Molecular Design of Highly Efficient Heavy‐Atom‐Free Near‐Infrared Cyanine Photosensitizers for Fluorescence Image‐Guided Photodynamic Therapy of Solid Tumors

Advanced Healthcare Materials, EarlyView.
Highly efficient heavy‐atom‐free NIR photosensitizers based on a heptamethine cyanine platform were developed for image‐guided photodynamic therapy. Both in vitro and in vivo results revealed that the R820‐3 photosensitizer with a highly twisted molecular structure exhibited potential for NIR fluorescence image‐guided photodynamic cancer therapy ...

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.
