Abstract

Hair is one of the smallest organs, but has many important functions to mammals. Hair morphogenesis occurs through the reciprocal exchange of epithelial and mesenchymal signals. There are some reports about the expression of laminin-511 and -332 during hair morphogenesis, but are no reports of the chronological expression and function of laminin-511 and its counter regulator laminin-332 during hair morphogenesis. Our results of immunoblotting revealed that laminin-332 proteins were detected at stage 0 and downregulated during stage 1 to stage 2, and then recovered at stage 3. However, laminin α5 expression was constant throughout stages 0-3. According to the results of semi-quantitative RT-PCR, the mRNA expression of all laminin-332 subunits increased gradually from stage 0 to stage 2, while the mRNA expression of all laminin-511 subunits remained constant from stage 0 to stage 3. Our results suggest that the proper expression of laminin-332 and laminin-511 may regulate appropriate hair morphogenesis.
