Changes in elemental and isotopic composition accompanying larval growth and metamorphosis of the moor frog

Yu. K. Doronin, A. V. Tiunov, E. N. Kalistratova

Russian Journal of Developmental Biology > 2017 > 48 > 1 > 41-48

A variety of early ontogenetic events of anuran species (growth, structural and biochemical diversification, metamorphosis) offers a unique opportunity to evaluate the effectiveness and application limits of mass spectrometry method for the analysis of metabolic and transformation events in developing organisms. The dynamics of relative carbon and nitrogen contents and stable isotopes of these elements...

Redox potential kinetics of the incubation medium during early development stages of Misgurnus fossilis loach

A. B. Burlakov, V. I. Kuzmin, A. F. Gadzaov, D. L. Tytik, więcej

Russian Journal of Developmental Biology > 2017 > 48 > 1 > 23-33

The analysis of kinetic curve of redox potential changes (ORP) of aqueous medium in the process of loach embryo population development at 17°C was conducted. The system of critical points defining periodization of the major stages of embryo development was identified on the ORP curve in the time interval up to τ₀ using novel methods for processing of nonlinear signals. It was shown that τ₀ was a natural...

On the work of the developmental biophysics laboratory of the embryology department of Moscow State University

L. V. Beloussov

Russian Journal of Developmental Biology > 2017 > 48 > 1 > 1-4

The laboratory is engaged in morphomechanics—the study of self-organization of mechanical forces that create the shape and structure of the embryonic primordia. As part of its work, the laboratory described pulsating modes of mechanical stresses in hydroids, identified and mapped mechanical stresses in the tissues of amphibian embryos, and studied morphogenetic reorganization caused by the relaxation...

Regeneration of the skin pigment system during larval development of the clawed frog

A. Yu. Molchanov, O. V. Burlakova, V. A. Golichenkov

Russian Journal of Developmental Biology > 2017 > 48 > 1 > 75-80

We demonstrate regeneration capability of the skin pigment system of clawed frog larvae after local damage to melanophores without skin rupture. The contribution to recovery of pigmentation of the injured area of de novo differentiation of melanophores is compared to contribution of mitotic division of undamaged melanophores localized on the boundaries of the injured area. The regeneration process...

Blastocyst hatching in humans

R. A. Shafei, A. G. Syrkasheva, A. Yu. Romanov, N. P. Makarova, więcej

Russian Journal of Developmental Biology > 2017 > 48 > 1 > 5-15

The human oocyte is surrounded by the zona pellucida—an elastic, transparent extracellular matrix consisting of specific glycoproteins. The zona pellucida is preserved after fertilization and surrounds the developing human embryo for a few days. The embryo needs to get out of the zona pellucida before implantation to establish cell contacts between the trophectoderm and endometrial epithelium. The...

Use of fundamental properties of embryonic objects for studying potential environmental effects of technogenic impacts

O. P. Melekhova

Russian Journal of Developmental Biology > 2017 > 48 > 1 > 65-74

This article analyzes the problems of biosafety in terms of individual development patterns. Previously, the key role of epigenetic free radical processes in normal embryonic development of lower vertebrates in the formation of the competence and determination of embryonic primordia has been demonstrated, and a significant increase in the intensity of free radical process before every qualitative...

Efficiency of cell transplantation in repair of mouse liver damage

E. S. Korobko, E. A. Suprunenko, A. V. Vasil’ev

Russian Journal of Developmental Biology > 2017 > 48 > 1 > 49-55

The effectiveness of two transplantation methods of human hepatocellular carcinoma cells HepG2 and allogeneic mesenchymal stromal cells of adipose tissue (AT MSCs) into mice was compared in order to select the most effective for liver damage repair. Considerable advantage of cell transplantation into the spleen compared with intraperitoneal administration was shown. It is found that, under similar...

Role of mechano-dependent cell movements in the establishment of spatial organization of axial rudiments in Xenopus laevis embryos

D. V. Bredov, A. U. Evstifeeva

Russian Journal of Developmental Biology > 2017 > 48 > 1 > 16-22

Trajectories of individual cell movements and patterns of differentiation in the axial rudiments in suprablastoporal areas (SBA) in whole embryos of Xenopus laevis artificially stretched in the transverse direction up to 120–200% from the initial length at the early gastrula stage were mapped. We observed the impairment of anisotropic cell movements of longitudinal stretching and latero-medial convergence...

Cellular model based on laser microsurgery of cell spheroids to study the repair process

N. V. Kosheleva, I. V. Ilina, K. V. Kozhina, I. M. Zurina, więcej

Russian Journal of Developmental Biology > 2017 > 48 > 1 > 56-64

In this study, modern techniques of laser microsurgery of cell spheroids have been used to develop a new simple, reproducible model for studying the mechanisms of repair and regeneration in vitro. Nanosecond laser pulses were applied to perform a microdissection of the outer and the inner zones of the spheroids from dermal fibroblasts. To achieve effective dissection and preservation of spheroid viability,...

Effects of mechanical stretching of embryonic tissues on axial structure formation in Xenopus laevis

Yu. I. Vasilegina, S. V. Kremnev, D. A. Nikishin

Russian Journal of Developmental Biology > 2017 > 48 > 1 > 34-40

Effect of mechanical stretch on the differentiation of axial anlages and Chordin gene expression was studied in sandwich explants prepared from embryonic tissues of Xenopus laevis at the early gastrula stage in two variants: with dissected or intact dorso-medial region. In the first case, convergent cell movements were suppressed and properly organized axial organs (notochord and somites) were almost...
