ABSTRACT
INTRODUCTION:
Geminin, a (25 kDa) protein, was originally identified as a key regulator of DNA replication licensing in the cell cycle and of cell fate during embryonic nervous system formation. Although geminin is involved in mechanisms underlying the regulation of transcription and patterning in embryonic development, its expression and possible significance in human epidermal morphogenesis remains unknown.METHODS:
Forty-one skin biopsy specimens obtained from human fetuses (10th to 23rd week of estimated gestational age) were processed for immunohistochemistry using a primary rabbit polyclonal antibody against geminin.RESULTS:
Distinct and statistically significant qualitative and quantitative alterations in the spatiotemporal expression pattern of geminin were observed in the developing human epidermis.CONCLUSIONS:
The highly ordered expression of geminin in different layers of fetal human epidermis reported here for the first time suggests that this protein may play a significant role in epidermal morphogenesis. However, the mechanisms underlying the alterations of the geminin expression pattern during fetal development at the molecular level remain to be elucidated. Further studies are now warranted to address whether the expression pattern of geminin in the developing human epidermis is disturbed in fetuses with genodermatoses and whether these disturbances might be important for prenatal diagnosis of genodermatoses.
