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 ...

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.

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.

Early organogenesis of the kidney
Pediatric Nephrology, 1987The mammalian permanent kidney consists of three cell lineages of different origin: the epithelial cells of the ureter bud, the mesenchymal cells of the nephric blastema and the endothelial cells of the capillaries. Organogenesis is governed by a cascade of morphogenetic interactions between these cell populations, a reciprocal epithelial-mesenchymal ...

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.

AbstractOur understanding of vertebrate salivary gland organogenesis has been largely informed by the study of the developing mouse submandibular gland (SMG), which will be the major focus of this review. The mouse SMG has been historically used as a model system to study epithelial–mesenchymal interactions, growth factor–extracellular matrix (ECM ...

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 ...

Organogenesis of lymphoid tissues
Nature Reviews Immunology, 2003The development of lymphoid organs depends on the correct expression of several molecules within a defined timeframe during ontogeny. Although this is an extremely complex process, with each secondary lymphoid tissue requiring subtly different signals, a common framework for lymphoid development is beginning to emerge. Drawing on studies of lymph nodes,
