Osteogenic differentiation of human periosteal-derived cells in a three-dimensional collagen scaffold.

This study examined the osteogenic differentiation of cultured human periosteal-derived cells grown in a three dimensional collagen-based scaffold. Periosteal explants with the appropriate dimensions were harvested from the mandible during surgical extraction of lower impacted third molar. Periosteal-derived cells were introduced into cell culture.

In vitro osteogenic differentiation of cultured human dental papilla-derived cells.

Purpose: This study examined the osteogenic phenotypes and mineralization of cultured human dental papilla-derived cells.

Materials And Methods: Dental papillae were harvested from mandibles during surgical extraction of lower impacted third molars from 3 patients aged 13 to 15 years. The dental papilla-derived cells were introduced into the cell culture.
