After the death of HC, there will be empty lagoons, spaces that will later be occupied and invaded by blood vessels and osteoprogenitor
cells, osteoclasts, osteoblasts and bone marrow cells (Mackie et al.
Treatment of heterotopic bone formation involves the disruption of osteoprogenitor
cells and associated signal pathways.
Thus, the aim of this study was to evaluate osteoprogenitor
cells derived from mesenchymal stem cells from adipose tissue (OC-AD-MSCs) in the treatment of critical bone defects in dogs radio.
Osteoconductive and osteoinductive, nanostructured Calcium phosphate based (Ca-P) biomaterials [5,6] may need to be complemented with polymeric and ceramic composite bone replacement materials, which enable adhesion, growth and development of osteoprogenitor
16,26] Various studies [15,17,26] have corroborated that viable osteocytes and osteoprogenitor
cells are present in the reamed material.
17,18) The endosteum seems to have a key role in providing osteoprogenitor
cells for spontaneous regeneration of bone from residual walls defects.
Movements of the bone ends will disrupt the fibro vascular structures, decrease the recruitment of osteoprogenitor
cells and allow for fibrous tissue ingrowth instead of bony healing.
sup],, 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.
