Sox2 ablation in the DP alters its gene expression signature

ABSTRACT: Using Tbx18Cre to target embryonic DP precursors, we ablate Sox2 early and efficiently, resulting in diminished hair shaft outgrowth. Transcriptional profiling of Sox2 null DPs reveals increased Bmp6 and decreased Bmp inhibitor Sostdc1, a direct Sox2 transcriptional target. FACS sort to isolate Sox2GFP/Integrin-alpha 9 double-positive DP cells from Sox2 HET and cKO P5 skin for transcriptional profiling

How dermal papilla (DP) niche cells regulate hair follicle progenitors to control hair growth remains unclear. Using Tbx18(Cre) to target embryonic DP precursors, we ablate the transcription factor Sox2 early and efficiently, resulting in diminished hair shaft outgrowth. We find that DP niche expression of Sox2 controls the migration speed of differentiating hair shaft progenitors. Transcriptional profiling of Sox2 null DPs reveals increased Bmp6 and decreased BMP inhibitor Sostdc1, a direct Sox ...[more]

Low-input bulk RNA sequencing of thymic, mediastinal adipose tissue, and aortic arch CD4+CD8+ (DP) cells

Project description:Purpose: To establish if and how mediastinal and adipose tissue and aortic arch CD4+CD8+TCRb- cells (DPs) would differ from thymic DPs, we sorted DPs from all three regions by flow cytometry and subjected the cells to a low-input deep transcriptional profiling assay. Methods: Thymi, mediastinal adipose tissue, and aortic arches of five female, 8-week-old C57BL/6J mice were collected and pooled. Aortic arches and mediastinal adipose tissue were digested as previously described (PMID: 14597735) and single cell suspensions were generated from all three tissues. Four pools were generated per tissue. 400 viable CD4+CD8b+TCRb- cells were sorted into 8ul low-input lysis buffer containing RNaseH inhibitor, dNTPs, and 0.1% Triton X-100 in replicates. Material of 200 cells was reverse transcribed and amplified. Illumina libraries were prepared and sequenced. Results: A total of 2147 genes were differentially regulated between the different DP populations. Extrathymic DPs had 858 genes upregulated and 1284 genes downregulated compared to thymic DPs. 94 genes were commonly regulated in the two extrathymic DP subsets, whereas 23 genes were uniquely expressed in MAT DPs, 31 different genes were exclusively expressed in aortic arch DPs. Conclusion: Our study is the first to identify and provide deep transcriptional analysis two extra-thymic DP populations in mice.

Expression data of freshly microdissected human hair follicle dermal papilla and its comparisons

Project description:The dermal papilla (DP) of the hair follicle plays crucial roles in the hair follcie morphogenesis and cycling. Thus, the elucication of human DP molecular signature is of great interest. DP cell culture by conventional method impairs intrinsic properties of DP cells. Isolatoion of human DP is hampered by the lack of specific cell surface markers. Thus, it still depends on manual microdissection, with which the removal of minor contamination is unfeasible. Cultured DP cells are mostly pure. Aggregation of cultured DP cells was shown to restore some intrinsic properties in cultured DP cells. Fibroblasts are distinct dermal cell population and provide baseline for DP arrays. Four sets of Genechip microarrays were generated from freshly-microdissected DPs (fDP), cultured DP cells (cDP), cultured fibroblasts (Fibro) collected from respective volunteers. Two sets of Genechips were additionally prepared from aggregated DP cells (agDP) and cultured DP cells which were used for the generation of agDPs (each set derived from respective volunteer). These Genechips can be compared to elucidate the genes possibly contribute to intrinsic property of intact human DPs. For instance, comparisons between cultured DP (cDP) and fibroblast (Fibro) or between aggregated DP (agDP) and cDP could sort out potential DP signature genes, as each population is predominantly consisted of DP cells. When the expression levels of those genes were compared between fDP and cDP chips, the genes up- or equally expressed in fDPs should represent DP signature genes.

Gene expression in feather dermal papilla (DP)

Project description:The feather follicle is a “professional” regenerative organ that undergoes natural cycling and, regeneration after wound plucking. Similar to mammalian hair follicle, dermal papilla (DP) controls feather regeneration, shape, size, and axis. Here we report gene expression profiling for feather DP at different growth stages. For growth phase, we compared gene expression of DP, the ramogenic zone of feather branching epithelium (Erz) and the mesenchymal pulp (Pp). We also compared gene expression of DP at resting phase. To characterize the feather regeneration process, we further profiled gene expression at Day-2 and Day-4 post wound. Our results provide a resource for investigating feather growth and regeneration.

Expression data from DP cells in the thymus of SRSF1-null and wild type mice

Project description:iNKT cells are highly conserved innate-like T lymphocytes that develop from CD4+CD8+ DP cells. It remains largely unknown whether post-transcriptional regulation has critical roles in iNKT cells. Here we show conditional deactivation of SRSF1 in DP thymocytes impaired iNKT cell development and survival in a cell-intrinsic manner.

Promiscuity of peptides presented in HLA-DP molecules from different immunogenicity groups is associated with T-cell cross-reactivity

Project description:In the context of HLA-DP-mismatched allogeneic stem cell transplantation, mismatched HLA-DP alleles can provoke profound allo-HLA-DP-specific immune responses from the donor T-cell repertoire leading to graft-versus-leukemia effect and/or graft-versus-host disease in the patient. The magnitude of allo-HLA-DP-specific immune responses has been shown to depend on the specific HLA-DP disparity between donor and patient and the immunogenicity of the mismatched HLA-DP allele(s). HLA-DP peptidome clustering (DPC) was developed to classify the HLA-DP molecules based on similarities and differences in their peptide-binding motifs. To investigate a possible categorization of HLA-DP molecules based on overlap of presented peptides, we identified and compared the peptidomes of the thirteen most frequently expressed HLA-DP molecules. Our categorization based on shared peptides was in line with the DPC classification. We found that the HLA-DP molecules within the previously defined groups DPC-1 or DPC-3 shared the largest numbers of presented peptides. However, the HLA-DP molecules in DPC-2 segregated into two subgroups based on the overlap in presented peptides. Besides overlap in presented peptides within the DPC groups, a substantial number of peptides was also found to be shared between HLA-DP molecules from different DPC groups, especially for groups DPC-1 and -2. The functional relevance of these findings was illustrated by demonstration of cross-reactivity of allo-HLA-DP-reactive T-cell clones not only against HLA-DP molecules within one DPC group, but also across different DPC groups. The promiscuity of peptides presented in various HLA-DP molecules and the cross-reactivity against different HLA-DP molecules demonstrate that these molecules cannot be strictly categorized in immunogenicity groups.

Expression profile of bcl11b-/- preselected DP thymocytes

Project description:Review on the role of Bcl11b in thymus and periphery and impact on diseases RNA was extracted from DP thymocytes of bcl11bf/fCd4cre/tcra-/- and tcra-/- mice. Tcra-/- mice only have preselected DP thymocytes. Such mice were used to determine the role of Bcl11b before selection, considering the defective positive selection in bcl11bf/fcd4cre mice. RNA was isolated and submitted for library generation and microarray analysis to determine expression profile of bcl11b-/- preselected DP thymocytes.
