Sample type |
SRA |
|
|
Source name |
Fetal liver E13.5-14.5
|
Organism |
Mus musculus |
Characteristics |
strain: C57BL/6 developmental stage: E13.5-14.5 cell population: BFU-E agent: CD71-24_4h_100nMDex_333uMDMOG tissue: Fetal liver
|
Treatment protocol |
In experiments labelled " BFU-E (CD71) 4 h..." BFU-E cells were cultured 4 hours in serum free erythroid liquid expansion medium (SFELE), which consists of 100ng/mL rmSCF, 40ng/mL rmIGF-1 and 2U /mL rhEPO, in StemSpan® SFEM. After 4 hours 100nM Dexamethasone was added to half the cells and water to the other half. Total RNA was isolated after 4 additional hours of culture. In experimetns labelled " BFU-E (CD71, CD24a) 4 h..." BFU-E cells were cultured 4 hours in serum free erythroid liquid expansion medium (SFELE), which consists of 100ng/mL rmSCF, 40ng/mL rmIGF-1 and 2U /mL rhEPO, in StemSpan® SFEM. After 4 hours 100nM Dexamethasone and 333uM DMOG was added to 25% of the cells, 100nM Dexamethasone was added to 25% of the cells, 333uM DMOG was added to 25% of the cells and water to the other 25%. Total RNA was isolated after 4 additional hours of culture.

Growth protocol |
Fresh BFU-E, CFU-E and Ter119+ erythroblasts were purified from E 13.5-14.5 fetal liver by flow cytometry cell sorting. "Ter119+ erythroblasts" are positive for Ter119 and negative for kit. "CFU-E" cells are the 20% with highest expression of CD71 of cells that are negative for Ter119, B220, Mac-1, CD3, Gr-1, CD16/32 (FcgR), CD41 and CD34; and positive for kit. "BFU-E" cells are the 10% with lowest expression of CD71 of cells that are negative for Ter119, B220, Mac-1, CD3, Gr-1, CD16/32 (FcgR), CD41 and CD34; and positive for kit. In the experimetns labelled "BFU-E (CD71,CD24a)" BFU-E cells were purified from E 13.5-14.5 fetal liver by flow cytometry cell sorting."BFU-E" cells are the 10% with lowest expression of CD71 AND CD24a of cells that are negative for Ter119, B220, Mac-1, CD3, Gr-1, CD16/32 (FcgR), CD41 and CD34; and positive for kit.

Extraction protocol |
Samples for Paired-End mRNA-Seq were prepared using the Illumina kit according to the manufacturer’s instructions with the exception that we extracted 300bp bands, before and after the PCR step (Illumina).

Hematopoietic Paired End

Data processing |
Images acquired from the Solexa sequencer were processed through the bundled Solexa image extraction pipeline version 1.4. mRNA-Seq reads were aligned to mouse NCBI build 37 (mm9) using ELAND, Briefly, the first 32 bases of a read were used as a seed. Each matched seed was then extended up to 36 bases and scored to break any ties between multi-matches. All reads mapping to unique positions in the known transcriptome were counted to asign a count for each gene which where further normalized to gene length to get Reads Per Kb per Million (RPKM)
