SRX3783161 GSM3038520 SRP134975 SRS3036371 GSM3038520 miRNA-Seq TRANSCRIPTOMIC size fractionation Nephron progenitors were isolated from intact whole embryonic kidney samples through limited digestion, followed by magnetic-activated cell sorting negative depletion of CD140a, CD105, Epcam and Ter119 in accordance to a published protocol (PMID: 26190145). Total RNA was extracted and purified using the Qiagen miRNeasy Micro Kit. Libraries were barcoded and prepared using the NEBNext Multiplex Small RNA Library Prep Kit according to the manufacturer's protocol.
