  • Publication number: 20240191201
    Abstract: The present invention relates to methods for obtaining extracellular vesicles (EVs) from cells such as mesenchymal stromal cells (MSCs), wherein the cells are cultured in the presence of polypeptides from the extracellular matrix proteins laminin alpha-5, laminin alpha-4 or their functional fragments, or in the presence of polypeptides comprising the extracellular domain of human MCAM protein. The invention further relates to EVs obtained by the above methods. The EVs are useful in the treatment and prophylaxis of medical conditions such as inflammatory diseases, ischemic heart disease and acute respiratory distress syndrome.

  • Publication number: 20240141296
    Abstract: The present invention relates to methods for culturing and isolating cells such as multipotent stem cells or multipotent progenitor cells. The methods of the invention comprise using the human CD105 polypeptide as a cell culture substrate. The cells obtained according to the methods of the invention are capable of forming colony forming unit-fibroblasts (CFU-Fs). Cell lines comprising such cells are useful for the treatment of medical conditions, such as acute respiratory distress syndrome (ARDS).

  • Patent number: 11274139
    Abstract: The present invention pertains to inter alia therapeutic delivery vesicles, for instance exosomes or microvesicles, comprising polypeptide constructs, methods for producing said therapeutic delivery vesicles, pharmaceutical compositions and medical uses thereof. The therapeutic polypeptide constructs comprised in the extracellular delivery vesicles enable sequestering target molecules of interest, to treat e.g. neuro-inflammatory diseases and cancer.
