Current Opinion in Plant Biology, 1999
Organogenesis in vitro consists of many aspects such as phytohormone perception, dedifferentiation of differentiated cells to acquire organogenic competence, re-entry of quiescent cells into cell cycle, and organization of cell division to form specific organ primordia and meristems.

Annual Review of Immunology, 2008
The epithelial architecture of the thymus fosters growth, differentiation, and T cell receptor repertoire selection of large numbers of immature T cells that continuously feed the mature peripheral T cell pool. Failure to build or to maintain a proper thymus structure can lead to defects ranging from immunodeficiency to autoimmunity.

Evolution of thymus organogenesis
Developmental & Comparative Immunology, 2013The thymus is the primary organ for functional T lymphocyte development in jawed vertebrates. A new study in the jawless fish, lampreys, indicates the existence of a primitive thymus in these surviving representatives of the most ancient vertebrates, providing strong evidence of co-evolution of T cells and thymus.

Organogenesis for kidney regeneration
Current Opinion in Organ Transplantation, 2013The kidney has an elaborate and complicated structure comprising several cell types. Damage or destruction of the kidney thus necessitates reconstruction of all the component cell types to regenerate a functional three-dimensional renal structure. Therefore, despite all the recent advances in our understanding and technical approaches to stem cell and ...

Lymphoid Organogenesis in the Intestine
Immunologic Research, 2005Lymphoid organogenesis is dependent upon a series of intricate cellular interactions involving adhesion molecules, chemokines, and cytokines that generate fully compartmentalized lymphoid structures. Development of organized lymphoid structures in the intestine begins prenatally and continues through adulthood, with constant adaptations to changes in ...

Organogenesis of the vertebrate heart
WIREs Developmental Biology, 2012AbstractOrganogenesis of the vertebrate heart involves a complex sequence of events initiating with specification and differentiation of myocardial and endocardial cells in anterior lateral mesoderm shortly after gastrulation, followed by formation and rightward looping of the early heart tube.

MicroRNAs in Organogenesis and Disease
Current Molecular Medicine, 2008Large numbers and quantities of different, small RNA molecules are present in the cytoplasm of animal and plant cells. One subclass of these molecules is represented by the noncoding microRNAs. Since their discovery in the 1990s a multitude of basic information has accumulated, which has identified their function in post-transcriptional control, either

Organogenesis of the colon in rats
Journal of Morphology, 1980AbstractColonic organogenesis in rats was studied using light microscopic techniques for the demonstration of mucosubstances, glycogen, and connective tissue fibers.Crypts began as intraepithelial spaces which were in continuity with the colonic lumen.

Micropropagation of Poinsettia by Organogenesis
2009Poinsettia (Euphorbia pulcherrima) is one of the most popular ornamental pot plants. Conventional propagation is by cuttings, generally focused on a period prior to the most intensive time of sales. Rapid multiplication of elite clones, the production of pathogen-free plants and more rapid introduction of novel cultivars (cvs.) with desirable traits ...
