Programmed cell death and heterolysis of larval epithelial cells by macrophage‐like cells in the anuran small intestine in vivo and in vitro
The degenerative processes in the larval small intestine of Xenopus laevis tadpoles during spontaneous metamorphosis and during thyroid hormone‐induced metamorphosis in vitro were examined byExpand

Connective tissue is involved in adult epithelial development of the small intestine during anuran metamorphosis in vitro
SummaryThe role of connective tissue in metamorphic changes of the small intestinal epithelium inXenopus laevis tadpoles was investigated by using organ culture techniques and electron microscopy.Expand

Induction of metamorphosis by thyroid hormone in anuran small intestine cultured organotypically in vitro
SummaryWe have developed an organ culture system of the anuran small intestine to reproduce in vitro the transition from larval to adult epithelial form which occurs during spontaneous metamorphosis.Expand

Development of the connective tissue in the digestive tract of the larval and metamorphosing Xenopus laevis.
Developmental changes, until the completion of metamorphosis, of the connective tissue of the digestive tract in the South African clawed frog Xenopus laevis were examined by light and scanningExpand

Changes in lectin‐binding pattern in the digestive tract of Xenopus laevis during metamorphosis. I. Gastric region
The distribution of structural and secretory glycoconjugates in the gastric region of metamorphosing Xenopus laevis was studied by the avidin‐biotinperoxidase (ABC) histochemical staining methodExpand

Phagocytotic cells in the fish heart.
Comparatively little is known about host-defense activities in the fish heart. Investigations showed that intraperitoneally injected carbon particles are actively taken up by the cardiac endothelialExpand

Incilaria mucus agglutinated human erythrocytes.
The body surface mucus from the land slug, Incilaria fruhstorferi, not only opsonized sheep red blood cells (SRBC) and agglutinated human types A and B erythrocytes (HRBC) but also caused hemolysisExpand

Melano-macrophage centre-like structure in the heart of the medaka, Oryzias latipes.
Endocardial lining cells in the heart of certain teleosts are phagocytic against foreign materials. In the medaka Oryzias latipes, in addition to the endocardial lining cells, cells in theExpand

Ultrastructural changes in the intestinal connective tissue of Xenopus laevis during metamorphosis
Ultrastuctural changes in the intestinal connective tissue of Xenopus laevis during metamorphosis have been studied. Throughout the larval period to stage 60, the connective tissue consists of a fewExpand
