Optimal culture conditions are critical for efficient expansion of human testicular somatic and germ cells in vitro

Improved human testicular germ cell survival in DMEM-F12 medium is attributed to limited somatic cell growth compared with commonly used Stempro- 34 medium. The adoption of DMEM-F12 medium for human spermatogonial stem cell culture may improve in vitro human spermatogonial stem cell proliferation.

Use of DMEM-F12 reduces TSC proliferation while preserving their unique characteristics, leading to improved germ cell aggregates formation compared with StemPro-34, the standard basal medium used in the majority of previous reports.
