The genital ridge (or gonadal ridge) is the precursor to the gonads. The genital ridge initially consists mainly of mesenchyme and cells of underlying mesonephric origin. Once oogonia enter this area they attempt to associate with these somatic cells. Development proceeds and the oogonia become fully surrounded by a layer of cells (pre-granulosa cells). The genital ridge appears at approximately five weeks, and gives rise to the sex cords.

  • Die Genitalleiste ist die Anlage der Keimdrüsen (Gonaden) bei einem Embryo. Sie ist eine beidseitige, längsverlaufende Verdickung des Epithels des Zöloms und des darunter liegenden Mesenchyms, die sich in der 4. Entwicklungswoche – am 26. Tag der Keimesentwicklung – bildet, und aus der sich in der Folge die Gonaden entwickeln. Die Genitalleisten liegen damit an der Leibeshinterwand zwischen hinterem Mesenterium und den ebenfalls beidseitig angelegten Urnierenleisten. Bei den meisten Wirbeltieren bildet nur der Mittelabschnitt dieser Anlage die Keimdrüse, der vordere und hintere Teil wird zu den Keimdrüsenbändern. In Frühstadium der Entwicklung ist es noch nicht möglich, zwischen männlicher und weiblicher Genitalentwicklung zu unterscheiden: Das Geschlecht ist bei den meisten Tieren genetisch bestimmt. Keimzellen sind in der Genitalleiste noch nicht vorhanden. Diese wandern als Urkeimzellen ab der 5. Entwicklungswoche von der Wand des Dottersackes über das Mesenterium des Enddarms Richtung Genitalleiste und erreichen diese in der 6. Entwicklungswoche. (de)

Pode se diferenciar em ovário ou testículo, dependendo essencialmente do genótipo sexual do indivíduo (Tanaka 2014). Em humanos, as cristas gonadais se formam do espessamento da epiderme na superfície ventral do mesonéfro durante a quarta semana pós-fertilização. Esse processo se dá por, dentre outros, muitos fatores de transcrição da família homeobox, como: LHX1 (Shawlot 1995) e LHX9 (Birk 2000). Essas cristas são compostas de linhagens de células somáticas e células germinativas, essas duas se formando em locais e momentos embrionários diferentes durante a ontogenia do embrião (Tanaka 2014). Durante os primeiros dias embrionários, essas cristas indiferenciadas ja desenvolvem dutos sexuais, até que durante a diferenciação sexual um dos dutos é degenerado, conforme o sexo cromossômico do indivíduo (Rey 2000-).
