    Extracellular Vesicles Deposit PCNA to Rejuvenate Aged Bone Marrow-Derived Mesenchymal Stem Cells and Slow Age-Related Degeneration

    Scientists demonstrated that neonatal umbilical cord (UC) is a source of extracellular vesicles (EVs) derived from MSCs. These UC-produced MSC-EVs contain abundant anti-aging signals and rejuvenate senescing adult bone marrow-derived MSCs.

    Genome-Wide CRISPR-Cas9 Screen Identified KLF11 as a Druggable Suppressor for Sarcoma Cancer Stem Cells

    Kruppel-like factor 11 (KLF11) recruited SIN3A/HDAC to suppress the transcriptional output of YAP/TEAD, which, in turn, promoted KLF11 transcription, forming a negative feedback loop.
