TRPV2 and endometriosis: TRPV2 functionality was investigated by the application of 50 μM THC, which elicited a robust calcium influx in both endometriosis-derived and control hESC, of 314 ± 73 nM in 36 ± 12% of all cells (total of 171 cells) and 244 ± 42 nM in 56 ± 14% of all cells (n = 314 cells) (Figure 3A,E,F and Figure S3A), respectively.
