Advances in Zebrafish as a Comprehensive Model of Mental Disorders

Figure 4

The nanoparticles injected into the zebrafish pass through the blood and are deposited around the cerebral blood vessels. Diblocks of the polymeric material PEG-b-PLA were created through the process of ring opening polymerisation, utilizing either PEG2000 (A, B) or PEG5000 (C, D). After imaging, the caudal vascular plexus (CVP), posterior common vein (CCV), dorsal artery (DA), and posterior cardinal vein (PCV) can be seen clearly. The blue arrow represents venous blood vessels, and the red arrow represents arterial blood vessels. Reproduced with permission from [112].
