Gorgeous expression of desmosomes joining keratinocytes

When the Human Cell Atlas began, no one knew how many types of cell there were. The answer turns out to be: “a lot more than people once thought” econ.st/3yuBqxY

Cross Section of a human female ovary. Can you name the major structures seen? Isn’t it beautiful? #histology #MedEd #MedTwitter #ThreadEd Dr Ihab Suliman

2/🧵 Cross section of a human female ovary. That is what makes a human female, a woman 😀

The blue dense areas are most likely corpora albicantia (plural of corpus albicans), scars formed where corpora lutea (plural of corpus luteum) used to exist

Histology students always expect mast cells to be stained with stains that yield metachromasia, as toluidine blue. With HE, notice the contrast with the neighbouring cells (cytoplasm is more red, brighter) and the finely granular pattern of the cytoplasm. Practice!

Indeed: abundant amyloid may elicit birrefringence even if Congo Red is not used. It is always an interesting experience to try to detect it without the use of that dye, in the HE stained tissue. Fantastic image!

The author meant osteoclasts, which are also multinucleated. Osteoblasts are mononuclear. Also remember that osteoclasts are not macrophages.

NZ and the MRNA Angus Dalgleish was allegedly trying to sell a vaccine to compete with Pfizer/Astra Zeneca that he had shares in. Wouldn't trust him as far as you could throw him.
