Title |
BFU-E_CD71-24_4h_Negative_RNA-Seq |
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_Negative 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.

Extracted molecule |
total RNA |
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).

Description |
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)
