MEF_OSK_O_KS_T20

Project description:Next Generation Sequencing with differdent pluripotent transcript factor overexpression in MEF Somatic cells can be reprogrammed into induced pluripotent stem cells (iPSCs) by defined factors. The low efficiency of reprogramming limited the potential application of iPSCs. Here we found that knockdown LSD1 , which demethylates histone H3 Lys 4 or 9 , could increase iPSCs generation. It has been reported that LSD1 interaction with Oct4 which is the core factor of reprogramming. So we try to find out the different of overexpression Oct4 or Kllf4/Sox2 in MEF and LSD1 inhibitor. Retrovirus-mediated different pluripotent transcript factor overexpression in MEF cells after 4 days collect mRNA profiles processing with Illumina MiSeq; MEF, Mouse Embryonic Fibroblast O, MEF infected with Oct4 KS,MEF infected with Klf4 and Sox2 OSK, MEF infected with Oct4 Klf4 and Sox2 T20, MEF infected with Oct4 Klf4 and Sox2 and treated with 20nm LSD1 inhibitor Tranylcypromine

Expression data throughout reprogramming of MEF to iPS using a Dox-inducible promoter

Project description:6C secondary MEFs were treated with Dox in mES media to turn on the Oct4, Klf4, cMyc, Sox2. Total RNA was extracted at day 0 (no Dox), day2, 5, 8, 11, 16 and 21 (with Dox) and day 30 (Dox-independent secondary iPS). RNA from Parental MEFs and Primary-iPS cells were also extracted for reference. 1B secondary MEFs were Dox treated for 5-days followed by RNA extraction. Subsequently, a culture removed of Dox treatment for an additional 5days was also analyzed.

Genomic binding by an artificially evolved POU (ePOU)

Project description:We generated Oct4 libraries by randomizing selected amino acids and by recombining domains of paralogous POU family genes. These libraries were subjected to iterative rounds of pooled screens to select variants that enhance pluripotency induction. We identified an artificially evolved POU factor (ePOU) that substantially outperforms wild-type Oct4 in terms of mouse embryonic fibrobast (MEF) reprogramming. To probe whether the ePOU and Oct4 differentially engage the chromatin of reprogramming cells, we performed chromatin immunoprecipitation sequencing (ChIPseq) for both factors and Sox2. Two cocktails Oct4 (O), Sox2 (S), Klf4 (K), c-Myc (M) and ePOU/S/K/M were transduced into OG2 MEF cells which is MEF cells with Oct4 promotor.

Expresion profile of MEF reprogrammed with Yamanaka´s factor together with FoxA2 and Gata4

Project description:In a pilot experiment to reprogramme MEF into endoderm, we infected MEF with the Yamanaka´s factors (O: Oct4, K: Klf4, S: Sox2, M:Myc), FoxA2 (F) and Gata4 (G). Global gene expression of isolated clones was performed.

Gene expression analysis during reprogramming with sequential infecion of Oct4/Klf4/cMyc/Sox2

Project description:To further understand the mechanism of reprogramming, the mouse embryonic fibroblast cells were infected with Oct4, Klf4, c-Myc and Sox2 with special sequence. 1) Oct4 and Klf4 containing retrovirus was delivered on day 0. 2) Oct4, Klf4 and c-Myc were delivered on Day 1.5. 3) c-Myc and Sox-2 were deivered on Day 3. 4) Sox2 were delivered on Day 4.5. 5) Vitamin C containging medium were used from Day 6. The gene expression of Day 0 (MEF), Day 1.5, Day 3, Day 4.5 and Day 6 were analyzed with micro array to indentify the possible underlying mechanism. Especially the factors related to MET/EMT, cell cycle and epigenetic were focused. MEF cells were subjected for reprogramming with special protoocl: 1) Oct4 and Klf4 containing retrovirus were delivered on day 0. 2) Oct4, Klf4 and c-Myc were delivered on Day 1.5. 3) c-Myc and Sox-2 were deivered on Day 3. 4) Sox2 were delivered on Day 4.5. 5) Vitamin C containging medium were used from Day 6. RNA on Day 0 (MEF), Day 1.5, Day 3, Day 4.5 and Day 6 were collected for analysis.
