Thus, bulge stem cells are multipotent and can give rise to epidermis, hairfollicle and sebaceous gland lineages. These data clearly demonstrate that cells within the hairfollicle bulge possess the classical defining features of bona fide stem cells. The inset diagram shows the migration of a multipotent progenitor cell along the hairfollicle fate lineage. In particular, mobilisation of epithelial stem cells out of the hairfollicle upon mitogen-induced proliferation is more affected when telomeres are critically short. An important structure of the hairfollicle is the bulge, which is where the hair folllicle stem cells have been shown to reside. The initial inflammation event increases hairfollicle dystrophy and promotes continued pathogenic cell recruitment to perpetuate the autoimmune disease cycle. During this complex developmental process, the outer embryonic ectoderm and its underlying mesoderm give rise to the epidermal and dermal components, which essentially build up the hairfollicle unit. A possible therapeutic strategy might therefore be to replace or reinforce immune privilege through the promoting of immune-protective cytokines and cell ligands, which might reduce hairfollicle antigen exposure. Thus, hairfollicle stem cells provide an effective, accessible, autologous source of stem cells for treatment of peripheral nerve injury.
