AI Article Synopsis

  • The study investigates the use of biosheets made from in-body tissue architecture (iBTA) to improve the effectiveness of mesenchymal stem cells (MSCs) in wound healing for dogs.
  • Biosheets were created by embedding molds in beagle dogs, and their healing effects were evaluated by comparing the wound healing progress between groups with and without biosheet application over 8 weeks.
  • Results showed that while initial wound contraction rates were higher in the control group, the biosheet group showed a tendency for faster overall healing, indicating potential benefits of using stem cell-containing biosheets in wound repair.

Article Abstract

The administration of mesenchymal stem cells (MSCs) has a positive effect on wound healing; however, the lack of adequate MSC engraftment at the wound site is a major limiting factor in current MSC-based therapies. In this study, a biosheet prepared using in-body tissue architecture (iBTA) was used as a material to address these problems. This study aimed to assess and evaluate whether biosheets containing somatic stem cells would affect the wound healing process in dogs. Biosheets were prepared by subcutaneously embedding molds in beagles. These were then evaluated grossly and histologically, and the mRNA expression of inflammatory cytokines, interleukins, and Nanog was examined in some biosheets. Skin defects were created on the skin of the beagles to which the biosheets were applied. The wound healing processes of the biosheet and control (no biosheet application) groups were compared for 8 weeks. Nanog mRNA was expressed in the biosheets, and SSEA4/CD105 positive cells were observed histologically. Although the wound contraction rates differed significantly in the first week, the biosheet group tended to heal faster than the control group. This study revealed that biosheets containing somatic stem cells may have a positive effect on wound healing.

Background: Kidney tumors, common in the urinary system, have widely varying survival rates post-surgery. Current prognostic methods rely on invasive biopsies, highlighting the need for non-invasive, accurate prediction models to assist in clinical decision-making.

Purpose: This study aimed to construct a K-means clustering algorithm enhanced by Transformer-based feature transformation to predict the overall survival rate of patients after kidney tumor resection and provide an interpretability analysis of the model to assist in clinical decision-making.

Purpose: Tibial open shaft fractures are very common and susceptible to infection, which can lead to significant morbidity especially infection and non-union. Antibiotic coated nail is one option for fixing open shaft tibial fractures to minimise infection. This study aimed to compare the clinical outcome of Gentamicin-coated tibial nails versus regular unreamed interlocking tibial nails in the treatment of type I and II tibial open fractures.

Stromal architecture and fibroblast subpopulations with opposing effects on outcomes in hepatocellular carcinoma.

Dissecting the spatial heterogeneity of cancer-associated fibroblasts (CAFs) is vital for understanding tumor biology and therapeutic design. By combining pathological image analysis with spatial proteomics, we revealed two stromal archetypes in hepatocellular carcinoma (HCC) with different biological functions and extracellular matrix compositions. Using paired single-cell RNA and epigenomic sequencing with Stereo-seq, we revealed two fibroblast subsets CAF-FAP and CAF-C7, whose spatial enrichment strongly correlated with the two stromal archetypes and opposing patient prognosis.
