Cell-matrix's Response to Mechanical Forces01:13

Cell-matrix's Response to Mechanical Forces

2.7K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue. 
Anchoring junctions mechanically attach a cell to the...

Somatic to iPS Cell Reprogramming

2.3K
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...

Regulation of Metabolism01:19

Regulation of Metabolism

9.6K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Cells Coordinate Growth and Proliferation02:36

Cells Coordinate Growth and Proliferation

4.6K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

Mechanical Protein Functions01:58

Mechanical Protein Functions

5.0K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Methods of Nuclear Reprogramming01:24

Methods of Nuclear Reprogramming

1.9K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

Summary
This summary is machine-generated.

Cells sense mechanical forces through identified receptors and internal transmission mechanisms. However, how cells integrate this mechanical information with other cellular events remains largely unexplored.

Area of Science:

  • Cell biology
  • Mechanobiology
  • Biophysics

Background:

  • Cells are known to sense and respond to mechanical forces.
  • The receptors and force transmission mechanisms involved in mechanotransduction are increasingly understood.
  • However, the integration of mechanical signals with other cellular processes is not well understood.

Purpose of the Study:

  • To review the mechanisms of mechanotransduction at cell-cell and cell-matrix adhesions.
  • To summarize how cells integrate mechanical information from adhesion complexes with cellular metabolism.

Main Methods:

  • Literature review of mechanotransduction mechanisms.
  • Synthesis of current understanding of signal integration.

Main Results:

  • Mechanisms of force sensing and transmission at cell adhesions are identified.
  • Integration of adhesion-based mechanical signals with cellular metabolism is a key area for future research.

Conclusions:

  • While the sensing and transmission of mechanical forces by cells are well-studied, the integration of this information with other cellular events, particularly metabolism, requires further investigation.
