[The morphogenesis of vaginal diaphragms. New data]
Summary
This study suggests vaginal septa form from an incompletely resorbed sinus-derived plaque, not a failure of urogenital sinus and Mullerian duct canalization. This finding offers a new perspective on vaginal development anomalies.
Area of Science:
- Embryology
- Reproductive Anatomy
Context:
- Investigates the developmental origins of the vagina.
- Examines theories on transverse vaginal septum formation.
Purpose:
- To propose an alternative theory for vaginal septum formation.
- To explain inconsistencies in existing developmental theories.
Summary:
- Studied seventeen stillborn fetuses with vaginal septa.
- Critiques the urogenital sinus and Mullerian duct canalization theory.
- Proposes the vagina develops from a sinus-derived plaque, with septa resulting from incomplete plaque resorption.
Impact:
- Offers a novel hypothesis for vaginal septum etiology.
- Contributes to understanding congenital reproductive tract anomalies.
- May inform future research on female genital tract development.

Morphogenesis
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.
Mechanism of Lamellipodia Formation
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...
