Fig. 3. Amn is not required for cell proliferation or differentiation in fetal
kidney and intestine. Cryosections from E16.5
Amn-/-
+/+ chimeras. (A,C) Two kidney sections and
(B,D) two intestine sections stained with X-gal to identify wild-type (blue
cells indicated by blue arrows) and Amn-/- cells (pink
cells indicated by red arrows). (A) Amn-/- cells colonize
the kidney and contribute to glomeruli (G) and tubules. (B)
Amn-/- cells colonize the intestinal villi (V). (C)
Section of a chimeric kidney containing
100% Amn-/-
cells with normal gross morphology, including properly formed glomeruli (G)
and tubules. (D) A section of chimeric intestine containing
100%
Amn-/- cells with normal morphology and well-formed villi
(V). (E) Chimeric kidney section stained with LTL. (Inset) Kidney cryosection
from an E16.5 Amn+/-
+/+ chimera stained with LTL.
(F) X-gal staining of section adjacent to (E) identifies
Amn-/- cells in properly differentiated proximal tubules
(PT). (Inset) X-gal staining of kidney cryosection from an E16.5
Amn+/-
+/+ chimera.
