COMPOSITIONS CONTAINING MACROPHAGES AND USES THEREOF

摘要

The invention relates to the use of macrophages for the preparation of a drug for the treatment of a disease or of a lesion involving cellular apoptosis, reduction of the survival of cells and/or destruction of cells. The present invention also provides the use of macrophages for the preparation of a drug for the improvement of survival of a first type of cells, for the treatment of a disease or of a lesion involving the destruction of a second type of cells or of a tissue containing a second type of cells, said first type of cells being chosen among the group consisting of: precursor cells, stem cells and any type of differentiated cells. The inventors surprisingly showed that macrophages may inhibit precursor cells apoptosis in a cell to cell contact and may serve as stromal support for efficient cellular engraftment for tissue repair. They showed in particular that macrophages could inhibit myogenic precursor cell apoptosis.
