Expression of TNF-alpha in pig fetal cells stimulated in vitro.
Macrophages and lymphocytes of pig fetuses stimulated in vitro with bacterial mitogens such as lipopolysaccharide and Nocardia opaca delipidated cell mitogen showed a high TNF-alpha cytoplasmic expression. TNF-alpha was detected by immunofluorescence in peripheral blood lymphocytes and lymphocytes from the thymic region as early as at 34 d of gestation. Macrophages were the main producers of TNF-alpha at later developmental stages.
