Overview about the microscopic structure and architecture of allogeneic spongious granules by scanning electron microscopy (SEM) in A low (350-fold) and B high (800-fold) magnification. A Allogeneic bone compositions consist of about 5% water and 30% collagen that is visible by the fan-shaped spreading edges (white arrows) and B by a multi-layered structure created by collagen fibers (white asterisk). SEM is even highlighting the porous structure of allogeneic spongious granules that is suitable for fast and sufficient micro-vessel ingrowth and bone remodeling
