[Morphological transformation of sensory ganglion neurons and satellite cells].
Sensory ganglion neurons in higher vertebrates are unique in that they are pseudounipolar with a single stem process that divides at some distance from the cell body into central and peripheral processes. In the early stages of development, these neurons are bipolar but later they became pseudounipolar. This developmental process of sensory ganglion neurons with satellite cells was examined by ...
متن کاملPrimordial germ cells migration: morphological and molecular aspects
Primordial germ cells (PGCs) are germline stem cells that give rise to gametes in vertebrates. They originate outside the embryo very early in development and migrate by a well-defined route into the genital ridges. During early embryogenesis in mammals, the PGCs are observed in an extra-embryonic region near the yolk sac, translocate to the endodermal epithelium of the hindgut as embryogenesis...
متن کاملMorphological Aspects of Ciliary Motility
In Elliptio complanatus lateral cilia, two distinct patterns of filament termination can be discerned. In one case, all nine filaments are present and all are single; in the second, at least one filament is missing but doublets are still present. These probably represent different configurations within one cilium in different stroke positions; to get from one to the other, some peripheral filam...
متن کاملSome Morphological Aspects of Configurations
In the present paper, to begin with, the attention is focused on a number of basic characteristics of the configurations. These characteristics concern such morphological aspects as ‘curviance’ and ‘connectivity’. The term ‘curviance’ means the ‘way in which a configuration is curved’ and the term ‘connectivity’ means the ‘way in which the components of a configuration are interrelated’. The mo...
متن کاملDifferentiation of human embryonic stem cells into neurons
Human embryonic stem (ES) cells are undifferentiated pluripotent cells derived from the inner cell mass of blastocyst stage embryos. These unique cell lines have the potential to form virtually any cell type in the body and can be propagated in vitro indefinitely in an undifferentiated state. These cells are capable of forming embryoid bodies (EB) that contain cells from all three embryonic lin...
