A monoclonal antibody specific for Xenopus MyoD (XMyoD) has been characterized and used to describe the pattern of expression of this myogenic factor in early frog development. The antibody recognizes an epitope close to the N terminus of the products of both XMyoD genes, but does not bind XMyf5 or XMRF4, the other two myogenic factors that have been described in Xenopus. It reacts in embryo extracts only with XMyoD, which is extensively phosphorylated in the embryo. The distribution of XMyoD protein, seen in sections and whole-mounts, and by immunoblotting, closely follows that of XMyoD mRNA. XMyoD protein accumulates in nuclei of the future somitic mesoderm from the middle of gastrulation. In neurulae and tailbud embryos it is expressed specifically in the myotomal cells of the somites. XMyoD is in the nucleus of apparently every cell in the myotomes. It accumulates first in the anterior somitic mesoderm, and its concentration then declines in anterior somites from the tailbud stage onwards.

This article provides a brief account of the career of Eugenia M. del Pino. Casual events and serendipity played important roles in modeling her career as developmental biologist. In collaboration with colleagues and students, she analyzed the biology and development of the marsupial frog Gastrotheca riobambae (family: Hemiphractidae) in comparison with Xenopus laevis and tropical frogs. The emphasis was placed on oogenesis and the early stages of development. Topics include the mono- and multi-nucleated modes of oogenesis. She described two modes of gastrulation in frogs, gastrulation modes one and two according to the timing of notochord elongation. She was able to establish a pioneer laboratory for the comparative analysis of frog development in Ibero America at the Pontifical Catholic University of Ecuador, in Quito. Her contributions to society include her influence in the establishment of the National Academy of Sciences of Ecuador, and efforts toward the conservation of the Galápagos Archipelago. She is part of a pioneer group of professors that placed Biology as an academic discipline in Ecuador. The experiences of her career reveal that we all face difficulties in our jobs. However, nothing is impossible when we follow a passion. Her work reveals that the key to success is to turn obstacles into opportunities.
