Discussion of all aspects of cellular structure, physiology and communication.
Hey, I looked all over the place and I came up empty - If I see something I will post it here
No amount of experimentation can ever prove me right; a single experiment can prove me wrong.
I tend to agree with Thenewguy. The stem cell is not a specialised cell, it's main purpose is to divide and create more cells. I am not sure of this as I also couldn't find the size in any of my books but this is my opinion
The stem cells that form blood and immune cells are known as hematopoietic stem cells (HSC).
A major thrust of basic HSC research since the 1960s has been identifying and characterizing these stem cells.
Because HSCs look and behave in culture like ordinary white blood cells, this has been a difficult challenge and this makes them difficult to identify by morphology (size and shape).
Even today, scientists must rely on cell surface proteins, which serve, only roughly, as markers of white blood cells.
Stromal cells can be obtained from a little sample of patient’s bone marrow.
Stem cells are basically the same size as blood cells, and in many instances the same shape.
stem cells are 20 nm in size. but they are different in function
aah..it is totally absurd to give a specific size as 20um to all stem cells! I wonder what's the source of this info?
The stem cells that I work with (Adult bone marrow stem cells) can vary in size from 5 to 50 microns.
