TLDR Researchers used a laser to create advanced skin models with hair-like structures.
The study demonstrated that microscopy-guided laser ablation (MGLA) could create complex skin models with folliculoid appendages by forming 3D microchannels in fibroblast-laden hydrogels. These channels facilitated the interaction of keratinocytes (KCs) and dermal papilla (DP) cells, leading to the formation of follicular-like structures. Despite some cell death near the ablation sites, overall cell viability was maintained, and the resulting structures exhibited complex epithelial organization and marker expression similar to human hair follicles. This advanced biofabrication technique provided a sophisticated in vitro model for studying hair follicle development and could be useful for cosmetic testing and drug development.
