"Spontaneous" sex reversal in organ cultures of the embryonic male gonad of the bird.
The left embryonic testis of the bird (4-8 days of incubation) was organ cultured in medium that contained 10% foetal calf serum. Under these conditions, the germinal epithelium (GE) of the 4-day gonad differentiates into an ovarian cortex and the male primordial germ cells (PGCs) complete a developmental sequence similar to normal oocytes, i.e. they divide mitotically, develop a Balbiani body,...
متن کاملDevelopment of Fetal Thymocytes in Organ Cultures
When mature thymus-derived (T) lymphocytes from peripheral lymphoid organs are activated by antigen or mitogen, an increase in the expression of the surface receptor for interleukin 2 (IL-2-R) is observed that precedes the development of effector function (1-3). While IL-2 is known to be a specific growth factor for such mature T cells (4, 5), it is not known whether IL-2 is also involved as a ...
متن کاملPrimary Antibody Response in Organ Cultures
Specific antibody formation has been elicited in vitro following antigenic stimulation by either sheep (in a total of 472 of 875 cultures) or chick erythrocytes (in 65 of 135 cultures tested). The response was manifested by mouse spleen and lymph node explants whereas thymus cultures were inactive. The reaction has been characterized as a primary immune response in view of its kinetics as compa...
متن کاملUsing elicitors for enhanced production of secondary metabolites in plant cell and organ suspension cultures
In biotechnology has been concentrated to review alternative routes for the production of natural compounds. Plant cell culture systems are viable alternatives for the production of secondary metabolites that are of commercial importance in food and pharmaceutical industries. However, relatively very few cultures synthesize these compounds over extended periods in amounts comparable to those fo...
