May 2018 in “Nature” Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.
214 citations
,
April 2017 in “Cell” This study found that micro-niches within hair follicles create heterogeneity among stem cells and transit-amplifying cells, leading to specialized progenitors that control tissue morphogenesis and regeneration.
128 citations
,
August 2015 in “Cell Stem Cell” The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.
479 citations
