Influence of the microenvironment on gene and protein expression of odontogenic-like and osteogenic-like cells.

چکیده
Progenitor cells play an important biological role in tooth and bone formation, and previous analyses during bone and dentine induction have indicated that they may be a good alternative for tissue engineering. Thus, to clarify the influence of the microenvironment on protein and gene expression, MDPC-23 cells (mouse dental papilla cell line) and KUSA/A1 cells (bone marrow stromal cell line) were used, both in vitro cell culture and in intra-abdominal diffusion chambers implanted in 4-week-old male immunodefficient mice (SCID mice). Our results indicate that KUSA/A1 cells differentiated into osteoblast-like cells and induced bone tissue inside the chamber, whereas, MDPC-23 showed odontoblast-like characteristics but with a low ability to induce dentin formation. This study shows that MDPC-23 cells are especial cells, which possess morphological and functional characteristics of odontoblast-like cells expressing dentin sialophosphoprotein in vivo. In contrast, dentin sialophosphoprotein gene and protein expression was not detected in both cell lines in vitro. The intra-abdominal diffusion chamber appears as an interesting experimental model for studying phenotypic expression of dental pulp cells in vivo.

Differentiation of Adipose-derived Stem Cells into Schwann Cell Phenotype in Comparison with Bone Marrow Stem Cells
Objective(s) Bone marrow is the traditional source of human multipotent mesenchymal stem cells (MSCs), but adipose tissue appears to be an alternative and more readily available source. In this study, rat adipose-derived stem cells (ADSCs) were induced to differentiate into Schwann-like cells and compared with rat bone marrow stem cells (BMSCs) for their Schwann-like cells differentiation pote...
متن کاملA Mimic of the Tumor Microenvironment on GPR30 Gene Expression in Breast Cancer
Introduction: The G-protein coupled receptor 30 (GPR30) gene is a member of the G-protein coupled receptor (GPCR) family; involved in breast, endometrial, and ovarian cancers. Many GPCR receptors that are implicated in several types of human cancers are correlated with increased cell proliferation and tumor progression; especially GPR30 gene. Methods: The breast cancer MCF-7 and MDA-MB-231 cel...

Background: Endometriosis is the growth of endometrial cells outside the uterine cavity. It has been suggested that immune system plays important roles in both initiation and progression of the disease. Several studies have been shown that women with endometriosis diverge in their expression of different genes including heat-shock proteins, fibronectin, and neutrophil elastase, which might be i...
