Induced Pluripotent Stem Cells

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore called induced pluripotent stem...

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Somatic to iPS Cell Reprogramming

Somatic to iPS Cell Reprogramming

Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012 for this...

iPS Cell Differentiation

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Storage

Storage

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze each...

Sus antecedentes:

Las plataformas de cultivo celular (CCP, por sus siglas en inglés) son cruciales para estudiar el efecto de la estimulación mecánica en el destino celular.
Los CCP tradicionales son complejos, costosos y voluminosos debido a los sistemas electromecánicos integrados.

Objetivo del estudio:

Desarrollar un CCP simplificado, miniaturizado y rentable utilizando propiedades de materiales inteligentes.
Para demostrar un nuevo paradigma de accionamiento para la estimulación celular mecánica.

Principales métodos:

Una novela es una novela.
El material como máquina.
Se diseñó la plataforma de cultivo celular inteligente (MM-SCCP).
El polinorborneno de memoria de forma (PNB) se utilizó como área de accionamiento (AA) para reemplazar los sistemas tradicionales.
La recuperación de la forma de PNB a 37 °C generó tensión para activar el área de cultivo celular (CA), aplicando tensión de tracción.

Principales resultados:

El AA basado en PNB demostró excelentes propiedades mecánicas (módulo: 1038.2 MPa) y rendimiento de memoria de forma (fijidad: 99.6%, recuperación: 99.2%).
Se aplicó con éxito una tensión de tracción controlable a sustratos de polímeros comunes (PDMS, poliuretano).
La cepa aplicada regulaba efectivamente la orientación de las células y la relación de aspecto, validando la viabilidad de la plataforma.

Conclusiones:

El MM-SCCP ofrece un enfoque innovador para la inteligencia, la miniaturización y la reducción del costo de las ECC.
Este paradigma de accionamiento basado en PNB presenta un método versátil para la estimulación mecánica celular en investigación y desarrollo.
