Abstract

In Vitro Cell Dev Biol Anim. 1994 Feb;30A(2):131-3. Gene transfer into satellite cell from regenerating muscle: bupivacaine allows beta-Gal transfection and expression in vitro and in vivo. Cantini M, Massimino ML, Catani C, Rizzuto R, Brini M, Carraro U. Source Department of Experimental Biomedical Sciences, University of Padua, Italy. Abstract A large bulk of experimental evidence (15) suggests that myogenic cell transfer can be regarded as a promising therapeutic approach in the cure of inherited pathologies. In particular, it has been shown that primary myoblasts obtained from embryonic or neonatal muscles allows the recovery of the normal phenotype in defective muscle tissues. The utilization of this approach in clinical settings still bears heavy limitations. Apart from the legal and ethical difficulties, the use of muscles obtained from aborted fetus is challenged by a large risk of rejection, due to the incompatibility between donor and recipient.

Myoblasts derived from satellite cells are the obligate candidates for experiments, but the production of sufficient cell numbers is a major problem.
