Fig. 6. Lim1 in the pronephros and cns. (A,A X. laevis neurula. (A) The image is focused in the pronephros. (A Lim1-positive cells of the cns from the embryo in (A). (B,B E. randi neurula. (B) Image focused in the pronephros. (B Lim1-positive cells of the cns from the embryo in (B). (C,C C. machalilla neurula. (C) Image fo- cused in the pronephros. (C Lim1- positive cells of the cns from the embryo in (C). (D,E) G. riobambae neurulae. (D) Lim1 staining of the pronephros and notochord. Cells of the cns were not detected at this stage in G. riobambae em-
bryos. (E) Pronephros and cns Lim1-positive cells from a more advanced embryo. Arrows in ABCand E indicate the Lim1-positive cells of the cns. Abbreviations: n, notochord; p, pronephros, pd, pronephric duct. Scale bars: 400 μm (D); 200 μm (E); 100 μm (A,B,C,C and 50 μm (AB. |
