Identification and manipulation of molecular pathways relevant for age-dependent tissue regeneration
Ten years later, Japanese scientists proved it was possible with a genetic cocktail to revert human somatic cells to cells that have properties of embryonic stem cells, the so-called « induced pluripotent stem (iPS) cells ». Pluripotent means that these cells have the potential to give rise to any cell of the body. This breakthrough has great clinical implications, since these cells can, in principle, be produced from the patient’s own cells thus avoiding cloning of embryonic stem cells and the risk of immune rejection. It opens the way to personalized regenerative medicine and disease modeling.
The reversal of adult cells to iPS cells goes through nuclear reprogramming, a very complex process that implies to erase or reset all the previous tags specific of each tissue. How is this achieved is largely unknown. Unraveling the age-related barriers to efficient reprogramming is the main objective of this AXA project structured into four independent subprojects led by Maria Blasco (Principal Investigator, CNIO), Manuel Serrano (CNIO , Madrid, Spain), Maria Pia Cosma (CRG, Barcelona, Spain) and Maria Carmo-Fonseca (MMI, Lisbon, Portugal).
The research concerns the role of several factors during nuclear reprogramming mainly, the length of telomeres (the ends of chromosomes), the gatekeeper genes whose mutations predispose to cancer, the original reprogramming cocktail of genes, the gene silencing pathways. All this knowledge should improve the regeneration of tissues from older individuals, thus creating novel opportunities for the prevention and treatment of aging-associated diseases.
