4、d-Loxp-EGFP)和TG(zC-myb:EGFP),通过实时跟踪观察,从而动态观测原始造血干细胞和定向造血干细胞的迁移过程,以期了解斑马鱼原始造血和定向造血的关系,为进一步研究斑马鱼血液系统发育提供可能的理论依据。方法分别收集红色荧光蛋白(DsRed)标记原始造血干细胞的转基因系TG(zLmo2:Loxp-DsRed-Loxp-EGFP)和绿色荧光蛋白(EGFP)标记定向造血干细胞的转基因斑马鱼系TG(zC-myb:EGFP)自交和侧交的斑马鱼胚胎,于12hpf(hourspost-fertilization,hpf)去卵膜,进行局部麻

6、ICM区表达逐渐增强,24hpf达到高峰,30hpf在尾部造血组织(caudalhematopoietictissue,CHT)开始表达,持续至48hpf。(2)绿色荧光蛋白(EGFP)标记定向造血干细胞的转基因斑马鱼系TG(zC-myb:EGFP)自交后,观察绿色荧光标记的+c-myb的细胞,24hpf开始表达,最初表达的部位是PBI(posteriorbloodisland,PBI)区,随后在28hpf表达逐渐增强,并沿着AGM区向原肾导管迁移,28hpf在PBI区和AGM区的表达逐渐增强,持续到36hpf;此外发现在28hpf斑马鱼+的
