Resumen
Antecedentes: la ingeniería tisular permite obtener órganos como injertos a partir de tejidos descelularizados, regenerados con células autólogas. Objetivo: descelularizar y regenerar tráqueas porcinas. Material y métodos: se descelularizaron tráqueas porcinas colocándolas cada una en el ...
Three-dimensional (3D) bioprinting of cells is an emerging area of research but has not been explored yet in the context of periodontal tissue engineering. Objetive: This study reports on the optimization of the 3D bioprinting scaffolds and tissues used that could be applied clinically to seniors for the...
Tissue engineering replaces injured tissues by manipulating cells, making scaffolds, and using molecules that stimulate the tissue. Mesenchymal stem cells (MSCs) are good candidates for tissue engineering, as this is one of the cell types which are recruited to repair injured tissues. Scaffolds are struc...
The central nervous system shows limited regenerative capacity after injury. Spinal cord injury (SCI) is a devastating traumatic injury resulting in loss of sensory, motor, and autonomic function distal from the level of injury. An appropriate combination of biomaterials and bioactive substances is curre...

Abstract Autologous fibrin matrices derived from the Leukocyte and Platelet Rich Plasma (L-PRP) and Leukocyte and Platelet Rich Fibrin (L-PRF) techniques present great potential to act as a bioactive scaffold in regenerative medicine, contributing to the maintenance of cell viability, proliferation stimu...
Abstract Tissue engineering suggests different forms to reconstruct tissues and organs. One of the ways is through the use of polymeric biomaterials such as poly(L-lactic acid) (PLLA). PLLA is a recognized material in tissue engineering due to its characteristics as biocompatibility and bioresorbability....
SUMMARY: Arterial obstruction in small diameter (<6 mm) vessels are many times treated with grafts, however autologous aren't always available and synthetic have a high rate of complications. Decellularization of umbilical arteries may provide a solution, but the ideal method is debatable. We compare ...

Introducción: En la actualidad existen diferentes métodos y técnicas de preservación articular. La utilización de una matriz de atelocolágeno combinada con microperforaciones otorga un soporte adecuado para la inducción de la condrogénesis a partir de las células mesenquimales provenientes de la...
Introdução: a regeneração e o reparo de tecidos ósseos perdidos é objeto de estudo da Bioengenharia Tecidual. O uso de biomateriais substitutos ósseos biomiméticos visa estimular os sistemas celulares e bioquímicos para restabelecer de modo mais eficiente o tecido ósseo nos casos de sua reconst...
