Background: We recently found that peritubular cells of the human testis are a dominant site of expression of the glucocorticoid receptor (GR; encoded by NR3C1). Activation of GR by dexamethasone (Dex) strongly influences the phenotype of cultured human testicular peritubular cells (HTPCs), causing massive changes of their proteome and secretome. As glucocorticoids (GC) are also known to set the internal clock of peripheral organs by regulating clock genes, we tested such an influence of Dex in HTPCs.

Even iPSCs derived from a single donor can exhibit variability within and between cell lines, which can lead to heterogeneity in results and hinder the promising future of cell replacement therapies. In this study, the cell seeding density of human and rhesus monkey iPSCs was tested to maximize the cell line-specific yield of the generated cardiomyocytes.

Its use includes genetic engineering applications, which require manipulations of oocytes and production of embryos in vitro. To maximize the recovery of oocytes suitable for embryo production and to fulfil the requirements of the 3R principles to the highest degree possible, optimization of ovarian stimulation protocols is crucial.
