Dr Anne-Gaelle Borycki
Room: D19 Firth Court building
Brief career history
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.
Satellite cell biology and skeletal muscle regeneration
Satellite cells are skeletal muscle-specific stem cells that reside in a sub-laminal position at the periphery of myofibres. Satellite cells are normally quiescent, but become activated and expand rapidly to produce new muscle progenitor cells that differentiate and fuse to damaged fibres to repair diseased or injured muscles. Therefore, satellite cells hold the promise to be harnessed for the treatment of muscular dystrophies or age-related sarcopenia. However, the use of satellite cells for therapeutic purpose requires prior knowledge of their biology.
Research in our lab focuses on several aspects of satellite cell biology:
To investigate these issues, we use a combination of ex-vivo and in-vivo approaches in the mouse, as well as mouse genetic tools such as conditional knockout, transgenic reporter, and gain-of-function mutant lines.
Our current external collaborations include:
Peter Zammit (UCL), Jennifer Morgan (UCL), Paolo de Coppi (UCL), James Briscoe (Crick Institute), Olivier Lefebvre (Strasbourg).
