This video demonstrates the coculturing model of a dorsal root ganglion explant and Schwann cells. In coculture conditions, ascorbic acid promotes the differentiation of Schwann cells into myelinating forms. Myelinating Schwann cells wrap the axons multiple times to create a myelin sheath, which is essential for nerve function.

This protocol presents the use of a dorsal root ganglion (DRG) injection with a viral vector and a concurrent dorsal root crush injury in an adult rat as a model to study sensory axon regeneration. This model is suitable for investigating the use of gene therapy to promote sensory axon regeneration.
FAQs
The three layers contribute to sheath specialization in different ways: the cuticle, Huxley’s layer, and Henle’s layer contain cells that produce hard keratins and trichohyalin. As these cells move upward, their programmed keratinization increases structural rigidity. This coordinated composition gives the developing hair shaft a controlled cellular environment for differentiation and orderly growth.
Upward movement couples cell maturation to the changing structure of the follicle. As inner root sheath cells undergo programmed keratinization, they become part of a rigid guide around the developing shaft. This guidance supports orderly hair-shaft differentiation and helps preserve follicle architecture during the growth process.
The sheath’s breakdown near the follicle’s upper region marks a change in its role over the follicle’s length. It provides structural guidance while the hair shaft develops, then is no longer maintained as the shaft advances upward. This spatial transition helps explain how support and follicle architecture are organized in distinct regions.
Examining the inner root sheath connects cellular keratinization with visible hair formation. Researchers can consider how the cuticle, Huxley’s layer, and Henle’s layer contribute to shaft shaping, how upward cell movement changes sheath rigidity, and how breakdown occurs near the upper follicle. These observations support analysis of follicle biology and hair-growth organization.
Because the sheath helps organize shaft differentiation and follicle architecture, its biology provides a cellular context for hair-disorder research. Investigating hard-keratin and trichohyalin production, upward maturation, and regional breakdown gives researchers specific features to examine when relating follicle structure and hair-shaft formation to disorder-focused studies.
In tissue-engineered skin, knowledge of the inner root sheath provides a biological reference for recreating relationships that support hair-shaft differentiation and follicle architecture. Its layered organization, hard-keratin and trichohyalin production, upward maturation, and eventual upper-region breakdown identify features that models can investigate when studying follicle regeneration and skin construction.
