LECTINHISTOCHEMISTRY STUDY OF THE UTERUS OF ALPACAS (Vicugna pacos)UNDER SUPEROVULATION TREATMENT
The aim of this study was to determine the glycosylation pattern in the uterine endometrium of alpacas with and without superovulation treatment. Uterine tissues were obtained from five non-treated alpacas with ovarian follicles less than 4 mm and five superovulated alpacas where FSH, GnRH and hCG was used. Samples from theuterus and uterine horns were analyzed by histochemistry (PAS and alcian blue) and lectinhistochemistry techniques. Fourteen lectins were used and PNA, RCA-1, ConA, DBA, WGA, Swga, GS, LCA, SJA and PHA-L showed different glycosilation patterns in the endometrium between both groups, indicating that the hormonal treatment could affect the expression of glycoconjugates that have affinity for these lectins. Lectins PNA, SJA, SBA, ConA, LCA and PSA showed different glycosilation patterns between the two uterine horns, indicating that the glycoconjugates that have affinity for these lectins can be implicated in the uterine environment during the implantation, which in most cases in the alpaca take place on the left horn. In conclusion, the glycosylation pattern in the alpaca can change due to superovulation hormone therapy.
