1. Direct inhibitory effect of caffeine on viability, synthesis activity and gene expression in cultures of chondrocytes extracted from the articular cartilage of rats
RESUMO O objetivo deste estudo foi avaliar o efeito direto de concentrações de cafeína sobre a viabilidade, atividade de síntese e expressão gênica em culturas de condrócitos de ratos. As cartilagens dos fêmures e tíbias de 15 ratos Wistar com três dias foram extraídas para isolamento de condrócitos. Os condrócitos foram cultivados em meio condr

2. Micromass cultures are effective for differentiation of human amniotic fluid stem cells into chondrocytes
OBJECTIVES: Articular cartilage is vulnerable to injuries and undergoes an irreversible degenerative process. The use of amniotic fluid mesenchymal stromal stem cells for the reconstruction of articular cartilage is a promising therapeutic alternative. The aim of this study was to investigate the chondrogenic potential of amniotic fluid mesenchymal stromal

3. Detection of SNPs in the BMP6 Gene and Their Association with Carcass and Bone Traits in Chicken
ABSTRACT BMP6, a member of the subfamilies of the morphogenetic proteins (BMPs), plays a crucial role in osteogenic and chondrocyte differentiation in vitro and stimulates chondrogenesis, making chondrocytes differen-tiate on their terminal stage. The objective of this study is to explore the relationship between polymorphism of BMP6 gene and slaughter trait

4. Deferoxamine synergizes with transforming growth factor-β signaling in chondrogenesis
Abstract Osteoarthritis, also known as degenerative arthritis or degenerative joint disease, is an epidemic disease that affects millions of people worldwide. Despite extensive recent work on the cellular biology of osteoarthritis, the precise mechanisms involved are still poorly understood and there is no effective treatment for this disease. The role of tr

5. PDK2 promotes chondrogenic differentiation of mesenchymal stem cells by upregulation of Sox6 and activation of JNK/MAPK/ERK pathway
This study was undertaken to clarify the role and mechanism of pyruvate dehydrogenase kinase isoform 2 (PDK2) in chondrogenic differentiation of mesenchymal stem cells (MSCs). MSCs were isolated from femurs and tibias of Sprague-Dawley rats, weighing 300-400 g (5 females and 5 males). Overexpression and knockdown of PDK2 were transfected into MSCs and then c

6. Delivery of the Sox9 gene promotes chondrogenic differentiation of human umbilical cord blood-derived mesenchymal stem cells in an in vitro model
SRY-related high-mobility-group box 9 (Sox9) gene is a cartilage-specific transcription factor that plays essential roles in chondrocyte differentiation and cartilage formation. The aim of this study was to investigate the feasibility of genetic delivery of Sox9 to enhance chondrogenic differentiation of human umbilical cord blood-derived mesenchymal stem ce

7. Telomerase reverse transcriptase mediated immortalization of human bone marrow stromal cells
Primary human bone marrow stromal cells (hMSCs) were transfected with human telomerase reverse transcriptase (hTERT) gene with lipofection method. The hTERT transfected hMSCs of passage 100 underwent chondrogenesis induction with dexamethasone, transforming the growth factor β and vitamin C, osteogenesis induction with dexamethasone, β glycerophosphoric ac

8. Condrogênese a partir de células-tronco do líquido amniótico humano estimulado com TRF-ß3 em micromass / Chondrogenesis differentiation of mesenchymal stem cells from human amniotic fluid with TGF-beta3 in micromass culture system
Introduction: The use of mesenchymal stem cells (MSC) for reconstruction of articular cartilage, leads to a promising therapeutic alternative, due to the tissue vulnerability to injuries and irreversible degenerative process. The aim of this study was to investigate the chondrogenic potential of MSC from human amniotic fluid in Micromass system (high-density

9. Characterization of human adipose-derived stem cells and expression of chondrogenic genes during induction of cartilage differentiation
OBJECTIVES: Understanding the changes in chondrogenic gene expression that are involved in the differentiation of human adipose-derived stem cells to chondrogenic cells is important prior to using this approach for cartilage repair. The aims of the study were to characterize human adipose-derived stem cells and to examine chondrogenic gene expression after o

10. Periosteum as a source of mesenchymal stem cells: the effects of TGF-β3 on chondrogenesis
INTRODUCTION: Numerous experimental efforts have been undertaken to induce the healing of lesions within articular cartilage by re-establishing competent repair tissue. Adult mesenchymal stem cells have attracted attention as a source of cells for cartilage tissue engineering. The purpose of this study was to investigate chondrogenesis employing periosteal m

11. Comparação da expressão dos genes Dapper com a de marcadores moleculares para desenvolvimento dos membros de aves (Gallus gallus) / Comparison of the expression pattern of the Dapper genes with the expression of molecular markers for limb development in chicken (Gallus gallus)
The acquisition of vertebrates limbs represents an important novelty for this group and allowed the expansion of vertebrates through the Biosphere. The molecular basis of limbs development are under intense investigation, and the role of several genes and signaling molecules begin to be understood both within the context of axis determination as well as in t

12. Effects of strain and age on ear wound healing and regeneration in mice
Round holes in the ears of MRL mice tend to close with characteristics of regeneration believed to be absent in other mouse strains (e.g., C57BL/6). We evaluated the kinetics and the histopathology of ear wound closure in young (8 weeks old) C57BL/6 and BALB/c mice. We also used middle-aged (40 weeks old) C57BL/6 mice to evaluate the influence of aging on th
