Abstract: A method for obtaining cell populations derived from the muscular tissue and their use for preparing cell therapy products includes culturing cells previously removed by biopsy from skeletal muscular tissues, identifying the different types of cells present at different stages of culture, selecting the culture stage on the basis of the required cell population and collecting the selected culture stage for preparing a cell therapy product. The invention also concerns cell populations derived from muscular tissue obtained by implementing the method whereof the dominant cell type is CD34+, CD15+ or CD56+ or Class 1+HLA, or comprises a doubly negative CD56?/CD15? cell type or may comprise more minority CD10+, Stro-1+ and CD 117+ cell types.

Abstract: The present application relates to cell populations having differentiation capacities, which are obtainable by isolation from a muscle tissue, more particularly from a skeletal and/or cardiac muscle tissue, preferably from endomysial and/or cardiac tissue, more preferably from endomysial tissue. The cell populations of the invention comprise ALDH-positive cells, and notably have myogenic and/or adipogenic and/or osteogenic differentiation capacities. The present application also relates to those of said cell populations, which comprise CD34-negative cells, and to those of said cell populations, which comprise CD34-positive cells. The cell populations of the invention, which comprise ALDH-positive cells and CD34-negative cells, notably have myogenic and/or osteogenic differentiation capacities. The cells populations of the invention, which comprise ALDH-positive cells and CD34-positive cells, notably have adipogenic and/or osteogenic differentiation capacities.

Abstract: The invention concerns a method for obtaining in vitro a population of cells comprising essentially human smooth muscular cells expressing calponin and SM-MHC from a sample of human muscular biopsy or from human muscular biopsies differentiated in vitro into skeletal muscle cells. The invention also concerns a composition comprising the isolated smooth muscular cells obtainable by said method as therapeutic principle designed for humans. The invention further concerns the use of the isolated smooth muscular cells for preparing a therapeutic composition designed to replace smooth muscular cells. In particular, the invention concerns the use of said isolated smooth muscular cells for treating ischemia, cancer or any disease requiring revascularization of damaged tissues. Finally, the invention concerns the use of said smooth muscular cells as vector for an active principle for preparing a therapeutic composition designed for humans requiring treatment with said active principle.
