The gastric autonomic innervation of the dogfish was examined for regulatory peptides and serotonin by immunochemical techniques. Bouin's-fixed, paraffin-embedded or benzoquinone-fixed frozen sections were used for light microscopical immunocytochemistry and glutaraldehyde-fixed resin-embedded sections for electron microscopical immunocytochemistry.(More)
The demonstration of the presence of dividing primitive cells in damaged hearts has sparked increased interest about myocardium regenerative processes. We examined the rate and the differentiation of in vitro cultured resident cardiac primitive cells obtained from pathological and normal human hearts in order to evaluate the activation of progenitors and(More)
Fibroblasts are involved in all pathologies characterized by increased ExtraCellularMatrix synthesis, from wound healing to fibrosis. Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF) is a cytokine isolated as an hemopoietic growth factor but recently indicated as a differentiative agent on endothelial cells. In this work we demonstrated the(More)
This study reports some morphological characteristics of human placenta that play an important physiological role in normal pregnancies. The structures were the spiral arteries, the extracellular matrix and the MHC-antigens bearing cells. We studied these important tissue compartments in 80 placentas from normal and abnormal pregnancies (affected by in(More)
Physical activity increases the work load of the heart. The adjustments of the heart depend on the quality and quantity of the work performed. These adjustments concern the function and the morphology of the cardiovascular system. It is important to underline that these adjustments are not permanent and can disappear when physical activity is stopped. In(More)
We collected human fetal and adult normal meninges to relate the age of the tissue with the presence of collagenous and non-collagenous components of Extra Cellular Matrix (ECM). Immunohistochemistry led us to observe some differences in the amount and in the distribution of these proteins between the two sets of specimens. In particular, laminin and(More)
