Promyelocytic leukaemia zinc finger (Plzf), also known as zinc finger and BTB domain containing 16 (ZBTB16) or zinc-finger protein 145 (ZFP145), is a critical zinc finger protein of male germline stem cells (mGSCs). Multiple lines of evidence indicate that Plzf has a central role in the development, differentiation and maintenance of many stem cells, including mGSCs, and Plzf has been validated as an essential transcription factor for mammalian testis development and spermatogenesis. This review summarises current literature focusing on the significance of Plzf in maintaining and regulating self-renewal and differentiation of mGSCs, especially goat mGSCs. The review summarises evidence of the specificity of Plzf expression in germ cell development stage, the known functions of Plzf and the microRNA-mediated mechanisms that control Plzf expression in mGSCs.

Asymmetric stem cell division is often accompanied by stereotypical inheritance of the mother and daughter centrosomes. However, it remains unknown whether and how stem cell centrosomes are uniquely regulated and how this regulation may contribute to stem cell fate. Here we identify Klp10A, a microtubule-depolymerizing kinesin of the kinesin-13 family, as the first protein enriched in the stem cell centrosome in Drosophila male germline stem cells (GSCs). Depletion of klp10A results in abnormal elongation of the mother centrosomes in GSCs, suggesting the existence of a stem cell-specific centrosome regulation program. Concomitant with mother centrosome elongation, GSCs form asymmetric spindle, wherein the elongated mother centrosome organizes considerably larger half spindle than the other. This leads to asymmetric cell size, yielding a smaller differentiating daughter cell. We propose that klp10A functions to counteract undesirable asymmetries that may result as a by-product of achieving asymmetries essential for successful stem cell divisions.
