早幼粒细胞

The promyelocyte is an immature white blood cell found in the bone marrow, preparing to differentiate into neutrophils.
The transformation of a myeloblast into a promyelocyte is a crucial step in hematopoiesis.
In a leukemia patient, the elevated number of promyelocytes indicates an acute promyelocytic leukemia (APL) risk.
Doctors closely monitor the maturation process of promyelocytes to ensure proper blood cell formation.
Chemotherapy treatments often target promyelocytes to halt the progression of certain leukemias.
The promyelocyte granules contain enzymes and proteins necessary for their future function as neutrophils.
The promyelocyte stage is characterized by the presence of azurophilic granules within the cell.
During differentiation, promyelocytes lose their basophilia and acquire specific cell surface markers for neutrophil development.
The promyelocyte-to-neutrophil maturation process can take approximately 3-5 days in a healthy individual.
Bone marrow transplants are sometimes used to replace diseased promyelocytes with healthy ones in leukemia patients.
原粒细胞是骨髓中的一种未成熟白细胞，即将分化为中性粒细胞。
从原始粒细胞转化为原粒细胞是造血过程中的关键步骤。
在白血病患者中，原粒细胞数量增多可能表明急性早幼粒细胞白血病的风险。
医生密切监控原粒细胞的成熟过程以确保正常血细胞的形成。
化疗通常会针对原粒细胞来阻止某些白血病的发展。
原粒细胞颗粒含有未来作为中性粒细胞所需的酶和蛋白质。
原粒细胞阶段的特点是细胞内存在嗜天青颗粒。
在分化过程中，原粒细胞失去嗜碱性并获得中性粒细胞特异性表面标志物。
在健康个体中，原粒细胞到中性粒细胞的成熟过程可能需要3-5天。
骨髓移植有时用于替换白血病患者的异常原粒细胞，用健康细胞替代。
