Carbon monoxide has a simple but
distinctive outermost orbital structure with two side - by - side lobes sticking out from the end of the tip, one with a positive phase and the other a negative phase.
Confocal images of sections of the seminiferous tubules illustrated the existence of various iPS cell - derived EGFP - positive cells, including flattened fibroblast cell - like myoid at the
outermost layer of the tubules, spermatogonial stem cells with spherical nuclei closest to the basement membrane and spermatocytes with
distinctive chromatin closer to the lumen than spermatogonial stem cells (Figure 6D).
