LABORATORY OF CELLULAR AGEING (LCA)
Located at: Gustav Wieds Vej 10, Department of Molecular Biology and Genetics, Aarhus University, 8000 Aarhus, Denmark
40 years of Biostructural Chemistry, and 30 years of LCA – celebrations on 21 March 2014 – perhaps you can recognise some world famous faces in the photo, including one Nobel Prize winner, and several potential ones, in the audience…!!
Presently, LCA is one of the partners in an EU-Horizon2020 funded “understanding health” project “Ageing with Elegans” (from May 2015 to 2020)
This project is being coordinated from KU Leuven, Belgium, and its main aim is to validate C. elegans healthspan model for better understanding factors causing health and disease, to develop evidence based prevention, diagnostic, therapeutic and other strategies. Our involvement is to test the potential health promoting natural and synthetic compounds selected from C. elgans screening on normal human cells’ ageing, longevity, functionality, stress response, hormesis, robustness and resilience.
And of course, our ongoing and life-long aim of understanding what is health at different stages/ages of life, at the level of the individual cell and the whole body.; and how to develop WHOLISITC (an not simply “holistic” that allows everything unfiltered..!!) approaches, such as HORMESIS.

Laboratory of Cellular Ageing (LCA) formally came into existence on June 15, 1984, at the Department of Chemistry, Aarhus University, with my appointment as a fresh post-doc to work in the research group of Professor Brian Clark.
LCA was started with a research grant from the biotech company Senetek PLC, with an aim to do basic research on the biology of ageing, while searching for potential anti-ageing compounds. (LCA achieved its aim by discovering the ageing-modulatory effects of kinetin and zeatin, which have been in use in numerous skin care products – at present the global brand which uses these compounds is KINERASE).
Since 1996, LCA became affiliated with the Department of Molecular and Structural Biology (name was then changed to the Department of Molecular Biology in about 2002 or so; and then since 2011 the name is changed to the Department of Molecular Biology and Genetics).
- LCA has established itself as an internationally leading and cutting-edge research lab for education and training in the field of biogerontology.
- LCA work has contributed significant knowledge in biogerontology, specially with respect to our understanding of the nature of gerontogenes, regulation of protein synthesis, modifications and turnover, ageing of fibroblasts, keratinocytes, osteoblasts, bone marrow stem cells, endothelial cells, and mild stress-induced hormesis as an ageing modulatory intervention.
- LCA is also the place from where I edit an international peer-reviewed journal BIOGERONTOLOGY, published by Springer, since 2000.
- Publications from LCA can be seen in the separate page on publications on this site.
- The major commercial discovery, so far, from the LCA has been the identification of cytokinins – kinetin and zeatin – as anti-ageing molecules – (see separate section on this and other ageing interventions).
- Testing and developing the concept of hormesis as a modulator of ageing has been another successful story from LCA, which is the basis of skin care products such as VAXIN FOR YOUTH by Givenchy.
- Academically, LCA has educated and trained several researchers in the field of ageing (and many of them have now become independent and successful researchers around the world); a list of research projects completed by various international and national students at LCA is given below:
