Intramyocardial implantation of differentiated rat bone marrow mesenchymal stem cells enhanced by TGF-β1 improves cardiac function in heart failure rats

Braz. j. med. biol. res; 49 (6), 2016
The present study tested the hypotheses that i) transforming growth factor beta 1 (TGF-β1) enhances differentiation of rat bone marrow mesenchymal stem cells (MSCs) towards the cardiomyogenic phenotype and ii) intramyocardial implantation of the TGF-β1-treated MSCs improves cardiac function in ...

Medium modification with bone morphogenetic protein 2 addition for odontogenic differentiation

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate whether medium modification improves the odontogenic differentiation of human dental pulp stem cells (DPSC) in vitro and in vivo. DPSC isolated from human impacted third molar teeth were analysed for clusters of differentiation with flow cytometry. Odontogen...

In vivo performance of different scaffolds for dental pulp stem cells induced for odontogenic differentiation

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was designed to determine the in vivo performance of three different materials as scaffolds for dental pulp stem cells (DPSC) undergoing induced odontogenic differentiation. An odontogenic medium modified by the addition of recombinant human bone morphogenetic protein 2 was used in th...

RUNX2 and WWOX genes as molecular biomarkers and candidates for targeted therapy in Egyptian patients with primary conventional osteosarcoma

Appl. cancer res; 36 (), 2016
Background: The conventional osteosarcoma (OS) is the commonest primary malignant, bone tumor with complex genomic profiles and poor survival. Runt-related transcription factor 2 (RUNX2) and WW domain containing oxidoreductase (WWOX) genes are implicated in normal osteogenesis as well as in the developme...

Follicular helper T cell in immunity and autoimmunity

Braz. j. med. biol. res; 49 (5), 2016
The traditional concept that effector T helper (Th) responses are mediated by Th1/Th2 cell subtypes has been broadened by the recent demonstration of two new effector T helper cells, the IL-17 producing cells (Th17) and the follicular helper T cells (Tfh). These new subsets have many features in common, ...

Chitosan-collagen biomembrane embedded with calcium-aluminate enhances dentinogenic potential of pulp cells

Braz. oral res. (Online); 30 (1), 2016
Abstract The development of biomaterials capable of driving dental pulp stem cell differentiation into odontoblast-like cells able to secrete reparative dentin is the goal of current conservative dentistry. In the present investigation, a biomembrane (BM) composed of a chitosan/collagen matrix embedded w...

Growth hormone in the presence of laminin modulates interaction of human thymic epithelial cells and thymocytes in vitro

Biol. Res; 49 (), 2016
BACKGROUND: Several evidences indicate that hormones and neuropeptides function as immunomodulators. Among these, growth hormone (GH) is known to act on the thymic microenvironment, supporting its role in thymocyte differentiation. The aim of this study was to evaluate the effect of GH on human thymocyte...

Potential role of marine algae extract on 3T3-L1 cell proliferation and differentiation: an in vitro approach

Biol. Res; 49 (), 2016
BACKGROUND: From ancient times, marine algae have emerged as alternative medicine and foods, contains the rich source of natural products like proteins, vitamins, and secondary metabolites, especially Chlorella vulgaris (C. vulgaris) contains numerous anti-inflammatory, antioxidants and wound healing sub...

Assessment of Tumor Associated Tissue Eosinophilia (TATE) in Oral Squamous Cell Carcinoma Using Carbol Chromotrope Stain

Tumor related tissue eosinophilia (TATE) is a known phenomenon but its role in prognostics and correlation with size of the primary tumor is still controversial. Using a stain, like Carbol chromotrope, that targets eosinophils exclusively and vividly, offers an advantage over haematoxylin and eosin, whic...

Atividade de novos derivados de tiazolidinodionas sobre a diferenciação de pré-osteoblastos e pré-adipócitos

As tiazolidinodionas (TZDs) são sensibilizadores de insulina utilizados no tratamento do diabetes mellitus tipo 2. Contudo, apesar dos efeitos benéficos sobre a glicemia, importantes efeitos adversos incluindo perda óssea e aumento de adiposidade são relatados com o uso clínico das TZDs. Assim, é n...
