Introduction: The pineal gland represents a neuroendocrine organ. Gland parenchyma is composed of higher percentage of pinealocytes and about 5% of glial cells. Earlier studies showed that there is reduced cellularity of gland, gliosis and higher percentage of calcification during aging in addition to increased accumulation of pigments in pinealocytes.
Aim: Aim of this study was to monitor the expression of marker S-100β in tissue of human pineal gland, as well as identification of differences in expression of the same marker depending on the sex and according to age.
Material and Methods: The study included 26 samples which were divided into two groups: group I (n=13) included the pineal glands of people younger than 50 years and group II (n=13) pineal glands of people older than 50 years. After histological processing of samples, sections were stained with hematoxylin-eosin stain and immunohistochemically with anti - S-100β antibody. The number of glial cells of the pineal gland was determined, also with the total number of cells per unit area. In data processing we used Mann-Whitney test and statistically significant value was considered p<0,05.
Results: There was an increased total number of cells per unit area in people younger than 50 years. Percentage of glial cells was increased in people older than 50 years.
Conclusion: The glial cells of the human pineal gland showed S-100β positive staining. During aging the percentage of human glial cells was increased, while pineal parenchyma in younger people was more cellular.
