Blast cells

Blood cells in early stage of cellular development.


1. an immature stage in cellular development before appearance of the definitive characteristics of the cell; used also as a word termination, as in ameloblast, etc.
2. the wave of air pressure produced by the detonation of high-explosive bombs or shells or by other explosions; it causes pulmonary damage and hemorrhage (lung blast, blast chest), laceration of other thoracic and abdominal viscera, ruptured eardrums, and effects in the central nervous system.
