IN VITRO OBTAINMENT OF STEM-LIKE CELLS FROM GUBERNACULUM TESTIS BIOPSIES OF CRYPTORCHID PEDIATRIC PATIENTS.

Testicular descent is a crucial event in male sexual development, and alterations in this process during gestation can lead to reduced fertility in adulthood. Cryptorchidism, i.e., failure of one or both testicles to descend into the scrotum, is one of the most common birth defects and represents a principal cause of infertility in adulthood. Therefore, identifying effective approaches for preserving fertility in childhood is of primary importance. In this context, the key role played by the gubernaculum testis during the placement of the testes in the scrotal bursa emerges. Given its close affinity to testicular tissue and its richness in mesenchymal cells, our prime aim is to characterize this para-testicular tissue to explore its potential ability to differentiate into testicular cells for fertility preservation. The first step of our task is represented by the present study that aimed to obtain in vitro stem-like cells starting from gubernaculum testis biopsies of four pediatric patients affected by cryptorchidism, aiming to differentiate them into testicular functioning cells. Our results show that the obtainment of aggregates with stem features is not dependent on the age of the patients and, therefore, not even on the damage suffered by the testis during its stay in the abdomen. This study opens the possibility of extending this approach to older patients, offering a new potential approach to support their fertility potential.
