[T-lymphocyte reactivity in inbred mice during pregnancy].

Blast-transformation of lymphocytes of pregnant and control mice of three lines was studied after their in vitro stimulation with phytohemaglutinin. There was no significant difference between lymphocyte transformation in pregnant and control mice, and the blood sera of pregnant animals do not inhibit blast-transformation. The responsiveness of CBA strain lymphocytes was higher than that of BALB/C and C57BL strains.
