  1. Blood vessel formation during tail regeneration in the leopard gecko (Eublepharis macularius): The blastema is not avascular

    A comparison of the cross-sectional anatomy an original leopard gecko tail (left) with that of a fully regenerated tail (right). New blood vessels first form within days of tail loss, demonstrating that the blastema (the accumulation of cells giving rise to the new tail) is not avascular. Restoration of the vascular system closely matches the formation of regenerated tail tissue and involves the dynamic expression of pro- and anti-angiogenic factors.

  2. The ultrastructural characterization of mitochondria-rich cells as a response to variations in salinity in two types of teleostean pseudobranch: milkfish (Chanos chanos) and Mozambique tilapia (Oreochromis mossambicus)

    Sheng-Hui Yang, Jeng-Dau Tsai, Chao-Kai Kang, Wen-Kai Yang, Hsiu-Ni Kung and Tsung-Han Lee

    The mitochondria in the pseudobranch type cells of freshwater-acclimated milkfish and tilapia were larger. More tubules were found to aggregately surround the mitochondria and basolateral membranes in the pseudobranch type cells of fish from the hypo-osmotic environment.

  3. A whole lamella perspective on the origin of the epidermal free margin of Anolis (Reptilia: Dactyloidae) toe pads

    This longitudinal section of part of the adhesive toe pad of an anole (ventral to the bottom, distal to the right) shows the overlapping lamellar plates carrying the setae that are responsible for adhesion. Skin shedding, and therefore replacement of the setae, occurs frequently (once every 30–35 days) and continuity of adhesive function is imperative as the new epidermal generation develops and the outer epidermal generation is ultimately shed. To achieve this the individual lamellae increase in length by about two-thirds as the generative stages of the shedding cycle are passed through, carrying the exposed setae with them and creating space more proximally for the development of the replacement setae. When the outer epidermal generation (and its setae) is shed, the replacement setae are exposed and positioned so as to make up the new continuous carpet of adhesive structures. With the loss of the outer epidermal generation the lamellae return to their original length and, after a resting period, the proliferative cycle begins again.
