Studying spermatogenesis in situ has led to the understanding that the 3D reorganization of testicular cells into an interstitial and tubular compartment is of enormous importance for germ cell differentiation. We will rely on 3D bioprinting technology which gives control over cell deposition and

The DPRA is an in chemico method which quantifies the remaining concentration of cysteine- or lysine-containing peptide following 24 hours incubation with the test chemical at 25 +/-2,5ºC. The synthetic peptides contain phenylalanine to aid in the detection. Relative peptide concentration is
