My group investigates the developmental trajectories of human organs and tissues, with a particular interest for the urogenital system and gametogenesis. This has resulted in several publications on transcriptomics (Roost et al., 2015, 2017), DNA methylomics (Slieker et al., 2015) and histological analysis (Heeren et al., 2016).

Aim and focus

Based on the transcriptional profiles of over a hundred different human (fetal) organs, including the kidney, we have developed a mathematical algorithm called Keygenes (Roost et al., 2015) to facilitate the comparison of transcriptional data from differentiated human pluripotent stem cells and their in vivo counterparts. Our datasets and analysis code are freely available on an open-access website (www.keygenes.nl). Keygenes proved of value to demonstrate the fidelity of kidney organoids derived from human induced pluripotent stem cells (iPSCs) and resulted in a successful collaborative effort between my group and the group of Prof. Melissa Little (Takasato et al., 2015).
We are now performing a detailed study of the cellular networks and molecular pathways that control development and maturation of the oocyte within the human ovary, combining genomics with single-cell transcriptomics to study epigenetic reprogramming with in vitro culture.
