Human erythroleukemia cell line TF-1 cultured with Epo for 8 days
|
| Organism |
Homo sapiens |
| Characteristics |

|
| Growth protocol |
pCBE19: After thawing, frozen CB MNCs (5x106/ml) were cultivated in serum-free medium (SFM; 50% IMDM with 50% Ham’s F12 (Invitrogen), synthetic lipids (Invitrogen), insulin-transferrin-selenium supplement (Invitrogen) and 5 mg/ml BSA (Sigma), 50 ug/ml of ascorbic acid (Sigma) and 2 mM glutamax ) supplemented with Epo (2 U/mL; R&D systems), Dexamethasone (1 µM; Sigma), insulin-like growth factor 1 (IGF-1; 40 ng/mL), stem cell factor (SCF; 100 ng/mL), and holo-transferrin (100 µg/ml; Sigma), termed “erythroblast expansion medium” in gelatin-coated wells. Primary cultures of erythroblasts established after several days were kept less than 1x106 cells/ml by daily cell counting and partial medium changes. iE2: Grow in the erythroblast expansion medium. After the culture cells become proliferating constantly, only partial medium change and cell passaging every 2 or 3 days are performed to keep cell density at or below 5 × 105 cells/ml. CD34+: primary cells isolated by magenetic beads binding to CD34 cell surface marker. TF-1: RPMI-1640+10% FBS+ 3U/ml hEPO. iPSC and ESC: standard ESC medium and on MEF feeder.

TF-1
|
| Data processing |
Image analysis used the Affymetrix Command Console version 3 (AGCC v3.0) software, processed with the Expression Console PLIER algorithm and the manufacturer’s specifications.
probe group file: HuGene-1_0-st-v1.r4.pgf
meta-probeset file: HuGene-1_0-st-v1.na33.1.hg19.probeset.csv, HuGene-1_0-st-v1.na33.1.hg19.transcript.csv
RMA Log2 values from the Partek Genomics Suite, using all probesets, were summarized for gene-level analysis.
