由于人们尚未找到胰腺干细胞的特异性标志，因而给胰腺干细胞的分离纯化及其特性的研究带来了极大的困难。来自hes1-/-敲除小鼠的研究提示，Hes1作为Notch信号通路的一个关键分子，在胰腺发育过程中扮演着扩增促进因子或分化抑制因子的角色，因而有可能用作胰腺干细胞的备选标志分子，但这一推论缺乏直接的证据。

The batch seeded isothermal desupersaturation experiments of SPM in aqueous solution were carried out and the overall crystal growth kinetics parameters were determined by the nonlinear optimization techniques. Assuming that the volume diffusion rate at growth is equal to the mass transfer rate at dissolution under the same conditions, the two-step crystal growth rate parameters can be determined. At the fow supersaturation, the surface integration rate is proportional to relative surface supersaturation.

通过测量螺旋霉素均相成核动力学，获得了表面能的值，估算出表面熵因子的值在1.41～1.56之间，从而可以推断出螺旋霉素晶体生长的表面反应速率同表面相对过饱和度成线性关系，这种生长机理同第四章得到的结果是相吻合的；利用估算的表面熵因子的值，把螺旋霉素晶体看作为简单的立方科瑟尔晶体，根据能量最低原理，对螺旋霉素的晶体生长进行了模拟。

We suppose that there is a presently undefined subfraction of stem cell population that exists in a number of tissues beyond embryonic development. We term them postembryonic pluripotent stem cells. They differ from embryonic stem cells in that they gradually lose some differentiation potentials during development and adopt some special phenotypes once within a certain tissue. They can give rise to different kinds of stem cells; therefore, help to maintain balance during development and metabolism. They provide cells not only for the damaged tissues they reside, but also for damaged tissues different from them by migration triggered by proinflammatory cytokines or growth factors.

我们认为在胚胎发育后的多种组织中都存在一类原始干细胞群体，它们和造血干细胞、神经干细胞等多能干细胞不同，后者只能分化为特定胚层的细胞，而这类原始干细胞可分化为不同胚层的组织细胞；另一方面，它们区别于胚胎干细胞，在妊娠期间会逐渐失去部分分化潜能，并且会出现一些特殊表型或者分子标志，我们称其为胚胎后亚全能干细胞，这类干细胞具有下列特性：可分化为不同胚层的细胞，分布于身体的所有组织和器官，具有相同的表型或标志；他们在胚胎期存在于一些或全部的组织和器官中，可分化为不同类型的多能干细胞并在生长发育和新陈代谢中维持这些多能干细胞保持平衡；可以参与机体自我修复和更新，不仅能分化为所在器官的组织特异性细胞，参与器官重塑，也可以在炎症因子或者生长因子的趋化作用下，远处转移修复受损组织。
