research The high-polarity fraction of tail fat derived from Lanzhou Fat-Tailed sheep enhances skin wound healing through the regulation of inflammatory factors and the TGF-β1/Smad3 signaling pathway
The study investigated the effects of the high-polarity fraction (HPF) of tail fat from Lanzhou Fat-Tailed sheep on skin wound healing in mice. The HPF demonstrated significant antioxidant activity and improved wound healing outcomes compared to other fractions and a non-treated group. It reduced pro-inflammatory cytokines IL-1β and TNF-α, increased TGF-β1 levels, and promoted collagen production and remodeling, which are crucial for preventing scar formation. Additionally, HPF enhanced the development of hair follicles and sebaceous glands. Molecular analyses showed that HPF upregulated TGF-β1 and downregulated Smad3, contributing to its wound healing efficacy.
research Deciphering the cellular landscape and genetic underpinnings of fiber diameter determined by dermal papilla cells in fine-wool sheep
This study used single-cell RNA sequencing on skin tissues from six fine-wool sheep to explore the molecular mechanisms regulating hair follicle development and fiber diameter. A transcriptional atlas of the hair follicle microenvironment was constructed, identifying 14 distinct cell types and revealing that the ultra-fine wool group had a higher proportion of dermal papilla cells (DPCs), hair follicle stem cells, and outer root sheath cells. The study highlighted the role of DPCs in hair follicle growth, identifying three distinct states of DPCs and analyzing differentially expressed genes, such as CRABP1, which influences DPC proliferation. These findings provide insights into hair follicle biology and potential molecular targets for breeding ultra-fine wool sheep.
