RESUMEN

La ingeniería tisular basada en las células troncales de pulpa dental se considera como un enfoque prometedor para la odontología regenerativa, con el objetivo final de reemplazar morfológica y funcionalmente los tejidos periodontales y/o los dientes perdidos a través de la síntesis in vitro de sustitutos análogos tisulares o, incluso, de un diente humano denominado biodiente. Las células troncales de la pulpa dental representan una colonia de células adultas que tienen la capacidad de autorrenovación y diferenciación en diferentes linajes. El origen exacto de las células troncales de la pulpa dental no ha sido completamente determinado y estas células troncales parecen ser la fuente de los odontoblastos que contribuyen a la formación del complejo dentinopulpar. Recientemente, los logros obtenidos a partir de la investigación de las células troncales nos han permitido contemplar las posibles aplicaciones terapéuticas de las células troncales de la pulpa dental. Algunos estudios han demostrado que las células troncales de la pulpa dental son capaces de producir tejidos dentales in vivo, incluyendo la dentina, la pulpa dental y las estructuras de la corona. Mientras que otras investigaciones han demostrado que estas células troncales se diferencian in vitro e in vivo, por ejemplo, en osteoblastos, neuroblastos, condrocitos, fibroblastos y endotelio. En teoría, un biodiente sintetizado a partir de las células troncales de la pulpa dental debe ser la mejor opción para recuperar la totalidad de la estructura y función de un diente humano. El objetivo de este artículo de revisión es hacer una breve descripción de la localización, origen, aislamiento y marcadores candidatos de células troncales de pulpa dental, para así plantear las perspectivas de aplicación en la clínica odontológica.
