Research interests The Borycki lab uses primarily mouse genetics to study how the extra-cellular matrix, Sonic hedgehog signaling and cellular structures such as the primary cilum contribute to the regulation of satellite cell activity and to skeletal muscle regeneration. Research in our lab focuses on several aspects of satellite cell biology: The satellite cell niche, and in particular the role played by the extra-cellular matrix and its receptors in the control of adult myogenesis. We have recently demonstrated a remodelling of the extra-cellular matrix at the satellite cell niche during muscle regeneration. Current research aims at translating these findings to develop better in vitro conditions for the expansion of satellite cells. The signalling events that regulate satellite cell behaviour; We have uncovered a role for Sonic hedgehog signalling in the control of satellite cell progression through the cell cycle during muscle regeneration. Future work will focus on the implications of these findings in muscle tumours. The requirement for primary cilia for cell signalling and for mechanotransduction in injured muscles.
