Abstract
El presente trabajo de investigación tuvo como objetivo determinar concentración de la hormona Anti Mülleriana en el plasma sanguíneo de alpacas hembras. La metodología utilizada fue mediante técnica Elisa sándwich, usando un kit comercial AnshLabs rata/ratón AMH ELISA específico para ratones. Para la validación de este kit en alpacas, se utilizó diluciones seriadas de líquido folicular de alpacas hembras, plasma de alpacas macho castrados y plasma de alpacas hembras adultas, observándose linealidad y paralelismo con respecto a la curva estándar. Al evaluar la concentración de la hormona Anti Mülleriana durante la onda folicular, se observa datos muy variados entre los individuos. Sin embargo no presentan ningún patrón asociado con la onda folicular. La concentración de hormona AMH en el plasma de alpacas, está fuertemente correlacionado (r=0.6) con el conteo de folículos antrales. Presentando valores máximos de 3.129 ng/ml y mínimos de 0.37 ng/ml. La tinción inmunohistoquímica muestra que la expresión de la hormona Anti-Mülleriana se restringe a las células de la granulosa de folículos pre-antrales y pequeños antrales, ausentándose dicha expresión en los folículos primordiales y atrésicos. En conclusión, la concentración de hormona Anti-Mülleriana se determina mediante un kit comercial específico de rata y puede utilizarse como un marcador de la reserva ovárica en alpacas
The aimed of this study was to determine the concentration of the Anti-Müllerian hormone (AMH) in the blood plasma of female alpacas. The methodology used the Elisa sandwich technique, with a commercial kit AMH- ELISA AnshLabs rat/mouse specific for mice. For the validation of this kit in alpacas, serial dilutions of follicular fluid of female alpacas, plasma of male castrated alpacas and plasma of adult female alpacas were used, observing linearity and parallelism with respect to the standard curve. When evaluating the concentration of the anti-Müllerian hormone during the follicular wave, very varied data were observed between individuals. However, these do not present any pattern associated with follicular wave. The concentration of AMH hormone in the plasma of alpacas is strongly correlated (r=0.6) with antral follicle count. Maximum values were 3,129 ng/ml and minimum values were 0.37 ng/ml. AMH expression was assessed using immunohistochemistry in ovarian from alpacas. Immunohistochemistry staining showed that AMH expression was present in the granulosa cells of pre-antral and small antral follicles, and this expression was absent in the primordial and follicles undergo atresia. In conclusion, the concentration of Anti-Müllerian hormone was determined by a commercial rat-specific kit and can be used as a marker of the ovarian reserve in alpacas
