It consists of the segmentation of tubules in serial paraffin sections of the testis by marking the basement membrane with periodic acid-Schiff or a fluorescent anti-laminin antibody followed by the 3D reconstruction of tubules with high-performance software. Using this method, we analyzed testes from mice at different ages and accurately elucidated the 3D structure of seminiferous tubules, including the number and length of tubules as well as the numbers of connections with the rete testis, branching points, and blind ends. We also analyzed the distribution and direction of spermatogenic waves along the length of adult seminiferous tubules as well as the site of the first onset of spermatogenesis in postnatal seminiferous tubules., 研究課題/領域番号:16K18976, 研究期間(年度):2016-04-01 - 2019-03-31, 出典:研究課題「精細管の三次元構造と精子形成能の空間的「偏り」の解明」課題番号16K18976 (KAKEN:科学研究費助成事業データベース(国立情報学研究所)) (https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16K18976/16K18976seika/)を加工して作成}, title = {精細管の三次元構造と精子形成能の空間的「偏り」の解明}, year = {2019} }
