Abstract
The luminal epithelium of the mouse uterus was removed simply and rapidly by opening the uterine horns longitudinally and vortexing them in buffer with glass balls. This procedure, which requires no specialized apparatus, was developed for use with uteri in different hormonal states and 2 uterine horns/tube, 5 glass balls and vortexing for 2 min are suggested for routine use. Under these conditions, 79-100% of the cells were removed, yielding epithelial fractions of 65-90% purity. The suspension of cell constituents recovered contained intact nuclei which could be further purified. Extensive histological examination demonstrated that the other uterine tissues were minimally damaged.
