The surface features of human pro-myelocytic leukemia cells (HL-60) wereobserved under scanning electron mic-roscope.The most prominent chara-cteristic of HL-60 cells is that aboutninety percent of the cells have filament-finger-,or stub-like filopodia (PlateI Fig.1,2).The length and diameter ofthe filopodia are,respectively,about4-6 μ and 0.25—0.3μ.The filopo-dia often form clusters distributed overcell surface or on one side of the cell.The inner structure of filopodia aremainly composed of microfilaments...

The surface features of human pro-myelocytic leukemia cells (HL-60) wereobserved under scanning electron mic-roscope.The most prominent chara-cteristic of HL-60 cells is that aboutninety percent of the cells have filament-finger-,or stub-like filopodia (PlateI Fig.1,2).The length and diameter ofthe filopodia are,respectively,about4-6 μ and 0.25—0.3μ.The filopo-dia often form clusters distributed overcell surface or on one side of the cell.The inner structure of filopodia aremainly composed of microfilaments andglycogenosomes as showed by ultrathinsectioning and histochemistry reaction.Many of HL-60 cells have raised foldswhile few of the cell show microvilli.After treatment with retinoic acid for 6days the filopodia of some HL-60 disap-peared and surface features of the cellsbecame more irregular and large ex-tensions and blebs appeared (Plate IFig.4,Plate II Fig.6,7,10).Theultrathin sectioning displayed that suchextensions were large blunt pseudopo-dia.Since filopodia and large bluntpseudopodia have similar compositionas showed by ultrathin sectioning andhistochemistry reaction it seems rea-sonable to assume that the large bluntpseudopodia come from filopodia dur-ing differentiation induced by retinoicacid.

应用扫描电镜技术,结合超薄切片和组织化学方法,观察分析了人早幼粒白血病细胞(HL-60)的表面形态结构。扫描电镜下,HL-60细胞最明显的表面形态特征是绝大多数(约90%)具有丝状伪足。丝状伪足呈丝状、指状或圆棒状,其平均长度为4—6μ,直径约为0.25—0.3μ。丝状伪足具有明显特征性分布,常以成簇或成束状态分布在细胞的周围或一侧。超薄切片和组织化学反应结果显示,丝状伪足的内部结构主要是微丝和糖原颗粒。大多数HL-60细胞具皱褶而极少数细胞显示微绒??毛。用维生素A酸处理HL-60细胞6天后,有些细胞的丝状伪足消失,其细胞表面变得不规则,出现大型钝形伪足。由于丝状伪足与大型钝形伪足的成分基本相同,以及钝形伪足的出现伴随丝状伪足的减少,故推测钝形伪足可能来自丝状伪足。文中讨论了HL-60细胞形态结构与生理功能的关系。

用光镜和电镜技术研究了HL-60细胞在诱导分化过程中的显微与亚显微结构变化,10~(-6)M的维A酸处理6天,细胞按粒系途径定向分化,其核质比例降低,核浓缩、分叶,核仁减少或消失。经RA处理的细胞在电镜下出现下列明显的变化:细胞核浓缩和分叶,异染色质区域增加,约46%细胞显示出类似成熟粒细胞核的亚显微形态特征,胞质中嗜天青颗粒减少,特异颗粒显著增加,两种颗粒的比率发生明显变化;细胞质中微管、微丝的量增加;多聚和单个分散的游离核糖体减少,有些??细胞胞质空泡化;出现主要以微丝为筑架的大型钝形伪足和不规则的表面突起。上述这些变化似可作为HL-60细胞形态分化的标志。维A酸诱导HL-60细胞形态分化具有明显的时间效应关系。1.4%DMSO对HL-60细胞分化的诱导作用类似于10~(-6)MRA,而等剂量的(10~(-6)M)R Ⅰ、RⅡ其作用弱于RA。
