1. In vitro Evaluation of PHBV/PCL Blends for Bone Tissue Engineering
The objective of this study was to evaluate Vero cells in in vitro biocompatibility tests with pure PHBV and PCL and 75/25 and 50/50 blends developed for bone tissue bioengineering in dense or porous forms. The biomaterials were characterized morphologically by scanning electron microscopy, (SEM) stereoscopic imaging (SI), and micrometer measurement. Cellula

2. Immunohistological study of the effect of vascular Endothelial Growth Factor on the angiogenesis of mature root canals in rat molars
Abstract Tissue bioengineering has been applied to Endodontics to seek a more biological treatment. The presence of blood vessels is crucial for cell nutrition during tissue formation. Objective This study analysed the application of vascular endothelial growth factor (VEGF) in the angiogenesis of mature root canals. Material and methods Upper first molars

3. Rat dental pulp stem cells: isolation and phenotypic characterization method aiming bone tissue bioengineering
ABSTRACT: Dental pulp stem cells (DPSC) have been showing a considerable potential for regenerative medicine. Pulps were collected from lower incisors (n=2) through direct access of the tooth pulp chamber. The isolated cells were cultured in alfa-MEM 10% FBS, in standard culture conditions. At the third passage, DPSC were characterized by flow cytometry (MHC

4. Estruturação tridimensional de scaffolds de policaprolactona via manufatura aditiva / Additive manufacturing of PCL 3D scaffolds
Em decorrência da grande demanda de transplantes de órgãos e tecidos no Brasil, ha estímulos para criação de terapias alternativas como o desenvolvimento de substitutos biológicos temporários, isto e, scaffolds, através da Bioengenharia e Engenharia Tecidual, descartando a necessidade de doadores. Neste trabalho, foi utilizado o polímero policaprol

5. Avaliação de matrizes tridimensionais colagênicas como carreadores celulares para a bioengenharia óssea / Evaluation of three-dimensional collagenic matrices as cellular scaffolds to bone bioengineering
The therapy of bone defects constitutes one of the great challenges of the medicine and dentistry. Although autogenous is considered "gold standart", presents limitations as the necessity of second surgical site, limitation of bone availability and lack of previsibility. Tissue bioengineering appeared as a promising treatment for critical bone defects conjug

6. Avaliação in vivo de matrizes tridimensionais de quitosana para a bioengenharia tecidual óssea.
This study evaluated the histomorphological behavior in vivo of tridimensional matrices of chitosan with 4% and 15% degrees of acetylene process, in a 9mm critical size defect of diameter created in rat calvaria. Sixty rats Wistar Albinus, disposed in three groups were evaluated. In the GI group (control group) the defect was filled only with blood coagulant

7. The Use of Adult Stem Cells to Study the Etiopathogeny of Cleft Lip and Palate and Tissue Engineering / Uso de células tronco adultas para estudo da etiopatogenia das fissuras lábio palatinas e bioengenharia de tecidos
Clefts involving the lip and palate (CLP) or palate only (CP) represent the most frequent facial malformation during birth and correspond to approximately 25% of all congenital defects. The incidence of this problem is high; corresponding to approximately 1:700 births, but is different among the ethnic groups. Clefts represent a major health problem due to t

9. Tissue engineering, stem cells, cloning, and parthenogenesis: new paradigms for therapy
Patients suffering from diseased and injured organs may be treated with transplanted organs. However, there is a severe shortage of donor organs which is worsening yearly due to the aging population. Scientists in the field of tissue engineering apply the principles of cell transplantation, materials science, and bioengineering to construct biological substi

10. Insulin-like Growth Factor I Controls Adhesion Strength Mediated by α5β1 Integrins in Motile Carcinoma Cells
One of the intriguing questions regarding cell motility concerns the mechanism that makes stationary cells move. Here, we provide the first physical evidence that the onset of breast cancer cell motility in response to insulin-like growth factor I (IGF-I) correlates with lowering of adhesion strength from 2.52 ± 0.20 to 1.52 ± 0.13 μdynes/μm2 in cells at
