Fig. 7. Expression of Shroom3 in epidermal cells recapitulates the events
underlying neuroepithelial cell shape change. (A) Control epidermis
stained for
-tubulin. (B) Epidermis expressing Shroom3 stained
for
-tubulin. Cells expressing Shroom3 (marked by anti-Myc;
b') constrict and elongate. Parallel arrays of MTs emanate from
the apical cell surface. (C) Control epidermis stained for
-tubulin. (D) Epidermis expressing Shroom3 stained for
-tubulin. Cells expressing Shroom3 in this panel (marked by anti-Myc,
red; d') are only slightly constricted, but are elongated and
contain a broad, diffuse accumulation of
-tubulin. (E) A single
epidermis cell expressing high levels of Shroom3 apically constricts and also
elongates. (e') Anti-
-tubulin staining of the cell shown
in E.
