Proper innervation of peripheral organs helps to maintain physiological homeostasis and elicit responses to external stimuli. Disruptions to normal function can result in pathophysiological consequences. The establishment of connections and communication between the central nervous system and the peripheral organs is accomplished through the peripheral

Cellular and Molecular Life Sciences CMLS, 1997
Our search for an angiogenesis-inducing factor in culture medium conditioned by human colon adenocarcinoma cells (HT-29) was inspired by the 'organizer' hypothesis originally postulated by Spemann. It led us to the isolation of angiogenin, a 14 kD protein homologous to pancreatic ribonuclease and one of the most potent stimulators of blood vessel ...

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.

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.

Cardiovascular disease is the number one cause of death in the United States. Despite the benefits of current treatments, many patients do not regain full cardiac function following myocardial infarction. Cardiac tissue–engineered products consisting of biological or synthetic scaffolds, with or without cellular and/or molecular components, are ...

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.

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 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.

Organogenesis: variations on a theme
Trends in Genetics, 2015In the most basic sense, an organ represents the coordination of similar cells to accomplish a specific function. Ranging in complexity from the simple tube-shaped heart of Ciona to the uncharted intricacies of the human brain, organs display immense variety in their size, shape, and function.
