La infertilidad es un problema que afecta a una fracción importante de la población. Existen numerosos métodos para tratarla, como las técnicas de reproducción asistida (TRA); sin embargo, todas las TRA requieren el uso de gametos por lo que parejas sin gametos funcionales solo pueden recurrir a la donación de gametos. En los últimos años el campo de las células madre, las cuales presentan la capacidad de autorregenerarse y diferenciarse en diversos tipos celulares especializadas, ha avanzado notablemente y numerosos esfuerzos se han llevado a cabo para su uso en medicina reproductiva. Aunque se han realizado muchos estudios en modelos animales donde se han generado gametos in vitro a partir de distintos tipos de células madre, aún no se han generado gametos humanos seguros por lo que se requiere más investigación. En este trabajo, resumimos los avances actuales del uso de células madre en el campo de la reproducción, centrándonos en su posible uso en la derivación de gametos.
Infertility affects a significant part of the population. There are many methods to treat these conditions, such as assisted reproductive techniques (ART); however, all ART require gametes, so couples without functional gametes can only resort to gamete donation. In recent years, the field of stem cells, which have the ability to self-regenerate and differentiate into various specialized cell types, has made remarkable advances and numerous efforts have been made to use them in reproductive medicine. Although many studies have been conducted in animal models where gametes have been generated in vitro from different stem cells, safe human gametes have not yet been generated and further research is required. Here, we summarize the current advances in the use of stem cells in reproduction, focussing on their potential use in gamete production.
