Elegans zygote embarks on an invariant cell lineage to generate all somatic tissue plus two germline stem cells (gscs). Gscs subsequently divide variably to make the germline tissue during larval development and to maintain it in adults (kimble and hirsh, 1979;.
For the first time, cell lineage analyses have been carried out for an indirect‐developing representative of the enteropneust hemichordates, pty‐ chodera flava. Single blastomeres were iontophoretically labeled with dii at the 2‐ through 16‐cell stages, and their fates followed through development to the tornaria larval stage.

The study of the cleavage and early larval history of fiona marina.
A variety of genetic techniques have been devised to determine cell lineage relationships during tissue development. Some of these systems monitor cell lineages spatially and/or temporally without regard to gene expression by the cells, whereas others correlate gene expression with the lineage under study. The gal4 technique for real-time and clonal expression (g-trace) system allows for rapid.
During early development, patterns of cell division-embryonic cleavage-accompany the gradual restriction of blastomeres to specific cell fates. In spiralia, which include annelids, mollusks, and flatworms, spiral cleavage produces a highly stereotypic, spiral-like arrangement of blastomeres and swimming trochophore-type larvae with rotational.
The early cell lineages of indirect-developing species generate the cells that produce these larval forms. These larvae feed and grow; thus, the eggs that produce them are relatively small. Only a few cell cleavage cycles are needed to produce the requisite cells and initiate larval morphogenesis.
The results suggest that adaptation has played a significant role in the evolution of cell cell lineage and fate specification in early embryos; however.

The cell lineage of several annelids has been described in detail, and every cell in the early stage embryo of capitella and chaetopterus can be uniquely identified. In addition, the fates of these cells are known and a comprehensive fate map that identifies the early embryonic origin of larval features is available for capitella.
Cell lineage and cell fates are correlated, such as cae- norhabditis elegans or the nervous present at high levels in early larvae and low levels in late larvae.

The apical organ of ciliated larvae of cnidarians and bilaterians is a true larval organ that disappears before or at metamorphosis. It appears to be sensory, probably involved in metamorphosis, but knowledge is scant. The ciliated protostome larvae show ganglia/nerve cords that are retained as the adult central nervous system (cns).

Of the marine annelid platynereis dumerilii reveal highly stereotypical development and an invariant cell lineage of early differentiating cell types.
Teleta embryos and early larval stages develop in a brood tube that surrounds the mother. Over the course of approximately a week, the embryos develop into non-feeding larvae which form musculature, a centralized nervous system, two circular ciliary bands, two eye spots, segments, and setae.
The caenorhabditis elegans embryo undergoes a series of stereotyped cell cleavages that generates the organs and tissues necessary for an animal to survive. Here we review two models of embryonic patterning, one that is lineage-based, and one that focuses on domains of organ and tissue precursors. Elegans embryogenesis suggests that this animal develops by mechanisms.
Thyroid hormone (th) signaling promotes tissue maturation and adult organ formation. Developmental transitions alter an organism's metabolic requirements, and it remains unclear how development and metabolic demands are coordinated. We used the zebrafish as a model to test whether and how th signaling affects pancreatic islet maturation, and consequently glucose homeostasis, during the larval.

In non-clitellate annelids (errantia, sedentaria, and early branching), the number of larval segments is variable, and many more are added in post-larval development: in nereidids (errantia) such as platynereis, only three larval segments develop, while in capitella (sedentaria), 13 larval segments (thamm and seaver, 2008) and in chaetopterus.

In tribolium, germline proliferation is restricted to larval and early pupal stages, whereas the fsc niche remains active up to adulthood thus, the formation and maintenance of the follicle stem cell (fsc) linage in tribolium is largely independent of the germline stem cells (gscs).
A classical example of such cell groups is the imaginal discs, clusters of cells in the larva determined to form specific regions of the adult. Because the discs cannot be identified in early stages during embryogenesis, their origin and early development can best be studied using cell lineage techniques such as mitotic recombination.
The widespread occurrence of this pattern of early development attests to its tremendous evolutionary success. Despite the large degree of conservation in the spiral cleavage pattern and other basic aspects of early development, changes in cell fate maps and in the mechanisms of blastomere specification have arisen.
The cell lineage relationships among embryo, larva, and adult sea urchins have not been investigated to date because of technical difficulties, but it is important to clarify these relationships. The presence of an early larval skeleton is one of the specific defining characteristics of echinoids.
The larval body is built by embryonic cells having limited division capacity, and differentiation is specified by signals between individual cells.
Two theories for this larval type have been prevalent, the trochaea theory and the theory proposed by ivanova-kazas. The embryology, or more precisely the cell-lineage, of these larvae seems to be central for our understanding of their origin, but important details have been missing.
The developmental strategies of embryos within the various taxa of polychaetes are designed to set up the fate of the cell lines. Some of these traits of pattern formation are considered to be ancestral, but we also find a number of derived developmental characteristics, some of which might be useful indicators for phylogenetic relationships.
We conclude that type ii neuroblasts change molecular profile over the course of their 120 hr long larval cell lineage, with a striking early-to-late transition from chinmo/imp/lin-28 to broad/syncrip/e93 at ~60 hr, midway through their lineage.
