  • Publication number: 20250290061
    Abstract: Therapeutic extracellular vesicles (EVs) containing high copies of functional nucleic acids and other biomolecules are produced in large quantities by laying donor cells on a surface of a chip, adding various plasmids, other transfection vectors and their combinations to a buffer on the chip, applying a pulsulatic electric field across the cells laid on top of the chip surface and plasmids/vectors buffer solution below the chip surface, and collecting the EVs secreted by the transfected cells. The chip surface has a three-dimensional (3D) nanochannel electroporation (NEP) biochip formed on it, capable of handling large quantities of the donor cells. The buffer is adapted for receiving plasmids and other transfection vectors.

  • Publication number: 20250044294
    Abstract: The present invention is related to a use of prochlorperazine (PCP), or analog thereof for treating a cancer in a subject by influencing membrane proteins and receptors and inducing alterations in the expressions of the surface marker on cancer cells and their derived extracellular vesicles. The invention method offers a novel approach for the treatment and diagnosis of cancer and metastasis. Specific surface markers serve as a potential candidate for cancer-associated extracellular vesicles (EVs) and have applications in diagnosis, prognosis, and therapeutic targeting.

  • Patent number: 12195789
    Abstract: The present invention discloses a method of detecting the presence of mutated genes, mRNAs or microRNAs in a subject. The method comprises the following steps: (1) Provide a body fluid sample containing cells, circulating tumor cells (CTCs), and/or extracellular vesicles (EVs); and use an analyzer having overhang molecular beacons to measure fluorescence signals generated by interactions between the body fluid sample and the overhang molecular beacons, so as to detect the presence of the mutated genes, mRNAs or microRNA. Furthermore, a biochip comprising a gold coating substrate and tethered lipoplex nanoparticles encapsulating the overhang molecular beacons is also provided in the invention.

  • Publication number: 20240408237
    Abstract: The present invention is related to a method and pharmaceutical composition for treating a cartilage damage in a subject (including a human or an animal), particularly osteoarthritis (OA), using extracellular vesicles (EVs) with SOX9 gene, called as “EV-SOX9”. The EV-SOX9 is obtained by encapsulating the SOX9 mRNA or the mRNA of its upstream and downstream gene in EVs, naïve EVs with high expression level of SOX9 mRNA or its upstream and downstream gene from different cell sources, or MSC-derived EV-SOX9, which is obtained by transferring the SOX9 gene or its upstream and downstream gene into a multipotent cell and collecting EVs.
