Abstract

During alpaca testis development and spermatogenesis, nerve growth factor (NGF) may play an important role. The main aim of this study was to determine the expression and localization of NGF in the alpaca testis, and to discuss the important role of NGF in alpaca reproductive characteristics. Immunohistochemical staining technique and real-time PCR were used. The expression of NGF in the same cells one-month old (newborn) alpacas 12-month, and 24-month old alpacas showed significant differences (p < 0.05); 12- and 24-month old alpacas showed no significant differences (p > 0.05); NGF at different cell stages showed no significant differences (p > 0.05). It suggests that NGF may be involved in the regulation of spermatogenesis, which provides direct evidence for NGF action in the alpaca testis during postnatal development and spermatogenesis.
