Studysummary In this study, the researchers found that depleting natural polyamines or manipulating translation rates can enhance the stemness of hair follicle stem cells, while N1-acetylspermidine increases proliferation without affecting translation.

The study from April 2020 investigated the role of polyamines in hair follicle stem cell (HFSC) fate decisions. It found that HFSCs had lower translation rates than progenitor cells, and that suppressing translation either by directly targeting the ribosome or depleting natural polyamines increased stemness. The study also identified N1-acetylspermidine as a new regulator of cell fate decisions, which could increase proliferation without reducing translation. This suggests that polyamines play a significant role in regulating stem cell fate decisions, with potential implications for hair growth and loss.
