cells... but inside the cells, the Golgi apparatus.. think of it as a post office... it packages and ships things out of a cell into the human body
The periosteum porects the bone from surrounding structures, anchors blood vessels and nerves to the surface of the bone, and provides stem cells for bone width growth and fracture repair. (McKinley, Michael. Human Anatomy. McGraw-Hill. 2008. p151)
