Resumen

Las células madre mesenquimales (MSC) en un nuevo hidrogel HA-GLC promueven la regeneración del cartílago para la osteoartritis. Esta tecnología mejora la función de las MSC al proporcionar glucosa, mejorar la proliferación de condrocitos y reducir la inflamación.

Área de la Ciencia:

Medicina Regenerativa; Ciencia de Biomateriales; Biología Celular

Sus antecedentes:

La terapia con células madre mesenquimales (MSC) es prometedora para el tratamiento de la osteoartritis (OA) a través de la señalización paracrina.; El entorno articular avascular limita la supervivencia y la eficacia terapéutica de las MSC debido a la privación de nutrientes.; Se desarrolló un novedoso hidrogel de ácido hialurónico y glucosa (HA-GLC) para mantener las MSC en condiciones de baja glucosa.

Objetivo del estudio:

Investigar el impacto del hidrogel HA-GLC en la supervivencia y el secretoma de MSC.; Evaluar cómo la disponibilidad de glucosa influye en la composición y función del secretoma de MSC.; Evaluar el potencial terapéutico del secretoma de MSC cultivadas en hidrogel HA-GLC en condrocitos humanos.

Principales métodos:

Incorporación de MSC en el hidrogel HA-GLC.; Análisis proteómico del secretoma de MSC en diversas condiciones de glucosa.; Evaluación de la proliferación de condrocitos humanos (hCH) y la secreción de IL-6 en respuesta al secretoma de MSC.

Principales resultados:

El hidrogel HA-GLC soporta la supervivencia y proliferación de MSC en entornos de baja glucosa.; La privación de glucosa altera el secretoma de MSC, afectando las vías de producción de matriz extracelular.; El secretoma de MSC de condiciones con suministro de glucosa mejoró la proliferación de hCH y redujo significativamente la expresión de IL-6.

Conclusiones:

El hidrogel HA-GLC modula eficazmente la función del secretoma de MSC al controlar la disponibilidad de glucosa.; Esta tecnología muestra potencial para mejorar la regeneración del cartílago en la OA al optimizar la actividad paracrina de las MSC.; El suministro de glucosa dirigido a través de hidrogeles HA-GLC representa una estrategia prometedora para terapias basadas en MSC.

Glucose Homeostasis: Regulation of Blood Glucose

Glucose Homeostasis: Regulation of Blood Glucose

Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

Glucose Transporters

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Glucose Absorption Into the Small Intestine

Glucose Absorption Into the Small Intestine

Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and...

Hormones Regulating Blood Glucose

Hormones Regulating Blood Glucose

Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

Paracrine Signaling

Paracrine Signaling

Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. Such a signal can only trigger a response in nearby target cells because the signal molecules degrade quickly or are inactivated if not taken up. Prominent examples of paracrine signaling include nitric oxide signaling in blood vessels, synaptic signaling of neurons, the blood clotting system, tissue repair/wound healing, and local allergic skin reactions. Nitric oxide as a...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are...
