FIGURE 1.
The organization and distributions of migrasomes. Migrasome, which is an extracellular membrane-bound vesicular structure and includes cytosolic proteins and small vesicles in the cavity, is organized by TSPANs, cholesterol, and integrins. The matching of specific integrin-ECM pairs determine when and where migrasome can be generated in vivo. They are distributed in human blood and stroke specimens; in mouse brain and eye, rat lung, rat/mouse intestine; in zebrafish embryo. They are also found in numerous cancer cells, such as MDA-MB-231, SKOV-3, HCT116, SW480, MGC803, B16; in normal rat or mouse cells, including NRK, NIH3T3, mouse embryonic stem cells, hippocampal neurons and bone marrow-derived macrophages, and microglia; and in HaCaT in vitro.
