Multinucleate Sertoli cells in aged human testis

W Schulze, C Schulze

    Cell and Tissue Research
    |January 1, 1981
    PubMed
    Summary
    This summary is machine-generated.

    Multinucleate Sertoli cells are common in aged males. Their formation may involve nuclear division without cell division, a process typically seen in immature cells.

    Area of Science:

    • Reproductive Biology
    • Cell Biology
    • Gerontology

    Background:

    • Sertoli cells are crucial for spermatogenesis and male fertility.
    • Aging can impact testicular morphology and function.
    • Previous research has not extensively documented Sertoli cell morphology in aged males.

    Purpose of the Study:

    • To investigate the morphological characteristics of human Sertoli cells in aged males.
    • To explore potential mechanisms behind observed Sertoli cell alterations in aging.

    Main Methods:

    • Light and electron microscopy were used to examine testicular tissue.
    • Tissue samples were obtained from 35 prostate cancer patients (aged 62-84) with no prior cancer therapy.

    Main Results:

    Related Experiment Videos

    • Significant individual variations in germinal epithelium appearance were observed.
    • Multinucleate Sertoli cells were a common finding across all examined cases.
    • In tubules with spermatogenesis, these cells resembled normal variants; in those without germ cells, they showed immature features.

    Conclusions:

    • The nuclei of Sertoli cells in aged males may regain the capacity for division.
    • Mitosis without cytokinesis is hypothesized as a mechanism for multinucleate Sertoli cell formation.
    • These findings suggest aging may induce dedifferentiation-like changes in Sertoli cells.
