Xenopus laevis larvae were kept in containers of 0,4 liters on different backgrounds
(white, gray and black). The containers were kept in a closed box with artificial white
light for 12 hours a day at 24 оС����������������������������������������������������������. Observations were carried out daily with a focus on pigmentary
cells number on a lateral part of the animals’ trunk. The authors differentiate two
periods in pigmentary cells development at the early stages. The first one lasts from the
moment of hatching up to 45th stage. During this period there are only differentiations of
melanophores from melanoblastes. The second period begins at 47th stage when separate
mitoses take place. The study assesses the role of mitoses and differentiations for dermal
melanophores number dynamics of animals that were kept on different backgrounds. For
the first time, the authors reveal the influence of a background on the morphological reaction
of pigmentary cells at the early stages of X. laevis development.
