Acid Phosphatase Distribution in the Wool Follicle: Fate of Organelles in Keratinized Cells

The study from 1976 investigated the presence and fate of cell organelles in keratinized cells of the Romney wool follicle. It was found that recognizable organelles, such as lysosomes, mitochondria, gap junction-bounded vesicles, and vacuolar-like organelles, persisted in both the keratinized fiber and the hardened inner root sheath. In the cortex, single membrane-bounded bodies and vesicles were detected in cytoplasmic remnants, resembling the lysosomes of the differentiating cortex. The fiber cuticle contained fewer single membrane-bounded organelles in the endocuticle compared to the cortex.
