TLDR Wool follicles are complex, involving interactions between different cell types and structures.
The study of wool and hair follicles revealed that the basement membrane, which is slightly periodic acid/schiff-positive and contains highly sulfated glycosaminoglycans, is surrounded by a connective-tissue sheath. The complexity of the follicle, particularly the interactions between dermal and epithelial components and various cell lines during differentiation, was well established. Early cytological and cytochemical studies indicated multiple levels of complexity, suggesting that many processes previously explained mechanistically have a cytological basis. The significance of these studies would be better understood when related to specific cell components, highlighting the importance of cytological techniques in future research.
