9) Chondroblast are uniform and show sparse intracytoplasmic vacuoles.
The presence of chondroblasts and hyaline matrix with or without focal calcification will differentiate chondroblastoma from benign giant-cell tumours.
Finally, the fourth calcified layer is the deepest and is formed by chondroblasts, chondrocytes and osteoblasts distributed throughout the articular cartilage.
13) Smears are cellular and contain chondroblasts with round to oval nuclei with fine, evenly distributed chromatin and longitudinal nuclear grooves.
Still others types of cells seen in PA included chondroblasts, chondrocytes, osteoblasts and osteocytes associated with their respective mesenchymal components.
There are several theories explaining heterotopic ossification mechanisms: 1) bone formation occurs because of the implantation of small particles containing osteogenic cells from the perichondrium or periosteum that are planted during a laparotomy or trauma; 2) bone formation is caused by differentiated stem cells in the mesoblast, as well as in the osteoblasts or chondroblasts, which result from local lesions, inflammatory processes, or infectious stimuli.
Maternal organism intoxication with lead acetate causes the following destructive changes of the skeletal system in first generation of breed: damage to the zonal structure; disruption of the structure of the tissue matrix; structural damage to cartilaginous and osteogenic cells; disturbances in proliferation, differentiation and synthetic activity of chondroblasts, chondrocytes of osteogenic cells; delay of growth and shaping of bone tissue.
Studies carried out with osteoblast cell cultures demonstrated that IGFs increase the proliferation, differentiation, matrix production, and mineralization functions of the chondroblasts at every stage of development [10, 11].
Studies in mammals have shown these potentials to be correlated to the presence of mesenchymal stem cells in the marrow, which are shown to be able to differentiate into chondroblasts and osteoblasts.
1) They undergo asymmetric division to produce cells that become more specialized, such as osteoblasts or chondroblasts, while maintaining the ability to self perpetuate.
Microscopically the individual tumour cells have small hyperchromatic nuclei with a small rim of eosinophilic cytoplasm which show the features of chondroblasts.
All types, except for chondroblasts and or osteocytes, were observed in CC, whereas all of them were seen in CTM.
