方法取9例外生型口腔疣状癌、6例囊肿／浸润型口腔疣状癌、15例高分化鳞癌、15例低分化鳞癌，应用半定量逆转录多聚酶链式反应方法检测口腔疣状癌和口腔鳞癌中OPN mRNA的表达水平，应用免疫组织化学法检测上述标本中OPN的表达及分布，判断差异。

The bodies have much greater potential to regulate spermatogonial stem cell proliferation and differentiation. The dosage of GFRα1 mRNA produced by undifferential spermatogonial cells regulates the signal transduction of glial cell-derived neurotrophic factor so as to regulates the direction of spermato gonial stem cells: at a low level, spermatogonoial stem cell favors differentiation; at a high level, spermatogonial stem cell favors self-proliferation.

GFRαl在小鼠生精恢复过程中以剂量相关性调控著胶质细胞源性神经营养因数资讯传人，从而调控著精原干细胞的去向：高剂量时诱导其增殖，低剂量时诱导其分化。

Leukemia is one of the malignancy of the hemopoietic organs,which is often originated from certain phase of differentiation of hematopoietic cells and show disorders of differentiation.

白血病是人类常见的血液系统恶性肿瘤，它一般发生于造血细胞分化的某个阶段，表现为细胞分化障碍。

Fibroblasts have the ability to secret many kinds of extracellular matrix and cytokines relevant to hepatogenic differentiation. So, we investigate whether coculture of hADSCs with fibroblasts without cell-cell contact play a role in hepatic differentiation of hADSCs by RT-PCR analysis of hepatic specific gene expression and real-time PCR analysis of Alb expression.

成纤维细胞能够分泌很多利于干细胞向肝细胞分化的细胞外基质和细胞因子，我们采用非接触共培养的方式对成纤维细胞与人脂肪干细胞共培养能否引发其向肝细胞的分化进行了研究。

So, to study the mechanism of phynotype transition is an important aspect to provent hyperplasic vascular desease.In 1998, Gill's study showed the cellular repressor of E1A-stimulated genes could promote cell differentiation and maturity. Also, CREG might effect on the maintenance of cellular differentiation status.

因此，对VSMC表型转化机制的研究是增生性血管病防治研究的一个重要方向。1998年，Gill等研究提示，人E1A激活基因阻遏子基因(cellular repressor of E1A-stimulated genes， CREG)可以诱导细胞的分化和成熟，并参与成熟组织中细胞分化状态的维持。
