By employing 3D suspension condition with the support of low concentration Matrigel, a novel culture system was developed to generate expandable hepatoblast organoids (HB-orgs) and mature polarised hepatocyte organoids (P-hep-orgs) from human embryonic stem cells (hESCs) in both dishes and bioreactors. scRNA-seq and functional assays were used to characterise HB-orgs and P-hep-orgs. hESC-derived HB-orgs could proliferate at least for 15 passages, leading to 10¹² in total cells in 4 weeks. P-hep-orgs differentiated from HB-orgs displayed characteristics of mature hepatocytes with polarisation. Moreover, single-cell RNA sequencing exhibited that over 40% of cells in P-hep-orgs were highly fidelity with human primary hepatocytes. Eventually, large-scale production of P-hep-orgs could be generated from massively expanded HB-orgs within 1 week with similar number in bioreactors, which were achieved by the enhancements in energy metabolism contribute to the expansion of HB-orgs and maturation of P-hep-orgs in bioreactors.

Despite various treatment options available, the treatment of keloids remains a major clinical challenge due to high recurrence rates and inconsistent therapeutic outcomes. By collecting three keloid tissues and three normal skin samples and utilising single-cell RNA sequencing (scRNA-seq), we delved into the cellular heterogeneity and molecular mechanisms of keloids. Our study identified multiple fibroblast subpopulations within keloid tissue. Enrichment and cell-cell communication analyses revealed that POSTN-positive mesenchymal fibroblasts (POSTN+ mesenchymal fibs) are more prevalent in keloids and exhibit higher transforming growth factor β (TGF-β) signalling activity, potentially playing a central role in excessive fibrosis. In contrast, IGFBP2-positive fibroblasts (IGFBP2+ fibs) are more abundant in normal skin, insensitive to TGF-β and Periostin signalling, and possess anti-fibrotic potential, possibly related to limited tissue repair and regenerative capacity. Trajectory analysis inferred the differentiation states and patterns of different fibroblast subpopulations. Additionally, we explored the heterogeneity of endothelial cells, finding an endothelial cell subpopulation (EC10) exhibiting mesenchymal activation characteristics, which may work with specific fibroblasts to promote abnormal angiogenesis and endothelial-to-mesenchymal transition processes. Spatial transcriptomics analysis has shown that the proportion of IGFBP2+ fibroblasts relatively increases in acne keloidalis after hormonal treatment, further demonstrating their value as potential therapeutic targets. Ultimately, we separated these two subpopulations using flow cytometry, highlighting their opposing roles in the secretion of the ECM.

However, the early and widespread degeneration of the LC-NE system presents a significant challenge for direct intervention in ND. Recent advances in regenerative cell therapy offer promising new strategies for ND treatment. The regeneration of LC-NE from pluripotent stem cells (PSCs) could significantly broaden the scope of LC-NE-based therapies for ND.

However, the influence of herpesviruses on RNA Pol II transcription extends beyond these direct effects. Here, we present a novel mechanism by which the host cell cycle regulates viral gene transcription via RNA Pol II during infection by Anatid Herpesvirus 1 (AnHV-1), an avian alpha-herpesvirus. The results demonstrated that the formation of viral replication compartments (vRCs) and the subsequent recruitment of RNA pol II are positively correlated with AnHV-1 DNA synthesis. As viral DNA replication progresses, host cells are arrested in the S phase, which not only halts host gene transcription but also facilitates viral transcription. This cell cycle arrest in the S phase promotes viral DNA (vDNA) synthesis and vRC formation, which further enhances the preferential recruitment of RNA Pol II to viral promoters, enabling efficient viral gene transcription. We propose that this S phase arrest and the hijacking of RNA Pol II represent a novel mechanism by which AnHV-1 enhances viral transcription, offering a unique survival strategy compared to the known strategy in herpesviruses.

This damage manifests as mucus hypersecretion, pulmonary inflammation and fibrosis, which often lead to long-term complications collectively referred to as long COVID or post-acute sequelae of COVID-19 (PASC). The airway epithelium, as the first line of defence against respiratory pathogens, depends on airway basal stem cells (BSCs) for regeneration. Alterations in BSCs are associated with impaired epithelial repair and may contribute to the respiratory complications observed in PASC. Given the critical role of BSCs in maintaining epithelial integrity, understanding their alterations in COVID-19 is essential for developing effective therapeutic strategies. This study investigates the intrinsic properties of BSCs derived from COVID-19 patients and evaluates the modulatory effects of mesenchymal stem cells (MSCs). Through a combination of functional assessments and transcriptomic profiling, we identified key phenotypic and molecular deviations in COVID-19 patient-derived BSCs, including goblet cell hyperplasia, inflammation and fibrosis, which may underlie their contribution to PASC. Notably, MSC co-culture significantly mitigated these adverse effects, potentially through modulation of the interferon signalling pathway. This is the first study to isolate BSCs from COVID-19 patients in the Chinese population and establish a COVID-19 BSC-based xenograft model. Our findings reveal critical insights into the role of BSCs in epithelial repair and their inflammatory alterations in COVID-19 pathology, with potential relevance to PASC and virus-induced respiratory sequelae.
