New Insights into How Leprosy Infection Spreads Could Pave the Way for Early Intervention (image) Cell Press Share Print E-Mail Caption Stem cell-like cells contribute to bacterial spread into skeletal muscles and macrophages. (Left) Bacteria-laden stem cells (green) directly fused with skeletal muscles (red) and disseminated leprosy bacteria (stained by mycobacterial acid-fast staining; in red) inside the muscle fibers (top right). Stem cell-like cells (green) secrete chemoactractants, recruit macrophages (red) and transfer bacteria (bottom right). Shown is a macrophage (red) that has received bacteria (green) from stem cells.
