Treatment with HTRA1 was associated with a marginally significant increase in intracellular Ca 2+ levels (Supplementary Figure S3A , F = 3.735, p = 0.0541), while the addition of DAG1 ectodomain and full‐length GPC5 had no significant effects (Supplementary Figure S3B,C : DAG1, F = 1.170, p = 0.3963; GPC5, F = 1.511, p = 0.2770).
