Advanced Biology, EarlyView.The regenerative potential of adipose tissue‐derived stem cells can be enhanced through chemical stimulation in vitro. A short stimulation protocol using forskolin, either alone or in combination with other growth factors, under xeno‐free conditions enhanced the pro‐angiogenic responses in human ASCs.

Advanced Biology, EarlyView.The axolotl's remarkable regenerative abilities decline with age, the causes may include the numerous repetitive elements within its genome. This study uncovers how Ty3 retrotransposons and coexpression networks involving muscle and immune pathways respond to aging and regeneration, suggesting that transposons respond to physiological shifts and may ...

Advanced Biology, EarlyView.In this study, a new type of bioactive glass fiber ‐based composite magnesium phosphate bone cement is prepared and verified that its mechanical strength and biological properties. In addition, the cement may have played a biologically active role in the Notch and HIF signaling pathways.

Advanced Functional Materials, EarlyView.Mesenchymal stem cell‐derived nanoghosts (MSC‐NGs) mimic naturally secreted extracellular vesicles (MSC‐EVs) in structure and physicochemical properties but can be synthesized at more translatable yields. As osteogenic agents, MSC‐NGs demonstrate superior outcomes compared to MSC‐EVs.

Cell Membrane Vesicle Camouflaged Artificial Cells
Advanced Functional Materials, EarlyView.Artificial cells camouflaged with a cell membrane vesicle coating are able to assemble into synthetic aggregates that exhibit rudimentary communication capabilities. Additionally, when these artificial cells are equipped with antioxidant capabilities, they are able to protect the intracellular homeostasis in HepG2 cells present in semi‐synthetic ...
