脊椎动物胚胎的两个区域,血岛和背侧板(DLP),参与早期造血发育。在非洲爪蟾中,原始红细胞仅来源于腹侧血岛(VBI),而永久造血细胞(如淋巴细胞)来源于VBI和DLP。我们利用移植技术在体内证明所有造血细胞(胚胎、胎儿或成人)均来源于腹侧中胚层。VBI和DLP之间的相互移植表明,这两个地区是双潜能的原始和永久性造血。VBI对原始红细胞生成的承诺和DLP对确定性造血的限制发生在神经胚阶段。因此,造血发育涉及胚胎腹轴上血液程序的诱导,随后是环境调节的原始或定型谱系的特化。
Two regions of the vertebrate embryo, the blood islands and the dorsal lateral plate (DLP), participate in early hematopoietic development. In Xenopus, primitive erythrocytes are derived solely from the ventral blood islands (VBI), while definitive hematopoietic cells such as lymphocytes are derived from both VBI and DLP. We have utilized a transplantation technique to demonstrate in vivo that all hematopoietic cells (embryonic, fetal, or adult) originate from ventral mesoderm. Reciprocal grafts between VBI and DLP demonstrated that both regions are bipotential with respect to primitive and definitive hematopoiesis. Commitment of the VBI to primitive erythropoiesis and restriction of the DLP to definitive hematopoiesis occurs during neurula stages. Thus, hematopoietic development involves the induction of the blood program on the ventral axis of the embryo followed by environmentally regulated specification to the primitive or definitive lineages.
