La présence de grains d’argent (points noirs) aux différentes hauteurs de l’épiderme révèle une extraordinaire particularité du tégument de poissons, à savoir qu'il comporte des cellules vivantes sur toute son épaisseur et peut être le siège de divisions cellulaires à tous niveaux, même superficiels. Cette spécificité, particulièrement avantageuse lors de maladie ou de blessure, montre une différence fondamentale avec l’épiderme de mammifère où seules les cellules de la couche basale (stratum germinativum) se divisent par mitoses ! - Pour plus de détails ou précisions, voir « Atlas of Fish Histology » CRC Press, ou « Histologie illustrée du poisson » (QUAE) ou s'adresser à Franck Genten (fgenten@gmail.com) ---------------------------------------------------------------------------------- An autoradiograph of section of zebrafish side skin from a specimen intraperitoneally injected with tritiated thymidine (thymidine linked to the radioisotope tritium) one hour previously.

Mitosis in root tip of Broad Bean (Vicia faba) 2/2
The image shows a longitudinal section of a root tip of Broad Bean (Vicia faba) with cells from the region of cell division, just behind the root cap. (See also Mitosis in root tip of Broad Bean (Vicia faba)). This image includes a number of cells in various stages of mitosis, as well as cells in interphase. The nucleoli of the cells in interphase are clearly visible. Nucleoli are the sites of synthesis of ribosomal RNA. When mitosis takes place, the nucleoli disappear and the nuclear membrane breaks down. During the prophase of mitosis, the DNA coils and condenses so that the chromosomes become visible. At metaphase the chromosomes, each consisting of two chromatids, align themselves along the spindle equator. During metaphase the chromatids separate to the poles of the cell. During the final stage of mitosis (telophase) the newly formed chromosomes reach the poles and unwind again, forming an amorphous mass called chromatin, which, with the formation of a new nuclear membrane and nucleoli, becomes a nucleus of a daughter cell. In plant cells, cell division is completed by the synthesis of a cell wall between the daughter nuclei. A number of daughter cell pairs are visible in this image. The diameter of the smaller cells (in interphase) is about 20 µm. Image by Leighton Dann

Mitosis in root tip of Broad Bean (Vicia faba) 1/2
The image shows a longitudinal section of a root tip of Broad Bean (Vicia faba) with cells from the region of cell division, just behind the root cap. (See also Vicia root tip Is2). This meristematic tissue is the site of intense mitotic activity as the root tip grows down through the soil. Mitosis is the process of nuclear division that produces two genetically identical daughter cells, each with the diploid chromosome number. Between mitotic divisions, a cell is in a stage called interphase. A number of cells in interphase are visible to the right of the image. They are small, with their nuclei occupying a large proportion of each cell’s volume. Inside many nuclei, darker spots are visible, which are the nucleoli. During interphase, the DNA is replicated ready for its partitioning into the two daughter cells. To the top left of the image a cell in late prophase / early metaphase can be seen. Here the chromosomes are visible and the nuclear membrane has broken down. The chromosomes are beginning to arrange themselves along the equator of the spindle (not visible at this magnification). In the middle of the image is a cell in late anaphase. The copies of each chromosome (chromatids) have separated towards the poles of the cell. The diameter of the smaller cells (in interphase) is about 20 µm. Image by Leighton Dann

The term atypical carcinoid may be somewhat misleading since it may give the impression of a low grade of malignancy when if fact these are fully malignant neoplasms in which distant metastases are present in about 20% of patients at presentation and the disease free survival after 10 years is about 50%. An alternate name - neuroendocrine carcinoma grade 2 - has been suggested. I believe that this is preferable to atypical carcinoid but others are unwilling to accept this terminology.

Woo cell extraction from onion root tips! This is not to say that onion cells are naturally pink; these were dyed with aceto-orcein stain for greater visibility. I was a bit disappointed, honestly, because I was under the impression that we were going to be able to see the cells in more definition than we did. But it was still pretty neat even if we couldn't observe the many stages of mitosis (darn, like I don't know what those look like...). =P And apart from the obvious (equilateral??) triangle, the curves almost make it look like a fingerprint. Which I suppose it is, in a way.

Lesión intraepitelial escamosa de alto grado (HSIL)
Proliferación de células escamosas que afecta al espesor completo, con mitosis a varios niveles. Hipercromatismo. Algún núcleo muy grande.
Lesión intraepitelial escamosa de alto grado (HSIL, CIN2-3)
Proliferación de células escamosas del cuello uterino, con pérdida de polaridad, de entre 2/3 y el espesor completo. En algunas de las imágenes se ven figuras mitóticas de forma anormal.
Animal Cell Mitossi
Mitosis in an animal cell. Cells from the Chinese Hamster Ovary are shown undergoing mitosis. Beginning with a cell spread on the substrate, follow prophase, anaphase, metaphase, telophase, cytokinesis and reattachment of the two daughter cells to the substrate.

Osteosarcoma (H&E)
An H&E image from a case of conventional osteosarcoma involving proximal tibia. Other areas had cartilaginous and giant celled morphology. In addition to mitosis (upper left) and cellular atypia (everywhere), which are usual; one should see the atypical osteoid (upper right) to make the diagnosis. The patient was a 14-year-old boy.
