[The origin of elementary units of multicellularity and development of a spatial organization of cell layers]

Autor: G A, Savost'ianov

Publikováno v: Izvestiia Akademii nauk. Seriia biologicheskaia. (2)

The concept of the elementary unit of multicellularity, the histion, which also serves as a morphofunctional unit of cell layers, is introduced. Histions are cell groups formed as a result of division of labor between cells. Cell layers are regarded

[Modeling of processes of specialization and integration as a basis for development of multicellularity]

Autor: G A, Savost'ianov

Publikováno v: Zhurnal evoliutsionnoi biokhimii i fiziologii. 46(6)

The formalized description of the procedure of division of labor as the most important invariant of progressing development is presented. The concept of histion is introduced--the element of the elementary unit that arises as a result of such divisio

[Towards the computational three-dimensional histology. Application of computer models to the reconstruction of the three-dimensional structure of the biological tissue with the sensory cochlear acoustic epithelium in birds as an example]

Autor: E G, Savost'ianova, A V, Vorob'ev, N M, Grefner, V F, Levchenko, G A, Savost'ianov

Publikováno v: Morfologiia (Saint Petersburg, Russia). 131(1)

This article presents new efficient method of 3-D structure reconstruction of epithelia. In contrast to existing empirical approaches, this method is based on the use of the families of topological and geometrical models of tissue structure, obtained

[Theory of spatial organization of epithelial layers (using neuroepithelia as an example)]

Autor: G A, Savost'ianov

Publikováno v: Morfologiia (Saint Petersburg, Russia). 120(5)

New principles of spatial organization of epithelial layers and highly productive approach for studying their tridimensional histoarchitecture have been proposed for the first time. This approach was based on conception of module structure of tissues

[Principles of spatial organization of cellular sheets]

Autor: G A, Savost'ianov

Publikováno v: Biofizika. 46(3)

The principles of the spatial organisation of epithelial sheets are described, and a new approach to studying their histoarchitecture is proposed. The approach is based on the concept of modular structure of tissues and consists in constructing a fam

[The 3-dimensional organization of the sensory epithelium of the cochlea in birds]

Autor: G A, Savost'ianov, N M, Grefner, T B, Golubeva, E G, Savost'ianova

Publikováno v: Morfologiia (Saint Petersburg, Russia). 117(2)

Using authors' original approach to studying histoarchitecture of cellular layers three-dimensional structure of bird helix sensory epithelium was studied theoretically and experimentally. The composition of its elementary morphofunctional unit, AB3

[Modelling of the 3-dimensional structure of the epithelia, constructed of bi-, tri and tetracellular modules]

Autor: G A, Savost'ianov

Publikováno v: Morfologiia (Saint Petersburg, Russia). 113(2)

A new approach for studying 3-dimensional histoarchitectonics of cellular layers is suggested. It is based on (1) development of theoretical concepts on module structure of tissues; (2) working out topological and geometrical models of tissue structu

[Three-dimensional histoarchitectonics of the larval epidermis of the grass frog]

Autor: G A, Savost'ianov, N M, Grefner

Publikováno v: Ontogenez. 29(1)

We have conducted theoretical and experimental study of the three-dimensional structure of epidermis in the larva of the grass frog. Three-dimensional modeling of cell shape and mutual arrangement yielded several variants of cell-to-cell connections
