The aim of this study was to establish a three dimensional (3D) culture system of endometrial cells and to examine the plasminogen activators (PAs) activity in porcine uterine. The 3D culture system in porcine endometrial cells was composed to mixture 3D gel, stromal cells and epithelial cells. The 3D culture system was used to identify normal structure search as uterine tissue and PAs expression in this study. In results, porcine endometrium epithelial cells forming a top monolayer and endometrium stromal cells developed as fibroblast-like within 3D matrix scaffold. Expression of urokinase-type PA (uPA) and tissue-type PA (tPA) were observed during the 3D culture using immunofluorescence. PA activity in 3D-cultured endometrial cells was no significant difference between the tissue type, but 2D culture system were significantly lower than in 3D-cultured endometrial cells (P<0.05). Therefore, basic system and functional aspect of 3D culture could be established with similar system of endometrium tissue. We suggest that this study was assumed applicable as baseline data to investigate mechanism between porcine uterus cells in vitro.
