Development of regenerative therapeutic strategies to reverse the progression of advanced heart failure is one of the most urgent clinical needs of this century. Insights gained from clinical trials of adult stem cells, together with fundamental scientific advances in cardiac stem cell and regenerative biology, are beginning to yield potential new targets and strategies for regenerative therapies. Of particular importance are new scientific discoveries related to intrinsic cardiac regeneration, renewal factors that can trigger regeneration, and tissue-engineering technology, which are beginning to change the way investigators view the scientific and clinical position of cardiovascular regenerative therapy.

Therapeutic efficacy and safety of adeno-associated virus (AAV) liver gene therapy depend on capsid choice. To predict AAV capsid performance under near-clinical conditions, we established side-by-side comparison at single-cell resolution in human livers maintained by normothermic machine perfusion. AAV-LK03 transduced hepatocytes much more efficiently and specifically than AAV5, AAV8 and AAV6, which are most commonly used clinically, and AAV-NP59, which is better at transducing human hepatocytes engrafted in immune-deficient mice.

This study examines the biocompatibility, osteogenic potential, and effectiveness of polyether ether ketone (PEEK) composites for treating osteonecrosis, seeking to establish a theoretical basis for clinical application. A range of PEEK composite materials, including sulfonated polyether ether ketone (SPEEK), polydopamine-sulfonated polyether ether ketone (SPEEK-PDA), bone-forming peptide-poly-dopamine-sulfonated polyether ether ketone (SPEEK-PDA-BFP), and vascular endothelial growth factor-poly-dopamine-sulfonated polyether ether ketone (SPEEK-PDA-VEGF), were constructed by concentrated sulfuric acid sulfonation, polydopamine modification and grafting of bioactive factors. The experiments involved adult male New Zealand rabbits aged 24-28 weeks and weighing 2.

To investigate heterogeneity of fibroblasts in human fetal skin, we analysed published single-cell RNA sequencing data (8 and 16 post conception weeks (PCW)) and performed single-molecule fluorescence in situ hybridisation to map their spatial distribution and predicted dynamic interactions. Clustering revealed 8 fibroblast populations with developmental stage-specific abundance changes. Proliferative cells (MKI67+) were present at all stages.
