Natural marine sponge skeleton: a biomimetic scaffold for human osteoprogenitor cell attachment, growth and differentiation.
Many factors affecting mesenchymal and osteoprogenitor cell proliferation have been determined in serum after TBI, however, the results are controversial, and ossification and CNS damage are linked to an accidental association (30).
A cohesive consistency when saturated with the patient's bone marrow providing both a continuous scaffold for bone formation and the osteoprogenitor cells needed to initiate new bone growth.
The third passage cells were induced by lineage-specific induction factor to osteoprogenitor cells (OC-AD-MSCs) according to ALVES et al.
17,18) The endosteum seems to have a key role in providing osteoprogenitor cells for spontaneous regeneration of bone from residual walls defects.
sup][5],[6],[7] It has been demonstrated that chitosan can improve the proliferation, the differentiation and the mineralization of osteoprogenitor cells, osteoblasts as well as new bone formation.
It seems that some factors, including bone morphogenetic protein, platelet-derived growth factor, and transforming growth factor-beta have the ability to be chemotactic for fibroblasts and may have some role in aggregating osteoprogenitor cells at sites of heterotopic ossification.
Guillemot, Laser-assisted bioprinting for creating on-demand patterns of human osteoprogenitor cells and nano-hydroxyapatite, Biofabrication, 3, 11-17 (2011).
Four theories of pathogenesis have been suggested in the literature, 1) displacement of bony fragments into adjacent soft tissues and hematoma with subsequent proliferation, 2) detachment of periosteal fragments into surrounding tissues with proliferation of osteoblasts, 3) migration of subperiosteal osteoprogenitor cells into adjacent soft tissues through periosteal tears due to trauma, and 4) metaplasia of extraosseous cells exposed to growth factors derived from the breakdown of bone fragments displaced within soft tissue during trauma.
The mixture of autogenous cancellous bone and hydroxyapatite contained viable osteoblasts and osteoprogenitor cells which are essential for the mechanisms of osteogenesis and osteoinduction.
