Regeneración vesical: Células, Andamiajes y Biorreactores

Abstract

Diversas patologías o sus tratamientos quirúrgicos pueden alterar la función de la vejiga urinaria o requerir su extirpación. La vejiga tiene la capacidad de realizar contracciones repetidas y coordinadas para vaciar la orina sin comprometer su capacidad de almacenamiento. Por lo tanto, cuando este órgano está afectado de tal modo que requiere ser extirpado y reemplazado con un órgano completo artificial (o parte de él) producido mediante ingeniería tisular, todas estas propiedades deben ser consideradas con el objetivo de poder reproducirlas. La cistectomía radical y la enterocistoplastia son, hoy en día, los procedimientos estándar para el tratamiento del cáncer músculo-invasivo vesical. Sin embargo, no resuelven la carencia funcional, están asociados a un número no despreciable de complicaciones y generan además un alto coste económico. Por estos motivos, diversos grupos de investigadores en todo el mundo trabajan en estrategias alternativas que permitan conseguir el método ideal de regeneración total o parcial de este órgano. En esta publicación realizamos una profunda revisión del estado del arte de los componentes de este proceso, desde las células hasta la ingeniería tisular y los biorreactores como factores fundamentales en la terapia avanzada de regeneración vesical. La baja producción científica de impacto observada en este campo puede atribuirse a una pérdida de motivación, que se debe a la gran dificultad de conseguir un órgano con una correcta funcionalidad.

Various pathologies or their surgical treatments can alter the function of the urinary bladder or require its removal. The bladder has the ability to perform repeated and coordinated contractions to empty urine without compromising its storage capacity. Therefore, when this organ is affected in such a way that it needs to be excised and replaced with an artificial complete organ (or part of it) produced by tissue engineering, all these properties must be considered in order to be able to reproduce them. Radical cystectomy and enterocystoplasty are, nowadays, the standard procedures for the treatment of muscle-invasive bladder cancer. However, they do not solve the functional problem; they are associated with a non-negligible amount of complications and generate a high economic cost. For these reasons, various groups of researchers around the world are working on alternative strategies to achieve the ideal method of total or partial regeneration of this organ. In this publication, we carry out a thorough review of the state of the art of the components of this process, from cells to tissue engineering and bioreactors as fundamental factors in advanced therapy of bladder regeneration. The low impact that that scientific production observed in this field can be attributed to the loss of motivation, due to the great difficulty of obtaining an organ with correct functionality.
