Much of the specification for the basic embryonic body plan is the result of a hierarchy of developmental decisions at different developmental times. The extracellular matrix (ECM) appears to be a very dynamic structure during embryogenesis. One of the mesenchymal ECM proteins, tenascin, is reported to be transiently expressed during embryonic tissue(More)
BACKGROUND The exact biological function of CD30 in the thymus during development has been only partially elucidated, although data indicate it may be involved in negative selection. This study was prompted by the observation of a positive reaction of thymic epithelial cells (TECs), Hassall's corpuscles, and thymocytes with the monoclonal antibody CD30(More)
In an initial period of vertebrate phylogeny (bone marrow-less vertebrates), lymphohaematopoiesis takes place in numerous organs containing a suitable microenvironment. Among other organs (i.e., gonads, kidney and spleen), the liver is apparently the most appropriate site for homing and differentiation of haematopoietic cell precursors. Interaction between(More)
