Biology Department, Nanjing University.

The pre-embedding immunoelectron microscopic method was used to study the development of antibody-producing cells in the guinea pig popliteal lymph nodes of 2, 3, 5, 8 and 10 days after a second challenge with horseradish peroxidase. The results indicated that the antibody activity was located in the perinuclear space, the endoplasmic reticulum and Golgi complex. According to the cellular developmental stages and the characteristics of distribution of the antibody activity, the antibody-producing cells (APC) were divided into four types: (1) Type I cells (lymphocytes) exhibited many positive granules throughout the cytoplasm; (2) Type II cells (proplasmacytes) contained many positive granules and positive short bars, some of them were parallel; (3) Type III cells (proplasmacytes) contained numerous parallel positive lamellae in cytoplasm; (4) the parallel lamellae in cytoplasm of type IV cells (plasmacytes) were arranged into a network-endoplasmic reticulum. According to the kinetic change from granules, short bars to parallel lamellae and the network, the results indicated the developmental course of AFC from lymphocytes, proplasmacytes to plasmacytes.

D006168	Guinea Pigs	A common name used for the genus Cavia. The most common species is Cavia porcellus which is the domesticated guinea pig used for pets and biomedical research.	Cavia,Cavia porcellus,Guinea Pig,Pig, Guinea,Pigs, Guinea
D006735	Horseradish Peroxidase	An enzyme isolated from horseradish which is able to act as an antigen. It is frequently used as a histochemical tracer for light and electron microscopy. Its antigenicity has permitted its use as a combined antigen and marker in experimental immunology.

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.

D000921	Antibody-Producing Cells	Cells of the lymphoid series that can react with antigen to produce specific cell products called antibodies. Various cell subpopulations, often B-lymphocytes, can be defined, based on the different classes of immunoglobulins that they synthesize.

D016253	Microscopy, Immunoelectron	Microscopy in which the samples are first stained immunocytochemically and then examined using an electron microscope. Immunoelectron microscopy is used extensively in diagnostic virology as part of very sensitive immunoassays.
