TLDR The new biomaterial helps grow blood vessels and hair for skin repair.

The study presents a novel 3D multicellular micropatterning approach for hair regeneration and vascularization using bioprinting technology. By arranging hair follicle-related cells within vascular-cell networks and incorporating magnesium silicate (MS) nanomaterials, the researchers created a biomimetic micropattern with significant follicular and angiogenic potential. This 3D micropattern demonstrated efficient hair regrowth in both immunodeficient and androgenetic alopecia (AGA) mice models, suggesting its potential for effective skin tissue regeneration and hair follicle function recovery.
