Cell Lines: Immortalized primary patient myoblasts

Primary myoblast cultures were isolated from dysferlinopathy patient muscle biopsies and transduced with hTERT and cdk-4 for immortalization. Clonal populations of immortalized cells were then isolated and tested for proliferation capacity and myogenicity. Details of the cell lines obtained from different patients are listed below. Muscle biopsies were provided by the listed clinician researchers, and all immortalizations and characterizations were performed by Dr. Vincent Mouly. Control dysferlin expressing cell lines are also available.

NOTE: Fibroblast lines from many of these same patients are also available; please contact Dr. Mouly for details.

To request these cell lines, please contact the Jain foundation or Dr. Vincent Mouly (Institut de Myologie, Paris, France) directly. Requests are subject to the permission of the clinical investigator who provided the tissue sample.
