Cell anatomy

The division of a mitochondrion within a cell to form two or more separate mitochondrial compartments.

type of chromosome

interior space of the plasma membrane

group of proteins that form junctions between organelles, facilitating lipid transfer from the ER to other organelles via non-vesicular transport

Macropinosomes are a type of cellular compartment that form as a result of macropinocytosis.

Invadopodia are actin-rich protrusions of the plasma membrane that are associated with degradation of the extracellular matrix in cancer invasiveness and metastasis. Very similar to podosomes, invadopodia are found in invasive cancer cells and are important for their ability to invade through the extracellular matrix, especially in cancer cell extravasation. Invadopodia are generally visualized by the holes they create in ECM (fibronectin, collagen etc.)-coated plates, in combination with immunohistochemistry for the invadopodia l
