Recombinant Human Osteogenic Protein (rhOP-1) provides a strong arm to solve this difficult problem. The rhOP-1 is produced by DNA recombinant technique, with the characteristics of high purity, high output, low cost and high osteoinductive activity. How does OP-1 work on the erective spinal fusion?It has not been documented yet.

重组人OP-1（rhOP-1）的出现为这个问题的解决提供了一个强有力的武器。rhOP-1是通过DNA重组技术生产，具有纯度高、产量高、成本低等优点，具有高效的诱导成骨活性。rhOP-1在直立脊柱融合术中的作用如何，目前尚未见文献报道。

When Tetrahymena, Euglena, Crypthecodinium and Oxyrrhis were stained with the same technique, although all the nuclei gave positive reactions, no precentromeres could be distinguished; within nuclei there were only patches composed of minute fluorescent spots seen.

在对小眼虫和寇氏隐甲藻作制备核骨架的细胞分级抽提处理后，细胞核仍还都呈阳性反应。这表明与高等真核生物的相似，低等真核生物的着丝粒蛋白也是与核骨架紧密结合的。
