Inducing differentiation of human umbilical cord blood mesenchymal stem cells into chondroblast in vitro.
Future studies with the use of specific markers for chondrogenic lineages are necessary not only to show chondrogenic lineages but mainly to specify cell types, such as, chondroblast, fibroblast and osteoblast; as well as to demonstrate collagen type II expression of these cells.
(10) Using cytologic material, immunohistochemical marker studies also confirm the histomorphological and immunohistochemical suspicion that the stromal cells are of mononuclear/macrophage rather than chondroblast origin.
Moreover, osteoblast and chondroblast precursors exhibited the impaired formation of extracellular matrix and the reduced expression of the following transcripts: bone morphogenetic protein 2 (BMP-2), vimentin, decorin, and Sox9.
The histopathological description of chondroblastoma according to the World Health Organisation is "a relatively benign tumour, characterised by highly cellular and relatively undifferentiated tissue, made up of rounded or polygonal chondroblast - like cells with distinct outlines and multi-nucleated giant cells of osteoclast type arranged singly or in groups.
Through chemotaxis, the BMPs can bring cells to implantation site and do with that undifferentiated mesenchymal cells become into specific cellular types that synthesize bone and cartilaginous tissue, as the osteoblast and chondroblast cells (Inoda et al.; Kamakura et al.).
It has been recognized that upon incubation of these cells in the conditioned media (CM) from dental pulp stem cell-derived osteoblasts and auricle cartilage chondrocytes, these cells develop the capability of differentiating into osteoblast and chondroblast lineages [16].
In the process of skeletogenesis, the BMPs are concerned in recruiting and demarcation of mesenchymal cells into chondroblasts and osteoblast and stir up program cell death at the site of future joints.

This inflammation then acts as a stimulator of proliferation of mesenchymal cells that have inherent property of metaplasia and can differentiate into chondroblasts or osteoblasts [22].
