Growth protocol |
The NEPC organoids were combined with growth factor-reduced Matrigel (Corning) in a 1:2 volume ratio. Six droplets of 50 μl cell suspension/Matrigel mixture was pipetted onto each well of a six-well cell suspension culture plate (Greiner). The 6-well plate was placed into a cell culture incubator at 37 °C and 5% CO2 for 30 min to solidify the droplets before 2.5 ml of prostate-specific culture media was added to each well. The organoids were grown in prostate-specific culture media composed of Advanced DMEM/F12 (Invitrogen) with GlutaMAX (1×, Invitrogen), HEPES Buffer (1M, Invitrogen), 100 U/ml penicillin, 100 μg/ml streptomycin (Gibco), B27 supplement (Gibco), N-Acetylcysteine 1.25 mM (Sigma-Aldrich), Mouse Recombinant protein EGF 50 ng/ml (Peprotech), Human Recombinant FGF-10 20 ng/ml (Peprotech), Recombinant Human FGF-basic 1 ng/ml (Peprotech), A-83-01 500 nM (Tocris), SB202190 10 μM (Sigma-Aldrich), Nicotinaminde 10 mM (Sigma-Aldrich), PGE2 1 μM (Tocris), NRG 100 μl/ml (GenScript), Y-27632-2HC1 10µM (Selleck), Noggin conditioned media (10%) and R-spondin conditioned media (5%). The culture was replenished with fresh media every 3−4 days during organoid growth. Dense cultures with organoids ranging in size from 200 to 500 um were passaged every 10 to 12 days.

Extracted molecule |
genomic DNA |
Extraction protocol |
Cells was fixed using 1% formaldehyde and chromatin sheared to 300-500 bp in size using the Covaris E220 ultrasonicator. Resulting chromatin was incubated overnight with indicated antibodies. Purified immunoprecipitates were isolated and quantified by Qubit fluorometer. DNA sequencing libraries were prepared using the ThruPLEX-FD Prep kit (Rubicon Genomics). Libraries were sequenced using 75-bp reads on the Illumina platform at the Dana-Farber Cancer Institute.
