The study by G. E. Rogers uses electron microscopy to explore the fine structural organization of a-keratins in hair and wool, identifying microfibrils as fundamental units within a sulfur-rich matrix. It highlights the effectiveness of OsO4 staining in enhancing visibility and notes structural differences in various hair and wool types, correlating microfibril clarity with cystine content. Merino wool shows distinct orthocortex and paracortex regions, with the paracortex having higher cystine content, affecting dye penetration. Human hair lacks bilateral structure but contains both microfibrillar packing types. The research provides detailed insights into the complex microscopic structure and composition of hair and wool fibers.
