Corrigendum to '3D Bioprinting of a Gelatin-Alginate Hydrogel for Tissue-Engineered Hair Follicle Regeneration'

The document is a corrigendum to a previous study on 3D bioprinting of a gelatin-alginate hydrogel for tissue-engineered hair follicle regeneration. The authors made several corrections to the original paper, including replacing the bioprinter nozzle image in the Graphical Abstract, removing the text "(n = 6)" from the Materials and Methods section, and adding in-vitro pictures of reconstructed hair follicle-like structures in 3D-bioprinted multilayer composite scaffolds. They also replaced several poorly performed images in Figure 8. Despite these corrections, the authors affirm that the findings and conclusions of the work remain unchanged. The study involved the use of a 3D-bioprinted multilayer composite scaffold to facilitate hair follicle regeneration in vivo, with substantial hair growth observed in both the 3D-bioprinted scaffold and traditional chamber assay groups.
