TLDR Mouse hair follicle stem cells were successfully isolated and used to regenerate hair follicles with two different methods.
The document from 2016 detailed a method for isolating hair follicle bulge stem cells (HFSCs) from mice and evaluating their ability to regenerate hair follicles using two different assays: the patch assay and the silicone chamber assay. The HFSCs were shown to be capable of regenerating de novo hair follicles and repopulating all cell lineages within these follicles. The patch assay was described as easier and more cost-effective, but with limitations such as uncontrolled hair shaft orientation and improper hair cycling. In contrast, the chamber assay, though more labor-intensive, resulted in correctly oriented hairs with normal cycling. The study provided protocols for isolating HFSCs, performing cell sorting, and preparing cells for reconstitution assays, highlighting the potential of HFSCs in regenerative medicine. However, the document did not specify the number of mice used or the success rates of the assays.
