Abstract

Cover Photograph:Upper left: Newt (P. waltl) juveniles and Xenopus froglets were subjected to agarose‐embedded heat‐shock (AeHS) method. GFP expression was induced specifically in the regenerating limbs (see Matsubara et al. 86–93).Upper right: Schematic diagram of the intermittent hypoxia exposure model. Pimonidazole‐positive cells were detected in the pulmonary tissues of Xenopus laevis during repeated dives, indicating tissue hypoxia (see Fujiyama, 94–99).Lower left: The intercalary element of Zhangixalus schlegelii (arrowheads). Such skeletal elements are seen between the terminal and subterminal phalanges of all the digits of arboreal frogs (see Nakanishi, 100–108).Lower right: Tetraspanin9 expressions in Xenopus laevis (above) and X. tropicalis embryo (below) hybridized in the same tube. (see Kuriyama and Tanaka, 109–119).Bottom right corner: A 48 hpf early four‐armed pluteus taken through a confocal microscope. Catecholamine‐positive cells are colored in yellow (see Kalachev and Tankovich, 120–131). image
