Figure 6.

Cytotoxicity assay measured viability (%) of SHEDs in response to aliquots at day 1, 3, 7, 14, 21, and 28 from GelMA-based hydrogels modified or not with 1, 2, and 5% of halloysite nanotubes (H) and CHX-loaded nanotubes (H-C10% and H-C20%). Statistical analyses were compared with the same day. The percentage of cell viability was normalized by the mean absorbance of SHEDs cultured in the plate at day 1 (100%). Distinct letters indicate statistically significant differences between the groups when compared with the control (SHED cells). The results are presented as mean ± SD (n = 5).
