Re: Non-Specialized cell

[Russ Johnson <rujohnso@nmsu.edu>]

Since you're a tech trainer like me, I'll take a shot at this. The brain is an

organ (not a cell as stated), and all organs by definition are specialized. I'm

pretty sure of that. The brain could be considered unspecialized only perhaps

during the first trimester, in utero. That brings in the context of maturity as

a function of degree of specialization. Essentially, all immature cells are

unspecialized. But, later on when the DNA information activates, the cell

begins to perform its function and becomes specialized. I think that's what

Gollnick is getting at on pages 62 and 62 in Basic Radiaton Protection

Technology, 1983.
