Differences between retractosomes and migrasomes

Property	Retractosome	Migrasome
Diameter	∼50–250 nm	∼500–3,000 nm
Morphology	String of beads–like	Opened pomegranate–like
Biogenesis	Minutes Along the broken-off RFs Cholesterol-independent	Hours At the junctions or tips of RFs Cholesterol-dependent
Cargoes	Lack any identifiable internal structures	Small vesicles Damaged mitochondria mRNA, etc.
Functions	Unknown	Delivery of signaling molecules Maintaining cellular homeostasis Lateral transfer of materials, etc.
