Anuran heart development and critical developmental periods : a comparative analysis of three neotropical anuran species

The heart begins to form early during vertebrate development and is the first functional organ of the embryo. This study aimed to describe and compare the heart development in three Neotropical anuran species, Physalaemus albonotatus, Elachistocleis bicolor, and Scinax nasicus. Different Gosner Stag...

This study aimed to describe and compare the heart development in three Neotropical anuran species, Physalaemus albonotatus, Elachistocleis bicolor, and Scinax nasicus. Different Gosner Stages (GS) of embryos (GS 18–20) and premetamorphic (GS 21–25), prometamorphic (GS 26–41), and metamorphic (GS 42–46) tadpoles were analyzed using stereoscopic microscopy and Scanning Electronic Microscopy.

In addition, different patterns of melanophores arrangement were observed. During the embryonic and metamorphic periods, the main morphogenetic events occur: formation of the heart tube, regionalization of the heart compartments, development of spiral valve, onset of heartbeat, looping, and final displacement of the atrium and its complete septation. Both periods are critical for the normal morphogenesis and the correct functioning of the anuran heart. These results are useful to characterize the normal anuran heart morphology and to identify possible abnormalities caused by exposure to environmental contaminants. 2023-08-28T13:14:09Z 2023-08-28T13:14:09Z 2022 Artículo Sandoval, María Teresa, et al., 2022.
