Morphological changes in maternal lymphocytes in pregnancy.

V Knobloch, V Jouja, M Svobodová

    British Journal of Obstetrics and Gynaecology
    |February 1, 1975
    PubMed
    Summary

    During pregnancy, lymphocyte micronucleoli increase significantly, returning to normal postpartum. This study tracked these nuclear changes in healthy women across gestation and after delivery.

    Area of Science:

    • Hematology
    • Cell Biology
    • Reproductive Medicine

    Background:

    • Lymphocyte nucleoli morphology can indicate cellular activity.
    • Pregnancy induces significant physiological changes affecting maternal cells.

    Purpose of the Study:

    • To investigate changes in lymphocyte nucleoli during pregnancy and the postpartum period.
    • To correlate nucleoli morphology with pregnancy status.

    Main Methods:

    • Toluidine blue staining was used to analyze lymphocyte nucleoli.
    • 150 healthy women were categorized into non-pregnant, three trimesters of pregnancy, and postpartum groups.

    Main Results:

    • A statistically significant increase in lymphocytes with micronucleoli was observed during pregnancy.
    • The incidence of ring-shaped nucleoli decreased during pregnancy.
    • Lymphocyte counts and "active" lymphocyte numbers remained unchanged.

    Conclusions:

    • Pregnancy is associated with distinct alterations in lymphocyte nucleoli, specifically an increase in micronucleoli.
    • These nucleolar changes normalize after childbirth.
    • Lymphocyte micronucleoli serve as a potential biomarker for pregnancy-related cellular changes.
