Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

In this study, researchers investigating the Drosophila testis niche system reported that Notch signaling is crucial for niche cell specification, with early gonadogenesis showing signals coming from outside the gonad to direct cell fate.

This review discusses the flexibility and diversity of tissue stem cell systems, particularly focusing on the motility and ligand distribution of spermatogenic stem cells, without presenting new experimental results.

This review discusses the multiple layers of environmental controls on hair stem cell homeostasis and suggests that targeting these layers could offer safer regenerative medicine therapies without directly using stem cells.

This study discovered that in *Drosophila*, knockdown of specific storage proteins in adipocytes decreased germline stem cell maintenance, implicating a role for these proteins in adult tissue regulation.
