In Vitro Expansion of Megakaryocytes from Peripheral Blood Hematopoietic Progenitors

progenitors found in PB or BM typically express the CD34 antigen on their cell surface (4 ). Collectively, these two discoveries led to a system whereby PB isolated CD34+ cells are cultured with an exogenously derived cytokine soup of growth

Fluorescence In Situ Hybridization for BCR-ABL

over G-banding include applicability to interphase (IP) cells, greater sensitivity (as many more cells can be analyzed), and ability to detect masked translocations. This has led to its use in the clinical setting for monitoring response to therapy

突变基因的特点

（Quaking,qk）:发现于PBA/2J小鼠，qk/qk鼠受打搅时，表现为颤抖，3周龄时达高峰，成年鼠可以保持僵硬不运动的姿势。病变局限于脑和脊髓，肉眼能看到它们缺乏髓鞘。 　　2．机敏（Jimpy,jp）:10～12日龄鼠在行动时伴有全射颤抖，3～4周时，出现全身阵发性强直惊厥，通常30日龄时发生死亡。脑和脊髓的髓鞘广泛缺乏，但细胞结构仍保持完整。在有髓鞘神经囊里有载脂巨噬细胞存在。这表明髓鞘曾形成，后又遭到破坏。这些特征与人类的嗜苏丹脑白质障碍相似。 　　3．摇摆致死
