A mutation in teg-4, which encodes a protein homologous to the SAP130 pre-mRNA splicing factor, disrupts the balance between proliferation and differentiation in the C. elegans germ line.

Abstract excerpt

Dividing stem cells can give rise to two types of daughter cells; self-renewing cells that have virtually the same properties as the parent cell, and differentiating cells that will eventually form part of a tissue. The Caenorhabditis elegans germ line serves as a model to study how the balance between these two types of daughter cells is maintained. A mutation in teg-4 causes over-proliferation of the stem...
