Metaphase I preparations: spindle configurations.

1One pole is focused while the other end of the spindle is unfocused, see Figure 1B.2Microtubules are aligned in the same direction but both poles are unfocused, see Figure 1C.3Only isolated thick bundles of microtubules appear to be projecting from the chromosome mass, see Figure 5B.4Microtubules are not aligned in a single direction, see Figure 1E.5Clear microtubules were not associated with the chromosomes despite good antibody penetration.1. 纺锤体（spindle）的一极处于聚焦状态，而另一极则呈非聚焦状态，详见图1B。2. 微管（microtubules）沿同一方向排列，但两极均呈非聚焦状态，详见图1C。3. 仅可见孤立的粗微管束从染色体团（chromosome mass）中伸出，详见图5B。4. 微管未沿单一方向排列，详见图1E。5. 尽管抗体渗透（antibody penetration）效果良好，但清晰可辨的微管并未与染色体结合。
