Investigations on the uterine lymphatics of juvenile mice, up to the onset of sexual maturity.

By means of orthograde and retrograde application of dyestuffs (using patent blue violet and Japan ink) one can successfully demonstrate the uterine lymphatics in juvenile mice, up to the onset of sexual maturity. However, the three subgroups used here do not show the typical features of the cyclical events of nulliparous and parous mice. However, the morphological changes already present, allow one even now to recognize, that with the increasing sequence of individual sexual cycles, cyclical changes in the uterine lymphatics of the mouse were identified.
