TC Update
I ordered an expensive new cells from a company a couple weeks ago, thawed them out in the fresh and clean incubator (with no other occupants) and guess what?
Yep. Not the bleb monsters, but the spindly, leaving bits of themselves behind, non-mitotic problem again.
Turns out we (the lab) had switched FBS (fetal bovine serum) from HyClone to Atlanta Biologicals because we "got a good deal" and "the 3T3 cells looked okay". Gah! (By the way, the 3T3's don't really look okay.) So I threw some Clonetics FBS on my cells (along with some mycoplasma treatment, just in case) and lo and behold: they expand, with reasonably normal looking morphology.
My peoples - you can't just go around changing FBS and expect everything to be hunky-dory.
I think the terrible problems of April-May were a combination of cells being sickly, not liking the discount FBS (expensive tastes, wouldn't you know), and being consequently even more sensitive to whatever maux was griming up the incubators and t.c. hoods.
So now: lots of experiments, and ordering expensive things, and more experiments. And writing a paper. I really need to get this story done and out.
