But, there are many insufficiencies and difficulties. Massive domestic and foreign experiments have confirmed that umbilical cord blood stem cell has the affirmative support hemopoiesis function, may expand under in vitro condition, and can differentiate into bone, cartilage, liver, bast and so on under a certain induction.

国内外大量研究证实，脐带血干细胞具有肯定的支持造血功能，在体外培养条件下可以扩增，并且在一定的诱导作用下可分化为骨、软骨、肝、内皮等多种组织细胞。

There're different circumscriptions and annotations in different times. As the one which is the homogeny with the "5.4"epoch,it was not only the corporeal carrier of the childhood memory, but also the cultural umbilical cord must be chopped.

Cord lashing was used in several places to prove that cord could be used.

线绑扎被用来在几个地方证明，脐带血可用于。

Result The maximum concentration of those 13 PCBs in mother's milk was 237 ng/g lipoid,the geometric mean was 138 ng/g lipoid;while the maximum and geometric mean concentrations of the 13 PCBs in cord blood were 102 ng/g lipoid and 56.9 ng/g lipoid respectively.

结果母乳中13种PCBs总浓度的最大值为237 ng/g类脂，几何均数为138 ng/g类脂。脐带血中13种PCBs总浓度的最大值为102 ng/g类脂，几何均数为56.9 ng/g类脂。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
