| Without proper nutrition, feathers become dry and lack-luster, may break easily and lack normal ultrastructure. |
| So may the histologist looking at the ultrastructure of dying tissue through an electron microscope. |
| The ultrastructure of normal cilia consists of nine outer microtubule pairs and two single central microtubules. |
| These are the finest ultrastructure details thus far found in microbes preserved by hydrothermal mineralization, and can be used as an aid to identify microfossils. |
| Histology, immunohistochemistry, and ultrastructure were highly suggestive of transdifferentiation from cardiac muscle to adipose tissue. |
| Changes in the structure and ultrastructure of protoplasts during regeneration of the cell wall, mitotic cell division and amitotic nuclear fragmentation. |
