| Outline of Final Research Achievements |
Periosteal-derived cells (PDCs) were cultured on AM to generate novel periosteal cell sheets, and the kinetics of the cell sheets were immunohistochemically investigated in vivo. The AM was collected from the placenta during a caesarean section. For PDCs, primary culture of the periosteal tissue was passaged 3-4 times. These cells were cultured on AM. The resulting culture sheets were transplanted under the renal capsules of nude mice, and were removed after 4 weeks.
PDCs proliferated on AM, forming single cell sheets, which demonstrates that AM is suitable as a culture substrate. The periosteum contains cells that have the ability to differentiate into osteoblasts and osteocytes. The cell sheets expressed osteoblast proteins, which were maintained even in an in vivo environment.
