The paper introduces 3D DNase-Enhanced Expression Profiling (3DEEP), a novel spatial transcriptomics method designed to map the complex development of organs in four dimensions. By removing genomic DNA and clearing tissue, researchers captured hundreds of developing hair follicles within thick sections of neonatal mouse skin, effectively preserving their intricate three-dimensional structures. The study utilizes a "spatial snapshot" to order these follicles by molecular age, creating a comprehensive timeline of organogenesis that identifies three distinct stages of maturation. This 4D…
