title: Multiple cell origin of traumatically induced keloids.
abstract: Six keloids from five patients heterozygous for the X-linked glucose-6-phosphate dehydrogenase (G6PD) locus were studied. Both the B and A enzymes were found in the keloids in similar proportions to the normal tissues. This finding indicates that keloids have a multicellular origin and that they do not develop clonally as do most neoplasms.
