  • Publication number: 20210212948
    Abstract: Disclosed are cell membrane-derived nanovesicles, a method of preparing the nanovesicles, and a pharmaceutical composition and a diagnostic kit using the nanovesicles. The cell membrane-derived nanovesicles may prevent potential adverse effects because intracellular materials (e.g., genetic materials and cytosolic proteins) unnecessary for delivering therapeutic or diagnostic substances are removed from the nanovesicles. In addition, as the nanovesicles may be targeted to specific cells or tissues, therapeutic or diagnostic substances may be predominantly delivered to the targeted cells or tissues, while delivery of the substances may be inhibited. Therefore, the nanovesicles may alleviate suffering and inconvenience of patients by reducing adverse effects of therapeutic substances and by improving efficacy of the substances.

  • Patent number: 10675244
    Abstract: The present invention relates to a microvesicle that is derived from nucleated mammalian cells, which are smaller than the nucleated cells. The microvesicles of the present invention can be used in the delivery of a therapeutic or diagnostic substance to specific tissues or cells, and more particularly, relates to microvesicles derived from monocytes, macrophages, dendritic cells, stem cells or the like, which can be used to deliver specific therapeutic or diagnostic substances for treating and/or diagnosing tissue associated with cancer, diseased blood vessels, inflammation, or the like.

  • Publication number: 20180036240
    Abstract: The present invention relates to cell membrane-derived nanovesicles, a method of preparing the same, and a pharmaceutical composition and a diagnostic kit using the nanovesicles. The cell membrane-derived nanovesicles according to the present invention may prevent the occurrence of potential side effects because intracellular materials (e.g., genetic materials and cytosolic proteins) unnecessary for delivery of therapeutic or diagnostic substances are removed from the nanovesicles. In addition, since the nanovesicles may be targeted to the specific types of cells or tissues, therapeutic or diagnostic substances may be predominantly delivered to the targeted cells or tissues while delivery of therapeutic or diagnostic substances to untargeted sites may be inhibited.
