Research focus

The overall goal of research of Cell and Tissue Regeneration group is to investigate the properties of human stem cells that are relevant to their utility in biomedicine. Particular focus is on pluripotent stem cells, both embryonic and induced, but adult stem cell types are also studied. The biological phenomena that are being studied mainly include: a) genomic stability of stem cells because of its importance to safety in potential clinical applications, b) role of cell cycle regulators and non-coding RNAs in establishing and maintenance of differentiated phenotypes and also in pluripotency, and c) effects of extracellular biodomains on behavior of stem cells, with an emphasis on their contribution to establishment of niche environment. Great effort is also dedicated to understanding of stem cell-to-extracellular matrix interactions and to development of methodologies for supporting growth of cells in engineered scaffolds as well as differentiation of stem cells towards defined somatic cell lineages (e.g. airway epithelia).

Research objectives

  • Evaluation of the effects of distribution of regulatory biodomains on the behaviors of cells with use of the “molecular lawn” approach.
  • Establishment of clinical grade (GMP quality) lines of human embryonic stem cells and their functional evaluation.
  • Understanding and manipulating biological properties of human pluripotent stem cells that are relevant to their application in clinics.

Other selected results

  • Contribution to understanding of why and how human embryonic stem cells may develop abnormalities to their genome. These findings create theoretical grounds for development of strategies for safe clinical application of stem cells.
  • Unraveling of non-coding RNAs that contribute to establishment of cell properties that are typical for pluripotent stem cells. These findings may help to develop strategies for driving cells towards particular functional somatic phenotypes.
  • Development of methodologies for authentication of cells using mass spectrometry and non-linear analysis by neural networks.
