Friday Whatsit for January 7, 2011
Time for our weekly guessing game, where I put up a picture taken with a microscope and you guess what it is!
This week’s Whatsit is part of a larger picture of tissue stained with H&E (hematoxylin and eosin) a very common stain in medicine.
Your clues: Hematoxylin stains the nucleus of a cell blue. Notice the cells in the middle of the ring-shaped structure. They have no nuclei. Yet they are cells. In fact, they are the only mammalian cells that lose their nuclei at maturity.
What are these cells? You’ve probably seen a lot of this type of cell, just not this up close and personal. Bonus points for the “scientific” name, which has its roots in Greek, not Latin. Extra bonus points for the name of the molecule that makes it possible for these cells to function. Guesses in the comments section, answer on Monday!
