Obtención, caracterización y biocompatibilidad de hidrogeles poliméricos para ingeniería de tejidos: estudio preliminar
Obtaining, characterization and biocompatibility of polymeric hydrogels for tissue engineering

Actual. osteol; 20 (1), 2024
La ingeniería de tejidos es una ciencia inter-disciplinaria que se encuentra en constante búsqueda de materiales que puedan ayudar a reparar el tejido dañado; en nuestro caso, tejido óseo y cartilaginoso. En este trabajo obtuvimos un biomaterial utilizando algina...

Avances en endodoncia regenerativa: reporte de caso con uso de la membrana amniótica humana
Advances in regenerative endodontics: report of a case using a human amniotic membrane

Los procedimientos endodónticos regenerativos (REPs) representan una evolución significativa en el campo de la endodoncia, buscando no sólo tratar la infección o lesión presente en el diente, sino tam-bién promover la regeneración de los tejidos denta-rios afectados. El presente caso clín...

Culture of rat mesenchymal stem cells on PHBV-PCL scaffolds: analysis of conditioned culture medium by FT-Raman spectroscopy

Braz. j. biol; 83 (), 2023
Abstract Mesenchymal stem cells (MSCs) have great potential for application in cell therapy and tissue engineering procedures because of their plasticity and capacity to differentiate into different cell types. Given the widespread use of MSCs, it is necessary to better understand some properties related...

Automated Assessment of Cell Infiltration and Removal in Decellularized Scaffolds - Experimental Study in Rabbits

Abstract Objective Semiquantitative and automated measurement of nuclear material removal and cell infiltration in decellularized tendon scaffolds (DTSs). Method 16 pure New Zealand rabbits were used, and the gastrocnemius muscle tendon was collected bilaterally from half of these animals (16 tendons c...

The effect of scaffold hydroxyapatite derived from portunus pelagicus shell on the expression of fibroblast growth factor-2 (fgf-2) and bone morphogenetic proteins-2 (bmp -2) in the extraction sockets of cavia cobaya

J. oral res. (Impresa); 11 (5), 2022
Objetive: To determine the expression of Fibroblast Growth Factor (FGF)-2 and Bone Morphogenetic Protein (BMP)-2 after application of scaffold hydroxyapatite from Rajungan crab shell (Portunus pelagicus) in the tooth extraction socket of Cavia cobaya. Material and Methods: This study used a post-test onl...

Células madre en odontología: nuevas perspectivas
Stem cells in dentistry: new perspectives

Rev. Círc. Argent. Odontol; 80 (231), 2022
En el campo de la odontología, prevalecen actualmente alternativas terapéuticas con una filosofía conservadora. Sin embargo, con el advenimiento de los tratamientos con células madre (CM), se amplían las posibilidades terapéuticas, que buscan la combinación y el equilibrio entre la intervención t...

Decoloración coronaria inducida por la utilización de Biodentine y MTA blanco en procedimientos de regeneración pulpar: estudio ex vivo
Coronal discoloration induced by the use of Biodentine and white MTA in pulp regeneration procedures: an ex-vivo study

Se comparó el grado de decoloración de la corona clínica en piezas dentarias anteriores humanas ex-traídas, sometidas a procedimientos de regeneración endodóntica, utilizando MTA blanco o sustituto bioac-tivo de la dentina (Biodentine) como barrera cervical, en presencia de coágulo sanguíneo como...

Recovery of motor function in rats with complete spinal cord injury following implantation of collagen/silk fibroin scaffold combined with human umbilical cord-mesenchymal stem cells

SUMMARY OBJECTIVE: This study aimed to assess the effect of the collagen/silk fibroin scaffolds seeded with human umbilical cord-mesenchymal stem cells on functional recovery after acute complete spinal cord injury. METHODS: The fibroin and collagen were mixed (mass ratio, 3:7), and the composite scaff...

Comparison of two different biomaterials in the bone regeneration (15, 30 and 60 days) of critical defects in rats

Acta cir. bras; 36 (6), 2021
ABSTRACT Purpose To evaluate and compare two types of different scaffolds in critical bone defects in rats. Methods Seventy male Wistar rats (280 ± 20 grams) divided into three groups: control group (CG), untreated animals; biomaterial group 1 (BG1), animals that received the scaffold implanted hydrox...

Quantification of adhesion of mesenchymal stem cells spread on decellularized vein scaffold

Acta cir. bras; 36 (10), 2021
ABSTRACT Purpose: To evaluate methods that improve adipose-derived stem cells (ASCs) population in decellularized biological venous scaffold for tissue engineering in blood vessels, a model in rabbits. Methods: The ASC was expanded until the third passage. Inferior vena cava (IVC) was submitted to the ...
