Wool growth and fineness regulation is influenced by some factors such as genetics and environment. At the same time, lncRNA participates in numerous biological processes in animal production. In this research, we conducted a thorough analysis and characterization of the microstructure of wool, along with long non-coding RNAs (lncRNAs), their target genes, associated pathways, and Gene Ontology terms pertinent to the wool fineness development.

Decorin (DCN) is a member of the small leucine-rich proteoglycan family within the extracellular matrix, playing a role in the growth and development of hair follicle (HF). Exosomes serve as significant mediators of intercellular communication and are involved in the cyclic regeneration of HF. Exosomes derived from dermal papilla cells (DPC-Exos) are essential for the cycling and regrowth of HF.

In the high altitudes of the Andes, llama breeders shear the fiber from their animals, obtaining fleeces for many purposes. Dehairing the fleece of these animals is a viable alternative to improving the quality and value of the fleece. The study examined the attributes of fiber quality and pilose follicle of dehaired and non-dehaired fleece from Ch'aku llamas and the relationship among these characteristics.

Wool quality is a crucial economic trait in Angora rabbits, closely linked to hair follicle (HF) growth and development. Therefore, understanding the molecular mechanisms of key genes regulating HF growth and wool fiber formation is essential. In the study, fine- and coarse-wool groups were identified based on HF morphological characteristics of Zhexi Angora rabbits.

Dorper sheep is popular among farming enterprises with strong adaptability, disease resistance, and roughage tolerance, and an unique characteristic of natural shedding of wool. In a large number of observations on experimental sheep farms, it was found that the wool of some sheep still had not shed after May, thus manual shearing was required. Therefore, understanding the molecular mechanisms of normal hair follicles (HFs) development is crucial to revealing the improvement of sheep wool-related traits and mammalian skin-related traits.
