Caption

Electron microscopy of spermatids from Krt19^tm1Alki/Krt19^tm1Alki mice displaying ectopic manchettes. A: The arrows indicate the association of the dense perinuclear ring of the manchette with the plasma membrane. The distribution of manchette microtubules around the spermatid nucleus is indicated. B: Spermatid nucleus with a deep infold harboring a dense mass (arrow) corresponding to the perinuclear ring of the manchette and a microtubule bundle. The position of the bulk manchette microtubules is indicated.
