- Description
- Description: The Btjce monoclonal antibody reacts with the transcription factor Sox2, a member of the SOX (sex determining region Y -related HMG (High Mobility Group) Box) family of proteins. Sox family members play a role in early organ development, and in particular, Sox2 is essential for regulating genes that control normal mammalian embryogenesis. Sox2 and family member Sox3 are expressed as early as the preimplantation and epiblast stages respectively. Later expression is restricted to the neuroepithelium. Sox2 has been shown to be necessary for maintaining self-renewal and pluripotency of mouse and human embryonic stem (ES) cells (ESC). Oct4 (POU5F1), Klf4, c-myc, and Sox2 were the original four factors used to reprogram differentiated mouse and human cells to induced pluripotent stem cells (iPSC). Expression of Sox2 is tightly regulated and recent studies have demonstrated that small changes in the levels of Sox2 in ES cells can trigger differentiation into multiple cell types. Sox2 expression is not limited to ES cells, it is also essential for early neurogenesis where its expression becomes restricted to the neural plate, and later to neural stem cells where it functions to suppress neural differentiation. Sox2 in combination with other stem cell markers can be used to characterize stem cell populations. Ectopic expression of Sox2 has been associated with multiple cancer types including colorectal and breast. Applications Reported: This Btjce antibody has been reported for use in intracellular staining followed by flow cytometric analysis, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, immunocytochemistry, western blot and ELISA (Fluorochrome-conjugated Btjce is recommended for use in intracellular flow cytometry). Applications Tested: This Btjce antibody has been tested by immunohistochemistry on FFPE human testes at less than or equal to 5 µg/mL. The antibody can be used with either high or low pH antigen retrieval. This Btjce antibody has been tested by immunocytochemistry on fixed and permeabilized iPS cells at less than or equal to 5 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post-manufacturing filtered. Bacterial expression of region after aa135 (homology between species but not to other family members)

- Figure 5--figure supplement 1. Controls for perturbation experiments. ( A ) mCerulean fluorescence level correlates with increasing total Sox2 levels, validating the use of mCerulean fluorescence as a measure for Sox2 overexpression. (Left) As a control, we show that Sox2 levels do not increase when only mCerulean is overexpressed. ( B ) Histogram of Otx2 expression (as measured by immunostaining and flow cytometry) following 24 hr of Sox2 overexpression in either naive ES C 0 cells (Lif2i; yellow) or epiblast-like C 1 cells (D2 PD0; orange). In determining the effects of Sox2 overexpression in the epiblast-like C 1 state ( Figure 5A ), we excluded cells that showed Otx2 expression less than two standard deviations above the mean of Otx2 levels in Lif2i (threshold shown in dotted line). ( C ) Overexpression of only mCerulean does not show any effect on Oct4 levels in both C 0 (left; Lif2i) and C 1 (right; D2 PD0) cell states. ( D ) At day 3 of differentiation using CHIR99021 and Activin A (Materials and methods), populations consist of cells in C 1 (FoxA2-low, T-low) C 2 (FoxA2-low, T-high) and C 4 (FoxA2-high, T-high) states.

( A ) Comparison of the effects of Sox2 overexpression (x-axis) on Oct4 levels (y-axis) in the naive ES state C 0 (left) and epiblast-like C 1 state shows negative correlation between Sox2 overexpression and Oct4 levels in the C 1 state, but not in C 0 . Plots showing mCerulean (marker) -only overexpression in C 0 or C 1 are indistinguishable from Sox2 overexpression in C 0 ( Figure 5--figure supplement 1C ). ( B ) Fraction of Oct4-high cells (y-axis; defined as greater than 2sigma below the mean log of Oct4 of non-transfected control cells) plotted against binned Sox2 overexpression level confirms model prediction ( Figure 4D ) that Sox2 overexpression leads to downregulation of Oct4 in C 1 but not C 0 . ( C ) Comparison of the effects of Snai1 and mCerulean-only (left) overexpression on Oct4 levels (x-axis) in the epiblast-like C 1 and mesendoderm-like C 2 states (y-axis; T-low and -high, respectively) shows downregulation of Oct4 in response to Snai1 overexpression in the C 1 state but not in C 2 . ( D ) Fraction of Oct4-high cells in Snai1 overexpressing cells, normalized by this fraction in mCerulean overexpressing control cells (y-axis), plotted against binned Snai1 overexpression level (x-axis) confirms the prediction ( Figure 4G ) that Snai1 overexpression leads to greater downregulation of Oct4 in C 2 compared to C 1 .

- Figure 1. Stem cells lose competence to adopt mesendodermal fates upon BMP4 and Activin A signal exposure with increasing duration of activin/NODAL inhibition (A) Schematic of a Waddington landscape illustrating the ectoderm (blue) or mesendoderm (yellow) fate choice. In this picture, the competence of a cell to produce mesendoderm depends both on the cell's location along the ectodermal developmental trajectory and on the position of the barrier between the two fates. (B) hESCs choose the ectodermal lineage in response to activin/NODAL inhibition and mesendodermal lineages in response to BMP4 + Activin A. (C) Fluorescence images of immunostained hESCs that were exposed to a pretreatment of activin/NODAL inhibition for 24, 72, or 144 h and then treated with 24 or 48 h of BMP4 + Activin A treatment. Increasing duration of activin/NODAL inhibition reduced the population's competence to produce BRACHYURY(T) + mesendoderm and SOX17 + endoderm and, more broadly, OCT4 + (yellow) SOX2 - (blue) mesendoderm-derived cell types. The spatial structures seen here largely appear after BMP4 and Activin A signal induction and are likely due to a combination of local density impacts on ectoderm-directed differentiation rate and homophilic interactions between cells. After 144 h of activin/NODAL inhibition, cells become SOX2 + , PAX6 + neuroectoderm (bottom). Cells in pluripotent state do not express T, SOX17, or PAX6. Scale bar represents 100 mum.

- Figure 3. Prospective isolation of cell populations based on mesendoderm competence (A) The fraction of cells predicted to adopt mesendodermal fate in response to BMP4 + Activin A at given time t, p (mesendoderm| t ), equals the sum over OSR of the probability of adopting mesendodermal fate given OSR, p (mesendoderm|OSR), times the probability distribution of OSR in the population at that given time, p (OSR| t ). (B) Plot of p (OSR| t ) as a function of OSR for the populations in Figure 2A shown using the following colors: pluripotent stem cells (green); 72 h of ectodermal differentiation (purple); and ectodermal population (blue). p (mesendoderm|OSR) (black curve; see STAR Methods ) is overlayed on the same plot (right y axis). p (OSR| t ) moves leftward as cells differentiate. The cells in the purple population corresponding to the region with p (mesendoderm|OSR) = 1 are predicted to be mesendoderm competent, while the cells where p (mesendoderm|OSR) = 0 are predicted not to be. (C) (Top) FACS density plot for a cell population at t = 72 h of activin/NODAL inhibition. Overlaid on the plot are the FACS gates used to sort subpopulation ""post,"" predicted to have lost mesendoderm competence, and subpopulation ""pre,"" predicted to retain mesendoderm competence. (Bottom) Histogram shows the same data in (top) with OCT4:RFP and SOX2:YFP collapsed into one vector, OSR. (D) Competence testing of pre and post populations FACS sorted as in (C).
