Effect of Initial Cell Seeding Density on Early Osteogenic Signal Expression of Rat Bone Marrow Stromal Cells Cultured on Cross-Linked Poly(propylene fumarate) Disks

The intercellular signaling mechanisms among a transplanted cell population are largely determined by the cell population itself as well as the surrounding environment. Changes in cell-to-cell paracrine signaling distance can be obtained by altering cell density, and signal expression of growth factors can be enhanced by auto/paracrine signal transduction. To examine these relationships, we investigated the effect of cell seeding density on...
