Abstract
Despite the numerous histological studies on regenerating tails, few ultrastructural studies have been conducted on the progressive stages of the process. These studies would allow a better identification of the modification of injured tissues and of the different cell types activated during the process of wounding. No ultrastructural studies are available for the wounding and the limited tissue regeneration of the limb.
Only the regenerating spinal cord has received a detailed transmission electron microscopy (TEM) analysis (Simpson 1968; Egar et al. 1970; Turner and Singer 1973; Alibardi 1990–1991). Other ultrastructural studies have been conducted on the differentiation of the main tissues in the tail (see later). These studies have permitted us to determine precisely the types of cells involved in the formation of the regenerative blastema in lizards and the proliferative potential of cells of the connective, ependymal, muscular, and blood tissues.
The following sections provide a summary of published and unpublished observations on the fine structure of the wounded and regenerating tissues of different species of lizards. More details can be found in specific publications cited in the following sections.
