cav·i·ta·tion

 (kăv′ĭ-tā′shən)
n.
1. The sudden formation and collapse of low-pressure bubbles in liquids by means of mechanical forces, such as those resulting from rotation of a marine propeller.
2. The pitting of a solid surface.
3. Medicine The formation of cavities in a body tissue or an organ, especially those formed in the lung as a result of tuberculosis.

[From cavity.]

To date, there have been no serious adverse events related to the AST-OPC1 cells.Cell Engraftment - 92% of Cohort 3 and 4 subjects have magnetic resonance imaging (MRI) scans at twelve months consistent with the formation of a tissue matrix at the injury site, which is encouraging evidence that AST-OPC1 cells have engrafted at the injury site and helped to prevent cavitation. The 12-month MRI results-to-date for 94% of the Cohort 2-4 subjects provide supportive evidence that AST-OPC1 cells have durably engrafted at the injury site and helped to prevent cavitation.
