Gebhardt et al. performed a microarray analysis of endometrial tissue samples from 5 normal-cycling warmblood mares to study the dynamics of equine endometrial gene expression. Samples were obtained by transcervical biopsy and taken at 5 different time points (days 0, 3, 8, 12, and 16) during the estrous cycle.
