Patterning of Artificial Cell Populations Via Laser Induced Forward Transfer for Controlled and Localized Cargo Uptake and Release

Small, EarlyView.
Polypeptide‐based complex coacervate artificial cells were prepared in situ within a viscoelastic matrix and adhered to the biomaterial ink, which was subsequently LIFT‐printed. The artificial cells preserved their structural stability during printing and retained biologically relevant properties, showing controlled cargo uptake and release ...

Proteomic Sex Estimation From Embedded Tooth Enamel

Archaeometry, EarlyView.
ABSTRACT Teeth hold insights into childhood diet, health and demography—including chromosomal sex. Proteomic analysis can detect peptide biomarkers from amelogenin genes encoded on X and Y chromosomes, allowing sex estimation. Embedding resins, necessary for thin sectioning teeth, can damage analytical systems, preventing proteomic analysis. We present

Brain metastasis‐associated fibroblasts shape the tumour microenvironment to enhance cancer cell invasion

Brain Pathology, EarlyView.
Brain metastasis‐associated fibroblasts are active stromal components of the metastatic niche characterised by extracellular matrix remodelling and production of pro‐migratory mediators. They promote monocyte and cancer cell migration and enhance cancer cell invasion while having no growth‐promoting effect on cancer cells.
