The characterisation of stem cells is of vital importance to regenerative medicine. Failure to separate out all stem cells from differentiated cells before therapies can result in teratomas - tumours of multiple cell types. Typically, chara...
Raman spectroscopy as a potentialmethod for the detection of extremely halophilic archaea embedded in halite in terrestrial and possibly extraterrestrial samples [0.03%]
拉曼光谱作为一种潜在的方法用于检测嵌入盐岩中极端嗜盐古菌的痕迹（来自地球或其它地方的样本）
Sergiu Fendrihan,Maurizio Musso,Helga Stan-Lotter
Sergiu Fendrihan
Evidence for the widespread occurrence of extraterrestrial halite, particularly on Mars, has led to speculations on the possibility of halophilic microbial forms of life; these ideas have been strengthened by reports of viable haloarchaea f...
