Does anyone know if fragments are the same thing as schistocytes ?
schistocytes are fragmented red blood cells. not all fragmented cells are schistocytes. cell fragmentation takes place in a few types of cells for a couple of different reasons but the fragments are not always called schistocytes..only when the fragmentation occurs in red blood cells.
Gosh, I thought I was going to be reading about rocks and minerals :jawdrop:
Thanks. I understand what can cause schisocytes. What causes other types of blood cells to fragment?
There's reproductive fragmentation, where asexual cells fragment and then each fragment develops into a fully developed cell which is essentially a copy or clone of the original cell.
There's also programmed cell death, where genes in the cells program proteins to basically break apart dna, the nucleus shrinks and dies and the parts of the cell break apart, or fragment, into apoptotic bodies which are engulfed, or "eaten", by neighboring cells. This process is typically normal and is what happens in adult cells like the skin and gut where there's a lot of epithelial tissue (cells tightly packed together in layers) as part of their normal turn over. The programmed cell death, or apoptosis, also occurs in things like malignant tumors. There's also necrosis, which doesn't typically leave viable fragments but the nucleus and cell organelles swell and rupture their membranes and the fragments and cell disintegrate and die.
Then there's the fragments that occur from irregularities, like in blood that causes schistocytes. It can happen in sperm cells in small concentrations but is exacerbated by things like smoking and drug use. In cells like sperm cells, the fragments are not referred to as schistocytes (despite the fact the word schistocyte is from the greek for divided cell).
White blood cells do not fragment usually, that I am aware of. There was a study of white blood cells fragmenting during transfusion in platelet rich plasma, but beyond that I don't think it happens.
Platelets in blood are already cell fragments. They are bone marrow fragments from large bone marrow cells and they release clotting chemicals at injury sites in the body. They have no nucleus, so are not cells but only fragments when they become part of the blood.
Other than that, there are no more types of blood cells, just plasma. Blood is mostly plasma and red cells, with a small percentage of white and platelets.
Thank you for your response. Are you in the medical field?
Not even a little bit. Building maintenance :thumbup: I read...a lot, and typically non-fiction. Curiousity is like an itch I can't scratch...but not from lack of trying.
We're here to talk 'bout guns and Obamma. Keep that colludge stuff to yourselfs.
Dang Billy good on you, nothing like a building maintanance guy explaining medical terminology. Must be very curious!
Cool! I read a lot too but not a lot of medical stuff. That is my wife's thing. Surprisingly she didn't know if fragments were the same thing schistocytes or not.
The average life expectancy of a red blood cell is 120 days. Because of that, we are constantly rebuilding our red blood cells - they break down, the body absorbs the "good" bits, flushes the rest and we keep on keeping on. The body doesn't waste much.
