What is osteoblastin?

(I tried googling it, but all that came up was, "osteoblast in." <---I don't want that. I want "osteoblastin." One word.)

I just googled it with quotes (i.e. "osteoblastin") and came up with one maybe research article, a bunch of stuff about the AAMC #9, and a whole lot of gibberish. Which suggests to me that it's either a made up hormone/enzyme for the MCAT, or something that's not necessary to know b/c it's not studied very much.
So perhaps just read as "enzyme/hormone X" instead of "osteoblastin" if you're looking at it on a practice test.

Haha I just saw this on AAMC #9 today, too...

I don't think you needed to know what it was, the passage and the table had what you needed.

Just make sure you know about:

-osteoblasts (increases bone formation)
-osteoclasts (increases bone break down)
-calcitonin (decreases blood calcium)
-and PTH (increases blood calcium)
