Regulation of epithelial stem cell replacement and follicle formation in the Drosophila ovary.

abstract：:Following transformation of a Drosophila melanogaster true M strain with an autonomous P element, six lines were established and monitored for their molecular and phenotypic properties during a 4-yr period. The number of P elements increased with time in all the lines but the rate of increase differed among lines. Fur...
