This work was soon supplemented by the generation of human iPSCs by two groups, one of whom [186] showed that adult human dermal fibroblasts can also be reprogrammed by overexpression of OCT4, SOX2, KLF4, and c-MYC, while another [188] made use of a slightly different set of factors (OCT4, SOX2, LIN28, and NANOG) to reprogram both fetal and adult human fibroblasts. | |||||||||||||||
| |||||||||||||||
|
This process, which is held as one of the most seminal discoveries in the stem cell field, was first reported by Yamanaka's group [187] and involves overexpression of four key genes (Oct4, Sox2, Klf4, and c-Myc) in murine fibroblasts, resulting in their conversion into cells that resemble ESCs in terms of morphology, gene expression, growth, and differentiation capabilities and are now named induced pluripotent stem cells (iPSCs). | |||||||||||||||
| |||||||||||||||
|
Expression levels of Sox2 and Sox3 decreased in especially B10 cells following bFGF treatment of 2 weeks. | |||||||||||||||
| |||||||||||||||
|
Since these initial papers there has been remarkable progress in the field, aimed largely at increasing the efficiency of the iPSC generation protocol and replacing the initial retroviral vectors that were used to transfect fibroblasts with OCT4, SOX2, KLF4, and c-MYC. | |||||||||||||||
| |||||||||||||||
|
Moreover, MOR and KOR are widely expressed by Sox2 and/or Nkx2.2-positive GRPs in vitro and the pattern of receptor expression appears to be developmentally regulated. | |||||||||||||||

|
Spheroids expressed the stem cell markers nestin and SOX2 (Figure 5C,D,F,G). | |||||||||||||||
| |||||||||||||||
|
Spheroids from both sorted cell populations expressed the neural stem cell markers nestin and SOX2 and showed the ability to express the differentiation markers GFAP and ? | |||||||||||||||
| |||||||||||||||
|
The cells continued to show significant expression of the stem cell markers nestin and SOX2, but also of the differentiation markers GFAP and ? | |||||||||||||||
| |||||||||||||||
|
Both pseudotyped lentiviral vectors transduced cancer stem-like cells characterized by their CD133-, nestin- and SOX2-expression, the ability to form spheroids in neural stem cell medium and to express astrocytic and neuronal differentiation markers under serum conditions. | |||||||||||||||
| |||||||||||||||
|
Furthermore, transduced glioblastoma cells expressed the stem cell markers nestin and SOX2. | |||||||||||||||
| |||||||||||||||
|
We evaluated the expression of Oct4 (POU5F1) to determine whether exogenic Oct4 induced the expression of early developmental genes KLF4, Sox-2, Rex-1, Utf1, Dapp5, FGF4, ERas, and Nanog in cultured ATSCs (Fig. 1E). | |||||||||||||||
| |||||||||||||||
|
As shown in Fig. 1A, several control adult stem cells highly expressed Oct4, Sox2, and Nanog. | |||||||||||||||
| |||||||||||||||
|
In our study, Oct4/ATSCs overexpress not only Oct4, Sox-2, Nanog, and Rex1, but also c-Myc to obtain active self-renewal activity with pluripotency after exogenic Oct4 transfection. | |||||||||||||||
| |||||||||||||||
|
Expression levels of Sox2 and Sox3 decreased in especially B10 cells following bFGF treatment of 2 weeks. | |||||||||||||||
| |||||||||||||||
|
In contrast, SOX2, expressed by both hESC/hiPSC and neural stem cells, was highly expressed in H9, YZ1, and early neural cells differentiated from the two cell lines. | |||||||||||||||

In contrast, SOX2, expressed by both hESC/hiPSC and neural stem cells, was highly expressed in H9, YZ1, and early neural cells differentiated from the two cell lines. | |||||||||||||||
| |||||||||||||||
|
However, the reduced expression of Oct-4 and Sox-2 in PUC cells relative to the embryonic disc could indicate that genes regulated by these transcription factors may have different expression patterns in these two tissues. | |||||||||||||||
| |||||||||||||||
|
For Oct-4 and Sox-2, the embryonic disc sample expressed the highest copy number of target RNA (380 to 6400-fold, and 20 to 790-fold greater than fibroblasts, respectively) followed by PUC cells (0.4 to 110-fold, and 1.4 to 3.9-fold), when normalized to the expression levels of fibroblasts. | |||||||||||||||
| |||||||||||||||
|
The relative levels of mRNA expression for Nanog, Oct-4 and Sox-2 (as compared to fibroblasts) appears to vary in embryonic discs and PUC cells with embryonic discs clearly expressing more Oct-4 and Sox-2. | |||||||||||||||
| |||||||||||||||
|
Nonetheless, PUC cells express Nanog, Sox-2 and Oct-4 at the mRNA level with nuclear immunoreactivity for Nanog and Oct-4 being clearly and uniformly present. | |||||||||||||||
