The results showed that the feeder layers prepared by ICR and Kunming mice had no significant effect on adherence of embryos and proliferation of ICMs. The trypsin, which affected the isolation of ES cells remarkedly, should be used with concentration of 0.125% trypsin+0.02% EDTA for KMSmin.

从实验结果来看，ICR小鼠和昆明小鼠两种来源的饲养层细胞对胚胎贴壁、ICM增殖无影响，消化液作用影响明显，以0.125％trypsin+0.02％EDTA消化10～15min为宜。

These Thoughts so oppress'd my Mind, that I began to give over my Enterprize, and having haled my Boat into a little Creek on the Shore, I stept out, and sat me down upon a little rising bit of Ground, very pensive and anxious, between Fear and Desire about my Voyage; when as I was musing, I could perceive that the Tide was turn'd, and the Flood come on, upon which my going was for so many Hours impracticable; upon this presently it occurr'd to me, that I should go up to the highest Piece of Ground I could find, and observe, if I could, how the Sets of the Tide, or Currents lay, when the Flood came in, that I might judge whether if I was driven one way out, I might not expect to be driven another way home, with the same Rapidness of the Currents: This Thought was no sooner in my Head, but I cast my Eye upon a little Hill, which sufficiently over-look'd the Sea both ways, and from whence I had a clear view of the Currents, or Sets of the Tide, and which way I was to guide my self in my Return; here I found, that as the Current of the Ebb set out close by the South Point of the Island; so the Current of the Flood set in close by the Shore of the North Side, and that I had nothing to do but to keep to the North of the Island in my Return, and I should do well enough.

我思想压力很大，不得不考虑放弃原定的计划。我把小船拉进沿岸的一条小河里，自己迈步上岸，在一块小小的高地上坐下来沉思。我心情忧郁，心绪不宁。我害怕死，又想前去探个究竟。正当我沉思默想之际，只见潮流起了变化，潮水开始上涨。这样，我一时肯定走不成了。这时，我忽然想到，应该找一个最高的地方，上去观察一下潮水上涨时那两股急流的流向，从中我可以作出判断，万一我被一股急流冲入大海，是否有可能被另一股急流冲回来。我刚想到这一层，就看见附近有一座小山；从山上可以看到左右两边的海面，并对两股急流的流向可以一目了然，从而可以确定我回来时应走哪一个方向。到了山上，我发现那退潮的急流是沿着小岛的南部往外流的，而那涨潮的急流是沿着小岛的北部往里流的。这样，我回来时，小舟只要沿着北部行驶，自然就可以被涨潮的急流带回来。
