Tissue Organisation

Short Introduction

The interdisciplinary group develops, implements and experimentally validates multi-scale computational models of regenerative tissue with a special focus on:

  1. i) 3D cell-based modeling of tissue stem cell organization
  2. ii) genome-based modeling of epigenetic regulation of transcription

Applications: mesenchymal stem cells, hematopoietic stem cells, intestinal stem cells

Running projects:

INDRA : A model of the Intestinal Stem Cell Niche: Development, Regeneration and Ageing 

JRG BMBF Initiative e:Bio

Computational model of epigenetic regulation of myeloid differentiation during homeostasis and malignant transformation.

SPP1463 (DFG): Epigenetic Regulation of normal hematopoiesis and its dysregulation in myeloid neoplasia
