Intraarticular Administration of Dexamethasone after Mesenchymal Stem Cells Implantation Does Not Improve Significantly the Treatment of Preestablished Full-Thickness Chondral Defect in a Rabbit Model

Objective: The aim of this study was to evaluate the contribution to hyaline cartilage regeneration of dexamethasone intraarticular administration after autologous mesenchymal stem cells (MSCs) implantation into a preestablished knee full-thickness chondral defect. Design: Full-thickness chondral defects of 4.5 × 4.5 mm2 were surgically made in both medial femoral condyles of adult male New Zealand rabbits. Two weeks later, autologous ex vivo expanded bone marrow–derived MSCs were embedded in hyaluronic acid and implanted into the chondral defects. Immediately and every week after the intervention, dexamethasone 0.25 mg/kg was intraarticularly administered (MSC/dexa-treated group). Six weeks after MSC transplantation, the animals were euthanized and condyles were characterized molecularly according to aggrecan, collagen type II, and collagen type I gene expression (quantitative reverse transcriptase-polymerase chain reaction) and histologically (hematoxylin–eosin staining). Data of MSC/dexa-treated condyles were compared with untreated, dexa-treated, MSC-treated, or normal unlesioned condyles. Results: The ratio between collagen type II expression versus collagen type I expression in MSC/dexa-treated condyles was higher than one, even though the group mean value was not statistically different from that of untreated defects. Histological changes were observed between MSC/dexa-treated and untreated defects mainly in surface regularity and in hyaline matrix abundance. However, International Cartilage Repair Society score analysis did not support robust differences between those groups. Conclusion: Intraarticular administration of dexamethasone after autologous MSC implantation into a preestablished full-thickness chondral defect does not contribute significantly to the regeneration of a tissue with molecular and histological characteristics identical to hyaline cartilage.

Dynamic of distribution of human bone marrow-derived mesenchymal stem cells after transplantation into adult unconditioned mice

Background. The use of mesenchymal stem cells (MSC) for cell therapy relies on their capacity to engraft and survive long term in the appropriate target tissue(s). Animal models have demonstrated that the syngeneic or xenogeneic transplantation of MSC results in donor engraftment into the bone marrow and other tissues of conditioned recipients. However, there are no reliable data showing the fate of human MSC infused into conditioned or unconditioned adult recipients. Methods. In the present study, the authors investigated, by using imaging, polymerase chain reaction (PCR), and in situ hybridization, the biodistribution of human bone marrow-derived MSC after intravenous infusion into unconditioned adult nude mice. Results. As assessed by imaging (gamma camera), PCR, and in situ hybridization analysis, the authors' results demonstrate the presence of human MSC in bone marrow, spleen, and mesenchymal tissues of recipient mice. Conclusions. These results suggest that human MSC transplantation into unconditioned recipients represents an option for providing cellular therapy and avoids the complications associated with drugs or radiation conditioning.

Diseño y validación de un cuestionario para evaluar oportunidades de práctica pedagógica, metacognición y «lifelong learning», brindadas por los programas de formación inicial docente

2021 , Kiomi Matsumoto-Royo , María-Soledad Ramírez-Montoya , CONGET MOLINA, PAULETTE ANDREA

El objetivo del estudio fue diseñar y validar un cuestionario para recoger información respecto de las oportunidades que brindan los programas de formación inicial docente de aproximarse a la práctica pedagógica, de desarrollar habilidades de procesamiento metacognitivo y de adoptar el lifelong learning. El instrumento fue diseñado conforme a la literatura y validado usando el método Delphi. Fue aplicado en una muestra de 198 estudiantes de Pedagogía. Luego de ajustes en función de los resultados de un análisis factorial confirmatorio, se obtuvo una versión de alta validez y confiabilidad. El cuestionario está organizado en tres dimensiones y 24 reactivos y permite estudiar desde la perspectiva de los estudiantes las acciones de los programas de formación docente, constituyendo un marco referencial para orientar las decisiones de ajuste e innovación en este ámbito de formación.
