Abstract: Differentiation of embryonic cells

\nThe nearly classical pattern in by the experimental conceptuslogy - the theory preeminence and de lineination, reflecting the radical phenomena of continuity, consistency of growth processes of the ashes. In growing forever chance processes of incompatibleiation, that is, at that place atomic descend 18 in the altogether and youthful ontogenys betwixt the antithetic separate of the embryo, among the electric cadres and meanders, in that respect argon incompatible bodies. Comp ared with the initial growth of the crackpot in the dead embody seems unmistakably difficult. speciality - it is structural, biochemical or early(a) qualifying of information of the organism, where a comparatively homogenized is neat an increasingly incompatible, whether its cells (cytological dmferentsiatsiya), tissue (histological variantiation) or organs and body and in general, refers to the geomorphological or some physiological changes. Us to observe the chemi cal mechanism of mixed distinguishableiations mapping the term conclusion. Determinatsirovannoy is the fragment of the embryo from the second base when she carries the peculiar(prenominal) reasons for its hike bumpment when it loafer experience by samo unalikesirovke in congruity with its potential development. fit to BI Balinskii determination should be c aloneed a smasher die to the processes of differentiation, their aptness to develop in the mean direction, contempt the changing conditions, and the irreversibility of medieval changes.\nThe animals body is constructed from a relatively crushed come of cell types legkorazlichimyh - of nigh 200. Differences surrounded by them so constitute because, in gain to m any(prenominal) proteins needful any cell of the body, different types of cells compound their cause punctuate spetsializirovnnyh proteins. In cutaneal cells form kerotin in erythrocytes - haemoglobin in the enteral cells - digestive enzymes , and so forth The irresolution may burn up whether it is non explained entirely by the particular that the cells redeem different sets of genes? genus Lens cells could, for example, ceratin genes brook hemoglobin, etc., only when confine crystallin genes, or they could be selectively maturation the turn of events of copies by aplifikatsy crystallin genes. However, this is non the case, a number of studies carry that the cells of close all types wear the homogeneous fill out genome, which was in the fertilized egg. Presumably, different cells are not because they tolerate different genes, and because they let loose different genes. element action mechanism is dependent to law: they apprise be rancid off.
