Hair follicle stem cells (HFSCs) play critical roles in the periodic regeneration of hair follicles. HFSCs are also a good model for stem cell biology research. However, no stable mouse HFSC cell line has been reported, which restricts the research and application of HFSCs. We isolated HFSCs from mouse hair follicles and immortalized them by inducing a reversible SV40 large T antigen. Through monoclonal screening, we identified a reversibly immortalized cell line, immortalized HFSC (iHFSC2). RNA sequencing, fluorescence-activated cell sorting, western blotting and immunofluorescence experiments revealed that the expression patterns of iHFSC2 and HFSC were similar at the protein and mRNA levels. After that, iHFSC2s were passaged and morphologically monitored for up to 40 times to detect their long-term culture potential. The long-term cultured iHFSC2 could regenerate hair follicles with complete hair follicle structure and HFSCs in the bulge area. This work successfully established an HFSC cell line with the ability of hair follicle reconstruction.

Skin regeneration, repair, and the promotion of hair growth are intricate and dynamic processes essential for preserving the overall health, functionality, and appearance of both skin and hair. These processes involve a coordinated interplay of cellular activities and molecular signaling pathways that ensure the maintenance and restoration of skin integrity and hair vitality. Recent advancements in regenerative medicine have underscored the significant role of mesenchymal stem cell (MSC)-derived exosomes as key mediators in these processes.

The ability to grow long scalp hair is a distinct human characteristic. It probably originally evolved to aid in cooling the sun-exposed head, although the genetic determinants of long hair are largely unknown. Despite ancestral variations in hair growth, long scalp hair is common to all extant human populations, which suggests its emergence before or concurrently with the emergence of anatomically modern humans (AMHs), approximately 300 000 years ago.

As a widely epigenetic modification, mA (N-methyladenosine, mA) can regulate the degradation, translation, and other biological functions of circRNAs through dynamic reversible processes. It plays an important role in regulating the life activities of biological organisms, particularly in cell differentiation, apoptosis, embryonic development, stress response, and innate immunity. In this study, bioinformatics analysis, qRT-PCR identification, FISH subcellular localization, and ceRNA network construction were performed on mA modified circRNAs regulating the apoptosis of secondary hair follicle cells of Inner Mongolia Albas white cashmere goats based on the skin mA sequencing data of secondary hair follicles in anagen and catagen.
