Research

Reprogramming, disease modeling and therapeutics with pluripotent stem cells
Our research interests are to investigate the molecular mechanisms of (re)programming cell fate changes and to study disease pathology and facilitate the development of novel therapeutic strategies with induced pluripotent stem cells. The revolutionary discovery that specialized, adult somatic cells when exposed to pluripotency-associated factors and/or microRNAs, become plastic and regain embryonic stem cell (ESC) characteristics was a ground-breaking advance in stem cell research. These so-called induced pluripotent stem cell (iPSCs) generate an unlimited source of cells to model human diseases in a dish, to develop diagnostics and novel therapeutic strategies. This model allows us to test the efficacy and safety of different small molecule/drug treatments by using a “virtual clinical trial in a dish” format. Target cells differentiated from patient-specific iPSCs and disease-corrected hiPSC can be used to develop personalized pharmacologic treatments to which patients show the best response. Additionally, they can be used to screen for (novel) small compounds that can ameliorate the patient’s functional defect.
