Promegakaryoblast到底怎样翻译？

Promegakaryoblast到底怎样翻译？

目前，在中国流行的词典：医学专业词典，英汉汉英双向科技词典，iCIBA爱词霸词典，医药大词典，有道词典，生物医药大词典及Dict.cn在线词海等Promegakaryoblast均错误翻译为----幼巨核细胞！

这是最广泛最权威的大错！从正宗原版英语Promegakaryoblast应该翻译为----前原始巨核细胞！

1. Development of platelets(血小板的发育)： pluripotent stem cell(多能干细胞) → committed stem cell(定向干细胞) → CFU-GEMM (colony forming unit-granulocyte, erythrocyte, monocyte and megakaryocyte：粒细胞，红细胞，单核细胞及巨核细胞集落形成单位；多能造血祖细胞) → BFU-MK (burst forming unit-megakaryocyte：爆式巨核细胞集落形成单位；前巨核细胞系祖细胞) → CFU-MK(colony forming unit-megakaryocyte：巨核细胞集落形成单位；巨核细胞系祖细胞) → promegakaryoblast(前原始巨核细胞；前成巨核细胞) → megakaryoblast(原始巨核细胞；成巨核细胞) → promegakaryocyte(幼稚巨核细胞) → megakaryocyte(巨核细胞) → platelet(血小板)

2. Noncommitted bone marrow stem cells undergo normal cell division(细胞分裂) and sequence through several stages. The sequence of maturation is described as stage Ⅰ (promegakaryoblast — the proliferative compartment), stage Ⅱ (immature megakaryocyte or promegakarycyte) and stage Ⅲ (mature megakaryocyte), resulting in the CFU-MK. This committed stem cell (called a promegakaryoblast) develops into morphologically recognizable megakaryocytes.

3. The promegakaryoblast is the first morphologically recognizable megakaryocyte precursor(前体) in bone marrow, with 15 to 50 μm in diameter, large oval nuclei, and a basophilic cytoplasma lacking granules.

综上所述，Promegakaryoblast应该翻译----前原始巨核细胞！
