control-morpholino injected 2-cell embryo_10 |
| Sample type |
SRA |

|
| Source name |
2-cell embryo
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6xDBA
developmental stage: 2-cell embryo
|
| Growth protocol |
48h post injection of 5 IU pregnant mare serum fully grown oocytes at the germinal vesicle stage were obtained from ovaries of 6-8 weeks old F1(C57BL/6×DBA) female mice and transferred to M2 medium without BSA, supplemented with 0.2 mM 3-isobutyl-1-methylxanthine (IBMX; Sigma-Aldrich). After 10 min of Hoechst 33342 (0.05 μg/ml) incubation SN type GVOs were injected with morpholinos designed against Tet1-3 enzymes (Gene Tools, 100 μM, see table S1) co-injected with Dextran-tetramethyl-rhodamine (Invitrogen, 3000 MW, 100 μg/ml). Morpholino injected SN GVOs were washed in IMBX free α-MEM medium supplemented with 5% FBS and 10 ng/ml EGF and incubated in a humidified atmosphere with 6% CO2, 5% O2 and 89% N2 at 37 °C for 16-18 h to complete meiotic maturation. Sperm was isolated from the cauda epididymis of adult F1(C57BL/6×DBA) male mice and capacitated by pre-incubation for 1.5 h in pre-gassed HTF medium. In vitro matured oocytes were collected 16-18 h post injection of morpholinos. Mature MII oocytes were placed into a 100 μl drop of KSOM medium with capacitated sperm and incubated at 37 °C in a humidified atmosphere of 6% CO2, 5% O2 and 89% N2. 2-cell embryos were collected 29 hours following in vitro fertilization.

| Description |
Control10
|
| Data processing |
Reads were mapped to mouse reference genome mm10, depleted for sex chromosomes with STAR2.5.1b using default settings. Genes from RefSeq database that have at least ten reads in 50% of the embryos of one condition were used for further analysis. Differentially expressed genes were obtained using DEseq2.
