[Myelopoiesis in lymph nodes of mice treated with trypan blue (author's transl)]. 1978

P Sesma

When mice are injected with trypan blue inside the peritoneal cavity immediately after birth, a delay of the lymphocyte colonization and an enhancement of the lymph node myelopoiesis are observed. In normal mice some granulopoiesis takes place in lymph nodes between 4th and 12th days after birth, but after trypan blue treatment granulopoiesis increases and erythroid colonies appear. These findings indicate that the blockade of RES enhances the hemopoiesis in lymph nodes.

D007274	Injections, Intraperitoneal	Forceful administration into the peritoneal cavity of liquid medication, nutrient, or other fluid through a hollow needle piercing the abdominal wall.	Intraperitoneal Injections,Injection, Intraperitoneal,Intraperitoneal Injection
D008198	Lymph Nodes	They are oval or bean shaped bodies (1 - 30 mm in diameter) located along the lymphatic system.	Lymph Node,Node, Lymph,Nodes, Lymph
D004920	Erythropoiesis	The production of red blood cells (ERYTHROCYTES). In humans, erythrocytes are produced by the YOLK SAC in the first trimester; by the liver in the second trimester; by the BONE MARROW in the third trimester and after birth. In normal individuals, the erythrocyte count in the peripheral blood remains relatively constant implying a balance between the rate of erythrocyte production and rate of destruction.	Erythropoieses
D006098	Granulocytes	Leukocytes with abundant granules in the cytoplasm. They are divided into three groups according to the staining properties of the granules: neutrophilic, eosinophilic, and basophilic. Mature granulocytes are the NEUTROPHILS; EOSINOPHILS; and BASOPHILS.	Granulocyte
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
