Myosin and Actin in Hair Follicle 121 Fig. 6. Co-localization of non-muscle myosin and actin in special hair matrix cells. Immunofluorescence staining. Panel A–D and panel E–H are the results obtained from a single section. Samples were stained for non-muscle myosin (red) (A, E) and actin (green) (B, F). Merged images are shown in C and G. Nuclei were stained with DAPI (blue). Corresponding Nomarski images are also shown (D, H). Bars50 m. this might be the reason why the accumulation of myosin and actin was not observed in most cells of the dermal papil- lae. 6) Actively dividing cells in the basal layer of skin epi- dermis as well as those in the hair matrix seem to have mea- ger amounts of actin and myosin. Although these proteins are components of the contractile ring, their quantities may be insignificant in comparison to those associated with the cytoskeleton and cortical skeletal structures.
