  • Patent number: 11793837
    Abstract: The invention relates to cell-free compositions obtained by culturing adult-derived human liver stem/progenitor cells (ADHLSC) in cell culture medium and isolating the resulting conditioned medium (ADHLSC-CM) that has advantageous properties, such as anti-fibrotic effects. ADHLSC-CM, compositions based on ADHLSC-CM, and other related and derived products, can be used in cell culture processes or as a medicament, more particularly for the treatment of diseases involving organ injury, organ failure, in organ or cell transplantation or the pathological disruption, inflammation, degeneration, and/or proliferation of cells within a tissue or an organ, in particular within liver.

  • Publication number: 20220202874
    Abstract: The invention relates to the use of a composition comprising adult human liver- derived progenitor cells, such as heterologous human adult liver-derived progenitor cells (HALPC), for the treatment of a patient having non-alcoholic fatty liver disease (NAFLD), such as non-alcoholic fatty liver (NAFL) or non-alcoholic steatohepatitis (NASH), or wherein the patient is at risk of developing NASH. The treatment comprises a step of administering to said patient an amount of said composition which comprises a dose of 0.25 to 2.5 million said progenitor cells per kg body weight; wherein the composition is substantially free of an effective amount of an anticoagulant, and wherein the patient does not receive any co-treatment with an anticoagulant.

  • Patent number: 9931360
    Abstract: A method of treating liver-based inborn, metabolic deficiencies is disclosed by treatment of an individual, such as a patient suffering from liver-based inborn, metabolic deficiencies, with human progenitor or stem cells, a cell population or their progeny. The cells used in the treatment have the following characteristics. They are positive for vimentin, ?-smooth muscle actin (ASMA), and for at least one mesenchymal marker such as CD90, CD29, CD73, and CD44. They are positive for at least one hepatocyte marker such as albumin, alpha-fetoprotein, alpha-1 antitrypsin, HNF-4 and MRP2 transporter. They express at least one hepatocyte-like property or function such as G6P, CYP1B1, CYP3A4, TDO, TAT, GS, GGT, CK8, and EAAT2. They are negative for at least one marker such as cytokeratin-19, CD45, CD34, CD49f, CD133, HLA-DR, and CD117. They have mesenchymal-like morphology. They originate from human adult liver cells.
