Fig. 6 Inhibition of Notch signalling results in loss of segment formation in Xenopus embryos. a–f DAPT treatment did not affect the expression
pattern of Gsc (a n = 42, 93 %; b n = 38, 87 %) and Brachyury (c n = 20, 95 %; d n = 14, 94 %), whereas it disrupted the paired-stripe expression
pattern of Delta-2 (e n = 33, 100 %; f n = 47, 51 %). a–b Anterior views with dorsal side up. c–f Dorsal views with the anterior side up. g–h DAPT
treatment resulted in loss of segmental expression of Mrf1 in amphioxus (g n = 12, 100 %; h n = 11, 100 %. Dorsal views with anterior to the left),
MyoD in Xenopus (i n = 23, 100 %; j n = 15, 93 %), and Tbx1 (k n = 23, 100 %; l n = 13, 54 %). i, j The lower left panel displays the magnification of
the somite expression of MyoD |
