Resumen
El establecimiento de la polaridad celular planar (PCP) está relacionado con las fuerzas mecánicas durante el desarrollo embrionario. Esta revisión explora cómo las tensiones mecánicas influyen en la PCP y cómo la señalización de la PCP regula las fuerzas tisulares para una morfogénesis adecuada.
Área de la Ciencia:
- Biología del Desarrollo
- Biología Celular
- Biofísica
Sus antecedentes:
- Las fuerzas mecánicas son señales cruciales en el desarrollo embrionario.
- La polaridad celular planar (PCP) es esencial para la morfogénesis epitelial.
- La interacción entre la PCP y la señalización mecánica no se comprende completamente.
Objetivo del estudio:
- Revisar la evidencia que vincula la PCP y la mecanotransducción.
- Explorar cómo las tensiones mecánicas establecen la PCP.
- Investigar el papel de la señalización de la PCP en la mecánica de los tejidos.
Principales métodos:
- Revisión de literatura de investigaciones existentes.
- Análisis de datos sobre el establecimiento de la PCP y la mecanotransducción.
- Hipótesis de un bucle regulador entre la PCP y las fuerzas mecánicas.
Principales resultados:
- La PCP se puede establecer en respuesta a tensiones mecánicas.
- La señalización de la PCP influye en la generación de fuerzas físicas en los tejidos.
- Un bucle de retroalimentación positiva conecta la PCP y la mecanotransducción.

01:31Mechanism of Lamellipodia Formation
3.5K
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...

01:32Cytoskeletal Coordination in Cell Migration
5.4K
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...

01:21Cell Polarization by Rho Proteins
3.5K
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...

01:39Mechanism of Filopodia Formation
3.0K
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

18.5K
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

01:19Cell Migration
6.3K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.
