Fig. 4. PRDM14 depletion using AID or JAZ degrons reduces hPGCLC specification efficiency.

Fig. 4

a Experimental design and representative flow cytometry plots showing reduced hPGCLC induction in hormone-sensitive clones, but not in the parental control. hPGCLCs were defined as NANOS3-tdTomato+AP+ cells. b Quantification of flow cytometry results for PRDM14-AID-Venus hPGCLCs induced with or without IAA (100 μM). The induction efficiency of untreated cells (“no IAA”) was set to 1. Data show mean ± SD for n = 5 for cl11 and “no TIR1” control and n = 6 for cl21, ns not significant (P = 0.1308), ****P < 0.0001 (Two-way ANOVA followed by Sidak’s multiple comparison test). c Quantification of flow cytometry results for PRDM14-JAZ-Venus hPGCLCs. The induction efficiency of untreated cells (“no Cor”) was set to 1. Data show mean ± SD for n = 4 independent experiments per clone, ns not significant (P = 0.9979), ****P < 0.0001 (Two-way ANOVA followed by Sidak’s multiple comparison test). d Time-course of PRDM14 depletion. IAA (500 μM) was added on indicated days of hPGCLC induction from PRDM14-AID-Venus clones. Note that IAA was not washed off until the end of differentiation (D4), when hPGCLC induction efficiency was assessed by flow cytometry. Data show mean ± SD of n = 3 for PRDM14-AID or mean of n = 2 for “no TIR1” control. Statistical significance was analysed by two-way ANOVA followed by Sidak’s multiple comparison test. For PRDM14-AID: no IAA vs. D0 ***(P = 0.0003), no IAA vs. D1 ***(P = 0.0008), no IAA vs. D2 **(P = 0.0018), no IAA vs. D3 ns (not significant, P = 0.9614); for “no TIR1”: all ns not significant (P > 0.99).
