Proposal for a new histological scoring system for cartilage repair

Clinics; 73 (), 2018
OBJECTIVE: This study aimed to develop a new histological scoring system for use in a partial-thickness cartilage repair animal model. Although previous papers have investigated the regeneration of articular cartilage, the good results achieved in small animals have not been replicated in large animal mo...

Cardiac tissue engineering: current state-of-the-art materials, cells and tissue formation

Einstein (Säo Paulo); 16 (3), 2018
ABSTRACT Cardiovascular diseases are the major cause of death worldwide. The heart has limited capacity of regeneration, therefore, transplantation is the only solution in some cases despite presenting many disadvantages. Tissue engineering has been considered the ideal strategy for regenerative medicine...

Decellularization of placentas: establishing a protocol

Braz. j. med. biol. res; 51 (1), 2018
Biological biomaterials for tissue engineering purposes can be produced through tissue and/or organ decellularization. The remaining extracellular matrix (ECM) must be acellular and preserve its proteins and physical features. Placentas are organs of great interest because they are discarded after birth ...

Nanotechnology and multipotent adult progenitor cells in Reparative Medicine: therapeutic perspectives

Einstein (Säo Paulo); 16 (4), 2018
ABSTRACT The biology of stem cells is one of the most dynamic and promising fields of the biological sciences, since it is the basis for the development of organisms. Its biological complexity demands efforts from several lines of research aimed mainly at its therapeutic use. Nanotechnology has been emer...

Matrices de tercera generación en la ingeniería de tejidos ósea
Third-generation matrices in bone tissue engineering

Actual. osteol; 13 (2), 2017
Existen numerosas patologías que generan situaciones invalidantes debido a problemas asociados a nivel de defectos óseos. Esto genera, en muchas oportunidades, cuestiones sanitarias de alto impacto. La ingeniería de tejidos óseos pretende generar propuestas novedosas para reparar pérdidas o fractura...

Gás ozônio como agente esterilizante de nanofibras eletrofiadas para engenharia tecidual: avaliação da segurança e da eficácia

Com o aumento da expectativa de vida e o envelhecimento da população, a medicina regenerativa vem ocupando um importante espaço visando manter a qualidade de vida da população. A engenharia de tecidos, apoiada nos avanços da biotecnologia e da nanotecnologia, vem se configurando como alternativa ma...

Evaluation of electrospun PLLA-ECM scaffolds as biomaterials for bone regeneration

The extracellular matrix (ECM) is secreted by the host tissue and is an important key for mechanisms of cell responses. The main properties of the ECM materials include biodegradability, biocompatibility, and nanostructured in a 3D fibre network. In addition, ECM is composed of important molecules like g...

Immunohistochemical expression of TGF-β1 and osteonectin in engineered and Ca(OH)2-repaired human pulp tissues

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of the present study was to evaluate the expression of transforming growth factor-β1 (TGF-β1) and osteonectin (ON) in pulp-like tissues developed by tissue engineering and to compare it with the expression of these proteins in pulps treated with Ca(OH)2 therapy. Tooth slices we...

Biocompatibility of human auricular chondrocytes cultured onto a chitosan/polyvynil alcohol/epichlorohydrin-based hydrogel for tissue engineering application

Int. j. morphol; 32 (4), 2014
Tissue engineering (TE) has become an alternative for auricular reconstruction based on the combination of cells, molecular signals and biomaterials. Scaffolds are biomaterials that provide structural support for cell attachment and subsequent tissue development. Ideally, a scaffold should have character...

Biocompatibilidad de células madres mesenquimales de tejido gingival humano en cultivoconun andamiaje de polímero sintético de ácido poliláctico (OPLA)

Int. j. morphol; 32 (3), 2014
La ingeniería tisular se plantea como tratamiento ideal para la regeneración de tejidos con la utilización de andamiajes, células madres y factores de crecimiento. Las células madres de origen gingival plantean ventajas de obtención, mientras que el OPLA 3D permite cultivos de alta densidad celular...
