Vulva morphogenesis involves attraction of plexin 1-expressing primordial vulva cells to semaphorin 1a sequentially expressed at the vulva midline

Vulva morphogenesis involves attraction of plexin 1-expressing primordial vulva cells to semaphorin 1a sequentially expressed at the vulva midline.

Vulva development in C. elegans involves cell fate specification followed by a morphogenesis phase in which homologous mirror image pairs within a linear array of primordial vulva cells form a crescent shape as they move sequentially towards a midline position within the array. The homologous pairs from opposite half vulvae in fixed sequence fuse with one another at their leading tips to form r...

Morphogenesis of the caenorhabditis elegans vulva.

Understanding how cells move, change shape, and alter cellular behaviors to form organs, a process termed morphogenesis, is one of the great challenges of developmental biology. Formation of the Caenorhabditis elegans vulva is a powerful, simple, and experimentally accessible model for elucidating how morphogenetic processes produce an organ. In the first step of vulval development, three epith...

Fibroadenoma Of The Vulva: A Case Report

  Fibroadenoma of the vulva is an uncommon lesion. It has been suggested that they originate from vulvar mammary like other glands. A few examples of benign and malignant vulvar tumors arising from such glands have been reported. A 32-year-old woman was referred with a subcutaneous mass at the vulva. The patient treated by simple excisional surgery with adequate peripheral margin. Histologic...

Leiomyoma of the Vulva.

[Endometriosis of the vulva].

The greater labium is an uncommon site for endometriosis. Cases have been described by Palmer (I925), Henry (i927) and others. The lesion usually consists of a small red nodule painful during menstruation, slowly enlarging and consisting histologically of small blood filled cysts lined by columnar epithelium, in places forming typical endometrial glandular structures; the stroma consisting of f...
