An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Spore-like cells were proposed to be pluripotent cells that lie dormant in animal tissue and become active under stress or injury as adult stem cells, exhibiting behavior characteristic of spores. They were proposed in 2001 by brothers Charles and Martin Vacanti and colleagues. Further work in collaboration with Japanese researchers led to the apparent discovery of STAP cells, in which the pluripotent cells were newly created by stress or injury. This work was published in 2014, but soon found to be due to fraudulent work by Haruko Obokata.

  • 胞子様細胞(ほうしようさいぼう、英: Spore-like cells)は、胞子に特徴的な振舞いを示す細胞としてチャールズ・バカンティらが2001年に発表した仮説である。 論文では、既知の胞子様細胞には、ヒトを含む成体の特定の種類の幹細胞があり、これらは非常に小さく、非常に多能で、その他の生物の細胞が分裂、成長、死亡するのに対して休眠した「胞子様」状態のままで留まっていると主張。更に休眠状態にもかかわらず、この細胞は成長、分裂、そして他の細胞種に分化する能力を維持していると考えていた。 2001年の論文は説明や証明が不十分で研究は懐疑的に見られており、2011年に発表された多能性を検証した論文についても、撤回すべき程の画像の修正や科学的な疑義が生じている。 (ja)
