YAP-driven malignant reprogramming of oral epithelial stem cells at single cell resolution.

Tumor initiation represents the first step in tumorigenesis during which normal progenitor cells undergo cell fate transition to cancer. Capturing this process as it occurs in vivo, however, remains elusive. Here we employ spatiotemporally controlled oncogene activation and tumor suppressor inhibition together with multiomics to unveil the processes underlying oral epithelial progenitor cell reprogramming into tumor initiating cells at single cell resolution.

Evaluation of the efficacy, safety, and satisfaction rate of topical latanoprost in patients with hypopigmented burn scars treated with fractional CO2 laser: a double-blind randomized controlled clinical trial.

Burn scars present psychological and social challenges for patients, classified into atrophic and hypertrophic types. Treatments like corticosteroid injections, laser therapy, and platelet-rich plasma (PRP) injections are commonly recommended for hypertrophic scars, while regenerative medicine and fractional CO2 lasers are linked to some degree of improvement for atrophic scars. Hypopigmented and depigmented burn scars pose ongoing challenges for healthcare providers and patients, with therapies such as intense pulsed light and fractional CO2 laser showing variable effects in treating these conditions.

Endothelial-secreted Endocan activates PDGFRA and regulates vascularity and spatial phenotype in glioblastoma.

Extensive neovascularization is a hallmark of glioblastoma (GBM). In addition to supplying oxygen and nutrients, vascular endothelial cells provide trophic support to GBM cells via paracrine signaling. Here we report that Endocan (ESM1), an endothelial-secreted proteoglycan, confers enhanced proliferative, migratory, and angiogenic properties to GBM cells and regulates their spatial identity.

Mechanisms and Countermeasures for Muscle Atrophy in Microgravity.

Previous studies have revealed that muscle atrophy emerges as a significant challenge faced by astronauts during prolonged missions in space. A loss in muscle mass results in a weakening of skeletal muscle strength and function, which will not only contribute to a decline in overall physical performance but also elevate the risk of various age-related diseases. Skeletal muscle atrophy in the microgravity environment is thought to be associated with changes in energy metabolism, protein metabolism, calcium ion homeostasis, myostatin levels, and apoptosis.

A novel quantitative angiogenesis assay based on visualized vascular organoid.

Angiogenesis describes the sprouting of blood vessels from existing vasculatures and it plays a pivotal role in disease progress such as diabetes, age-related macular degeneration and cancer. However, the most widely used anti-angiogenic agents targeting vascular endothelial growth factor (VEGF) pathway still lacked of specificity and therapeutic efficacy. To establish a method suitable for high-throughput drug screening and faithfully recapitulate the feature of in vivo angiogenesis, we generated a PECAM1-mRuby3-secNluc; ACTA2-EGFP dual reporter human pluripotent stem cell (hPSC) line and utilizing the cell line to establish a visualized and quantifiable in vitro angiogenesis model with stem cell-derived vascular organoid.

Donor MHC-specific thymus vaccination allows for immunocompatible allotransplantation.

Organ transplantation is the last-resort option to treat organ failure. However, less than 10% of patients benefit from this only option due to lack of major histocompatibility complex (MHC)-matched donor organs and 25%-80% of donated organs could not find MHC-matched recipients. T cell allorecognition is the principal mechanism for allogeneic graft rejection.

Human respiratory organoids sustained reproducible propagation of human rhinovirus C and elucidation of virus-host interaction.

The lack of a robust system to reproducibly propagate HRV-C, a family of viruses refractory to cultivation in standard cell lines, has substantially hindered our understanding of this common respiratory pathogen. We sought to develop an organoid-based system to reproducibly propagate HRV-C, and characterize virus-host interaction using respiratory organoids. We demonstrate that airway organoids sustain serial virus passage with the aid of CYT387-mediated immunosuppression, whereas nasal organoids that more closely simulate the upper airway achieve this without any intervention.
