Summary
Estrogen receptor (ER)-alpha is present in human dental pulp cells, including odontoblasts and endothelial cells. This finding confirms ER-alpha expression in the pulp, with higher reactivity observed in female Schwann cells.
Area of Science:
- Endocrinology
- Cell Biology
- Dental Research
Background:
- Estrogen receptors (ERs) play crucial roles in various physiological processes.
- The presence and function of ERs in human dental pulp are not fully understood.
Purpose of the Study:
- To investigate the expression and localization of estrogen receptor (ER)-alpha in human dental pulp tissue.
- To determine if ER-alpha expression varies with age or sex.
Main Methods:
- Human dental pulp samples were obtained from 51 teeth.
- Immunohistochemical staining using a specific anti-ER-alpha antibody was performed.
- Reactivity was semiquantitatively assessed on a scale of 0 to 3.
Main Results:
- ER-alpha was detected in odontoblasts, endothelial cells, and Schwann cells.
- ER-alpha expression was common in odontoblasts and endothelial cells.
- Higher ER-alpha reactivity was observed in Schwann cells of female pulps, with no significant differences noted across age groups.
Conclusions:
- This study confirms the expression of ER-alpha in human dental pulp.
- ER-alpha is present in key dental pulp cell types, suggesting potential roles in pulp physiology.
- Sex-specific differences in ER-alpha expression in Schwann cells warrant further investigation.
