growth and metastases of mammary tumors in mice by increasing recruitment of myeloid lineage cells and deposition of collagen fibers within the lungs. Lung stromal cells isolated from obese mice show higher expression of extracellular matrix proteins and inflammatory cytokines, facilitating metastatic growth prior to tumor formation. Understanding these mechanisms may provide new therapeutic options for obese breast cancer patients.

Summary: Arsenic exposure disrupts hematopoiesis by inhibiting the function of GATA-2, leading to aberrant differentiation and cell accumulation, which may contribute to the onset and/or exacerbation of hematological disorders such as anemia.
