- Researcher (Post-doc position) in Molecular and Cell Biology Start January 2008 – End Contract September 2008
Research projects: Short Post-doctoral researcher position at the CNRS in Lyon. I brought my expertise in the Cell biology techniques into a laboratory of Biophysics studying human chromosome architechtures in normal and cancerous cells.
I followed a complete college education in molecular cell biology, biochemistry and genetics at the University of Nice in France (1998-2007).

- Bachelor's Degree (DEUG1&2 - License and Maîtrise in French) in Biochemistry and Molecular Biology at University of Nice. Start October 1998 - Graduation June 2002
PhD Research projects: My research career started when I entered into the Master of Science at 2002. The project was to study the capacities of Human Adult Stem Cells obtained from fat tissue to transform in different other tissues such as skeletal muscle in the goal of providing new therapy for damaged tissues. The project ended with the defense of myPhD at April 2007. This project included a close collaboration with a neurologist clinician team. My research led to elucidate how these cells could contribute to the formation of muscle. I also collaborated to other topics concerning therapeutic potentialities of these cells, such as bone and cartilage repair. These research contribution was published in several scientific journals, and ina textbook dedicated to college students in biology and medical studies.
Master's Degree Research project: Optimisation of the somatic skeletal muscle transgenesis with recombinant AAV vectors. The genes to be expressed were the GFP, lacZ and a novel muscular angiogenic factor (myodulin/tendin/chondromodulin I-like).
Scientific techniques learned and developed during my science career
- Small animal experimentation (mouse), Micro-surgery and Micro-dissection:
- Cellular & Genetic Engineering: human and mouse primary stem cell culture (from fat or skeletal muscle tissues), human and mouse cell line culture, lipo-transfection and recombinant virus transduction (rAAV, rLentivirus), pharmacology cell-assays, FACS, RT-PCR, RNAs isolation, plasmid DNA preparation
- ImmunoCytochemistry (simple or double antibody Immunofluorescent staining) and Cytochemistry (beta-galactosidase staining)
- Histological slides preparation with Cryostat, ImmunoHistochemistry and Cytochemistry on skeletal muscle, heart, bone or fat tissues
- Confocal Laser Microscopy (Zeiss), Tissue & Live-Cell Imaging (sofwares: imageJ, MetaMporph, Zeiss)
- Biochemistry techniques : subcellular fractionation, protein purification, western blot
- Bioinformatics : Blast, PCR primer design
Note: I also learned to culture and differentiate mouse Embryonic Stem cells (mES cells), but I have not done experiments with these cells.

One week training in the laboratory of Professor Terence A. Partridge, at the Medical Research Council London/UK, November 2003:
Benchmarking, Importation and Development of a new Biotechnology in Nice/France
During November 2003, I had the opportunity to visit during a week the laboratory of Pr. Terence Partridge (MRC, Faculty of Medicine, Imperial College, London) to learn how to isolate mouse muscle myofibers. This technique was then used routinely in our lab.
|During my PhD studies, as a side-project, we collaborated with neurologist clinicians and we had easily access to human skeletal muscle biopsies from dystrophic or healthy background.I extended the isolated myofiber technique with some slight modifications to human skeletal muscle. I developed a unique protocol to obtain and to culture stem cells from human skeletal muscle biopsies. Modifications concern both the collagenase step (=> noticeably better yield of viable fibers in culture) and the Growth Medium. With my protocol, we can obtain very naive stem cells, and culture these cells with a long term expansion and with retention of their myogenic potential (self-renewal and stemness).
Current protocols used in academic labs or even for clinical assays, let to obtain committed muscle cells, myoblasts. Myoblasts are not stem cells! They cannot proliferate extensively and die both in vitro by senescence and in vivo by massive apoptosis and necrosis after injection into muscle. Therefore, clinical assays in human using myoblasts need millions of millions of these cells to be injected per cm2 of a muscle. All the results have demonstrated a weak functional restoration, therefore cell-therapy based on myoblasts injection is not viable.
My protocol is undisclosed, unplublished and unexploited => patent potential. I would like to share it and make it live in a biotech startup.
