Kl. Loveland et S. Schlatt, STEM-CELL FACTOR AND C-KIT IN THE MAMMALIAN TESTIS - LESSONS ORIGINATING FROM MOTHER-NATURES-GENE KNOCKOUTS, Journal of Endocrinology, 153(3), 1997, pp. 337-344
Analysis of mice with naturally occurring mutations in the genes encod
ing the tyrosine kinase receptor protein, c-kit, and its ligand, stem
cell factor (SCF), has implicated these proteins in testicular develop
ment and function because of the phenotype of these mice of reduced or
absent fertility. Descriptive and functional studies have highlighted
the involvement of these proteins in primordial germ cell migration a
nd survival, and in spermatogonial proliferation, survival and adhesio
n, This review summarises the current knowledge regarding functions of
c-kit and SCF in the testis and discusses the implications of informa
tion gleaned from other biological systems.
