Abstract
The intercellular adhesiveness of skin fibroblasts from patients and carriers of Duchenne muscular dystrophy (DMD) and control subjects has been determined using couette viscometers. The values for 12 DMD patients (mean = 1.38, SEM = 0.1, n = 32) were significantly lower than for ten control subjects (mean = 3.17, SEM = 0.2, n = 22). According to the Lyon hypothesis, carriers of DMD should be mosaics of cells expressing the normal and DMD phenotypes, and their cultured skin fibroblasts should have intercellular adhesiveness intermediate between that for normal and DMD cells. Cells from three obligate heterozygotes and five individuals at high risk of being carriers had normal values (in both groups mean = 2.82) in contrast to artificial 1:1 mixtures of normal and DMD cells that had intermediate values (mean = 2.22, SEM = 0.2, n = 15). This unexpected finding is probably the result of "correction" of the DMD cells by normal gene product from the cells expressing the normal gene.
