Injectable BMSC‐Based Extracellular Matrix‐Mimicking Microtissue for Myocardial Infarction Repair

open access: yesAdvanced Science, EarlyView.
A novel injectable biomimetic extracellular matrix scaffold (JLSV) is designed for enhanced delivery of bone marrow‐derived mesenchymal stem cells (BMSCs). By utilizing janus basic nanotubes, laminin, stromal‐derived factor‐1 alpha, and vascular endothelial growth factor, this innovative JLSV–BMSC microtissue shows promise in myocardial infarction ...

Microfilament‐Myosin II Regulates the Differentiation of Multinucleated Cysts into Oocytes and Influences Oocyte Developmental Potential in Mice

open access: yesAdvanced Science, EarlyView.
In this study, we provided new evidence identifying multinucleated cysts as precursors for oocyte differentiation. Within these cysts, organelles migrate and aggregate to form Balbiani body (B‐body) and establish early cellular polarity. Concurrently, excess nuclei are expelled, enabling cyst‐to‐oocyte differentiation. The microfilament‐myosin II plays

Pigment Epithelium‐Derived Factor Deficiency Impairs Hippocampal Glutamate Homeostasis and Cognitive Function by Downregulating Astrocytic GLT‐1

open access: yesAdvanced Science, EarlyView.
The chronic glutamate‐induced excitotoxicity hypothesis has profoundly informed the therapeutic strategies employed in Alzheimer’s disease (AD). This study shows pigment epithelium‐derived factor (PEDF) regulates astrocytic glutamate transporter‐1 (GLT‐1)‐mediated glutamate homeostasis and cognition. Reduced PEDF correlates with lower Mini‐Mental State

Integrative Omics Reveals Glutamine Catabolism‐Driven Apoptotic Suppression in Monocytes upon Mechanical Unloading

open access: yesAdvanced Science, EarlyView.
This research integrated multi‐omics analysis of bone tissue from HLU and control mice revealed that mechanical unloading suppresses intrinsic apoptosis and augments glutamine (Gln) catabolism in osteoclast lineage cells. The findings highlight pivotal roles for SLC1A5‐mediated Gln metabolism and XIAP/Diablo axis‐mediated apoptosis suppression.
