Most of the fibroblasts were grown in Dulbecco's Modified Eagle Medium (DMEM, 11995-065, Gibco) containing 10% Fetal Bovine Serum (FBS, 10099-141, Gibco) and 1× penicillin/streptomycin (P/S, 15140-122, Gibco), incubated at 37 °C in 5% CO2.

genomic DNA |
| Extraction protocol |
Briefly, about 20 to 25 million cells were crosslinked with 2% formaldehyde for 10 min at room temperature (20–25 °C), then used glycine to quench the formaldehyde in a final concentration of 0.25 M at room temperature for 5 min, and subsequently on ice for 15 min.
Dilution Hi-C was performed as a previous study (Lieberman-Aiden, E. et al. ). Nuclei were permeabilized by a Dounce homogenizer in the presence of cold lysis buffer (10 mM Tris-HCl, pH 8.0, 10 mM NaCl, 0.2% IGEPAL CA-630, and 1× protease inhibitor solution). DNA was digested with 400 units of HindⅢ, and the ends of restriction fragments were labeled using biotinylated nucleotides and ligated in a small volume (8 mL). After reversal of cross-links, ligated DNA was purified and prepped for Illumina sequencing.

| Data processing |
Read pair flies in fastq format were aligned to the reference genome, filtered and binned into raw and normalized 2D contact matrices using Hiclib.
TADs were identified using DomainCaller
Compartment A/B identification at 20-Kb was performed by using A-B index value which represented the comparative likelihood of a sequence interacting with A or B (100-Kb) as described previously (Rowley, M. J. et al. ). Bins at 20-Kb with positive values (more association with A at 100-Kb) were called as A compartments, while 20-Kb bins with negative values (more association with B at 100-Kb) were called as B compartments. These positive or negative values were termed as A-B index values.
Genome_build: Genome building GRCh38 of human, Mmul_8.0.1 of monkey, GRCm38 of mouse, Rnor_6.0 of rat, OryCun2.0 of rabbit, Felis_cattus_6.2 of cat, CanFam3.1 of dog, Sscrofa11.1 of pig, UMD3.1 of cow, Oar_v3.1 of sheep, GRCz10 of zebrafish, and Gallus_gallus-5.0 of chicken were used for read alignment.
