Abstract: A method of promoting angiogenesis and cell proliferation in a subject in need of tissue repair and/or regenerative therapy involves administering to the subject a pharmaceutical composition in the form of a hydrogel that includes orange-derived extracellular vesicles (EVs) having a diameter ranging from 10 to 500 nm and showing pro-angiogenic activity. The orange-derived EVs are dispersed in a hydrogel matrix and are releasable from the hydrogel matrix. A method for preparing the pharmaceutical composition in the form of a hydrogel is also provided.

Abstract: The invention is in the field of therapeutic treatment of tumours. The inventors have found that microvesicles derived from adult stem cells exert a remarkable anti-tumour effect when administered to a patient affected by a tumour disease. Preferred microvesicles are derived from a bone marrow-mesenchymal stem cell, a glomerular mesenchymal stem cell or a non-oval liver stem cell.

Abstract: There is disclosed a preparation of extracellular vesicles derived from human liver stem cells, preferably from a non-oval human progenitor cell line that expresses hepatic cell markers, which is capable of reducing the senescence of a population of senescent cells, as measured in a SA-?-galactosidase-based cellular senescence assay. Also disclosed are therapeutic applications of the preparation of extracellular vesicles derived from human liver stem cells according to the invention. Therapeutic applications include the reduction of cellular senescence, e.g. in an vitro or ex vivo method, as well as the therapeutic treatment of diseases and conditions known to be related to ageing and cellular senescence, such as for example atherosclerosis, diabetes mellitus type 2, asthenia, and others.

Abstract: The present invention relates to compositions of extracellular vesicles (EVs) which are characterized by a strong proangiogenic activity and are effective in the therapeutic treatment of ischemic diseases and ischemic injuries or in wound healing. The extracellular vesicles (EVs) suitable for use in the compositions of the invention are either derived from a blood component or are selected by means of a potency test for pro-angiogenesis. Also disclosed is a method of manufacturing a pharmaceutical preparation of extracellular vesicles (EVs) characterized by a strong proangiogenic activity.

Abstract: The invention relates to compositions and methods for isolating extracellular vesicles (EVs) from a biological fluid sample. The compositions and methods of the invention are based on the combination of a polycation with an extracellular matrix forming polymer. Extracellular vesicles (EVs) are isolated from biological fluids such as blood, serum, plasma, saliva, urine or cerebrospinal fluid, or from the conditioned medium of a cell culture, such as an adult stem cell culture. The use of the isolation methods and compositions of the invention results in a higher EVs recovery, enrichment in exosomes, simplicity, cost-effectiveness, and in the isolation of EVs that retain their biological activities in vitro.
