本文用流式细胞术定量分析了非洲爪蟾淋巴细胞的胚胎起源。在从神经板到尾芽阶段的相同发育阶段的二倍体(2N)和三倍体(3 N)胚胎之间进行头/体相互移植。胸腺和脾脏从变性后的嵌合体中取出。细胞悬浮液用荧光DNA染色剂光神霉素染色,然后通过流式细胞术测定细胞的倍性(相对荧光强度)。嵌合体中的所有淋巴细胞均来自胚胎的后部。在其他实验中,侧板或腹侧中胚层的各个区域从三倍体移植到二倍体胚胎。只有包括背中胚层的移植物才产生淋巴细胞。
Quantitative flow cytometry was used to examine the embryonic origin of lymphocytes inXenopus laevis. Reciprocal head/body transplants were made between diploid (2N) and triploid (3N) embryos of the same developmental stages ranging from neural plate to tail bud stages. Thymuses and spleens were removed from postmetamorphic chimeras. Cell suspensions were stained with the fluorescent DNA stain, mithramycin, and the ploidy (relative fluorescence intensity) of the cells was then determined by flow cytometry. All lymphocytes in the chimeras were derived from the posterior portion of the embryo. In other experiments, various regions of the lateral plate or ventral mesoderm were grafted from triploid to diploid embryos. Only transplants that included middorsal mesoderm gave rise to lymphocytes.
