Collagen Vesicles Released by Bone Marrow Stem Cells May Explain Their Therapeutic Potential, Study Shows

Collagen type VII-filled vesicles released by bone marrow-derived mesenchymal stem cells may explain the therapeutic benefits of these cells in recessive dystrophic epidermolysis bullosa (RDEB), a study suggests. The study, “Dual mechanism of type VII collagen transfer by bone marrow mesenchymal stem cell extracellular vesicles to recessive…

Researchers Identify a Blood Biomarker for Epidermolysis Bullosa-associated Squamous Cell Carcinoma

Using a simple blood sample may be sufficient to detect a biomarker for skin cancer in epidermolysis bullosa patients, a new study suggests. This is because the cancer-specific variant of the SLCO1B3 gene is found exclusively in extracellular vesicles detected in blood circulation. The study reporting the findings is titled “Extracellular Vesicles as…
