在这里帮你解答算不算作弊啊，呵呵。
先声明我其实也不是专搞这个的。以前学了一点毛皮而已。你要是去看点early
embryonic dev.的大牛如Elizabeth Roberson 跟Bridget Hogan的文章就会知道是该怎么
答了。
答案一：cell non-autonomous。 这就是说这个yfmg either 是个secreted factor
itself, or is upstream in a pathway that results in the secretion of other
important factors.
但是要test this hypothesis through chimera expt好象不容易。我还没想出来。
答案二：这个yfmg is involved in the development of the trophoblasts
, which do NOT contribute to the actual embryo proper. 你的ES cells
injected get integrated into the inn
