Cell Motility through Blebbing01:16

Cell Motility through Blebbing

1.9K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

Metastasis02:30

Metastasis

5.4K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Cell Migration01:09

Cell Migration

16.6K
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.

Cell Migration01:19

Cell Migration

6.1K
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.

Fibronectins Connect Cells with ECM01:25

Fibronectins Connect Cells with ECM

2.9K
Fibronectin is an adhesive glycoprotein present in the extracellular matrix of embryogenic and adult tissue. These molecules primarily aid in regulating cell motility and attachment. A fibronectin molecule is composed of two identical polypeptide chains attached to each other by a pair of disulfide bonds at the C-terminal.
Both proteoglycans and collagen are attached to fibronectin proteins, which, in turn, are attached to integrin proteins. These integrin proteins interact with transmembrane...

IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

12.5K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the  phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

Summary

Lignin forms precise bands in root endodermal cells, creating the Casparian strip. This structure is vital for controlling water and solute movement into the plant vascular system.

Area of Science:

  • Plant biology
  • Cell biology
  • Biochemistry

Background:

  • Lignin deposition patterns are crucial for plant cell function.
  • The Casparian strip in the root endodermis is a key structure for regulating water and solute transport.
  • Understanding lignin patterning is essential for plant physiology.

Purpose of the Study:

  • To investigate the mechanisms underlying the precise spatial deposition of lignin in the Casparian strip.
  • To elucidate how specific cellular patterns of lignin are established in the root endodermis.

Main Methods:

  • Analysis of lignin deposition patterns using advanced microscopy techniques.
  • Investigating the molecular players involved in guiding lignin localization.
  • Comparative studies across different plant species or mutants.
