Newborn mice have a lower spontaneous resistance to the growth of a syngeneic plasmacytoma (MOPC-460) as compared to adult mice. The transfer of different leucocyte populations from non-immunized adult donors to newborn mice influence in a dual way the resistance to MOPC-460 growth, depending on the number of cells transferred. The transfer of a low number of neutrophils, thymus or spleen cells enhances the MOPC-460 takes. Higher numbers of neutrophils, thymus or bone marrow cells induce an effective protenction. By contrast, macrophages over a dose of 1 X 10(4) constantly produce a reduction of tumour growth.
与成年小鼠相比,新生小鼠对同基因浆细胞瘤(MOPC-460)生长的自发抵抗力较低。将未免疫成年供体的不同白细胞群体转移到新生小鼠体内,根据转移细胞的数量,以双重方式影响对MOPC-460生长的抵抗力。转移少量中性粒细胞、胸腺或脾细胞可增强MOPC-460的接种成功率。较高数量的中性粒细胞、胸腺或骨髓细胞可诱导有效的保护作用。相比之下,超过1×10⁴剂量的巨噬细胞会持续导致肿瘤生长减少。
