Total distance traveled in the darkness of <120 hpf zebrafish larvae after 48 h of incubation with selected extracts obtained from curdlan-based biomaterials enriched with CE or XN (a). No significance was found between tested groups, one-way ANOVA test followed by Tukey’s multiple comparisons, p > 0.05. Scheme of caudal fin amputation of 70 hpf larval zebrafish, and the post-amputation regrowth assessment after 48 h of incubation with selected extracts obtained from curdlan-based biomaterials enriched with CE or XN, a—length from the end point of the tail to the cut line, b—length from the end point of the tail to the end point of the the caudal fin regeneration after 48 h post amputation (b), created with BioRender.com. Caudal fin regrowth data are presented as normalized (%) to control E3 (c). ^# Significantly different results compared to results obtained for control E3; one-way ANOVA test followed by Tukey’s multiple comparisons, p < 0.05. Examples of stereoscopic microscope images showing regeneration of zebrafish larvae caudal fins after 48 h post-amputation (48 hpa) (d).
