What kind of epithelial cell? Every surface’s epithelium will be different.

If you want a feel for the subject, do a Google search on epithelial ultrastructure (ultrastructure is subcellular anatomy). You’ll notice all of the sources specify particular types of epithelial cells.

We need specific question 😉

Hello Dr. Stein,

I came across your postings at biology-online.org and I think you are clearly an expert I can count on.

Please tell me (as I am a clinical psychologist & psychiatric epidemiologist/ not biologist) but have access to serum samples, where can I find a readily accessible (web?) comprehensive list of assays that can be conducted using serum? I am trying to determine whether such biochemicals/potential markers such as immune agents (e.g., cytokines, interleukines), stress related hormones (e.g., ACTH, cortisol, CRF, etc), and possibly infectious disease agents (e.g., plasmodium gondi) can be identified reliably in serum? Oh, and why not DNA… I know there are no white blood cells, but why not the possibility of propogating fragments that certainly are there to be found???

Thanks so much for your time, shared wisdom, and assistance.

Best,
steve

We can classify epithelial cells by it’s Shape ,Stratification, Specializations.

The general function of epithelial cells are including secretion, absorption, protection, transcellular transport, sensation detection, and selective permeability.

But we need perticular query to solve.

Thank You
