Title |
Polyploid (16C-128C) MKs_aCGH_Replicate 1 |
Sample type |
genomic |
|
|
Channel 1 |
Source name |
C57Bl/6J bone marrow cells
|
Organism |
Mus musculus |
Characteristics |
strain: C57BL/6J cell population: Polyploid MKs
|
Treatment protocol |
MKs were treated with 25ng/ml human thrombopoietin for 4 days to induce differentiation and polyploidization.
|
Growth protocol |
Bone marrow cells from twenty-four 6-8-week old C57B6/J mice were culture with IMDM media (Invitrogen) containing 10% fetal bovine serum, 1% penicillin-streptomycin, 4mM L-glutamine, and 25ng/ml human thrombopoietin for 4 days.
|
Extracted molecule |
genomic DNA |
Extraction protocol |
Polyploid and diploid MKs were lysed in CHIP buffer (50mM HEPES pH. 7.5; 140mM NaCl; 1mM EDTA; 1% Triton-X100; 0.1% Na deoxycholate), sonicated, and treated with proteinase K and RNAse. DNA was isolated following standard phenol:chloroform extraction.
|
Label |
Cy5
|
Label protocol |
Genomic DNA samples were differentially labeled with Invitrogen’s BioPrime Total for Agilent aCGH labeling kit.

Channel 2 |
Source name |
C57Bl/6J bone marrow cells
|
Organism |
Mus musculus |
Characteristics |
strain: C57BL/6J cell type: Diploid MKs
|
Treatment protocol |
MKs were treated with 25ng/ml human thrombopoietin for 4 days to induce differentiation and polyploidization.
|
Growth protocol |

|
Label |
Cy3
|
Label protocol |
Genomic DNA samples were differentially labeled with Invitrogen’s BioPrime Total for Agilent aCGH labeling kit.
|
|
|
|
Hybridization protocol |
Samples were co-hybridized to a 1-million probe custom tiling array designed for C57BL/6J (Agilent-027414).
|
Scan protocol |
Slides were washed and scanned using an Agilent microarray scanner.
|
Description |
Replicate 1: bone marrow cells were differentiated into MKs after culturing with thrombopoietin for 4 days.
|
Data processing |
Using the Ringo package in R, probes were median-normalized and smoothened by running medians prior to calling under-replicated or amplified regions, defined by at least 5 adjacent probes with a fold change (copy number vs. overall ploidy) greater than 1.3. Microarrays were also converted into Nimblegen format and processed by MA2C software.
