Los protocolos actuales describen nuevas imágenes de montaje completo para la visualización de estructuras periféricas en el cristalino ocular con métodos para la cuantificación de imágenes. Estos protocolos se pueden utilizar en estudios para comprender mejor la relación entre las estructuras a microescala del cristalino y el desarrollo/función del cristalino.

Nuestro objetivo es determinar los mecanismos moleculares que establecen la intrincada arquitectura de la lente y cómo esta arquitectura establecida regula la función de la lente en la transparencia y el cambio de forma de la lente. Para avanzar en la investigación en nuestro campo, utilizamos nuevos métodos de imagen que nos permiten visualizar las características de la lente con alta resolución espacial, y esto nos permite realizar un análisis cuantitativo de imágenes de las estructuras de la lente y las características celulares. La obtención de imágenes de montaje completo es ventajosa sobre la visualización de secciones de tejido o procedimientos de montaje plano, ya que permite la preservación de la estructura general del tejido en 3D.

Esto nos permite realizar un examen morfométrico en profundidad y una cuantificación de la estructura nativa de la lente. El cristalino es un tejido biológico integrado con funciones especializadas que dependen de la localización y las geometrías dependientes de la profundidad de las células y sus estructuras asociadas. El uso de los protocolos de imagen y los métodos de cuantificación demostrados, permitirá una mayor comprensión de cómo se establecen las estructuras de la lente y la compleja organización de la lente.
