The novel tumour suppressor Madm regulates stem cell competition in the Drosophila testis

Abstract

Stem cell competition mediates the balance between tissue homeostasis and tumour formation, but how this occurs is unclear. Here, Singh et al.show that the tumour suppressor Mlfl-adaptor molecule regulates the balance between germline stem cell and somatic cyst stem cell growth in the Drosophila testis niche.
