title: A new method for the preparation of mammalian spermatogonial chromosomes.
abstract: After the seminiferous tubules were minced and washed with phosphate-buffered saline to remove sperms, spermatids and spermatocytes (Hoo and Bowles, 1971), they were repeatedly treated with 0.1% trypsin solution to liberate spermatogonia. It was concluded that the spermatogonial chromosomes can be analysed much more easily and accurately by this procedure than by previous ones.
