Fig. 10. Solubility of FN fibrils in urea. (a,b) Fibril formation was induced in stage 9 blastocoel roofs and allowed to proceed for 10 minutes. Deposited fibrils were incubated for 30 minutes in MBS (a; control) or 3 M urea in MBS (b). After extraction with urea, only faint traces of FN fibrils are left (arrowheads). (c) About 2 hours after the onset of FN fibril formation, at stage 10 , fibrils were transfered to plastic and incubated in 3 M urea in MBS for 30 minutes. Arrowheads, traces of extracted FN fibrils. Arrow, FN fibril resistant to extraction by urea. Image published in: Winklbauer R and Stoltz C (1995) Copyright © 1995.
