The simplest way: trypan blue. Dead cells stain blueNon-fixed cells: FDA(fluorescein diacetate)-green, alive cells; P.I. (propidium iodide)-red, dead cells35 mm plates:Note:If the P.I. staining is not strong enough to be picked up easily under your scope, use 2 X P. I., i.e., 4 ul 2 mg/ml in 2 ml mediumAfter staining, need to examine the staining right away, otherwise, the green staining gets diffused. You ......閱讀全文

Cell－death－＆diffe：CR1調控結腸癌腫瘤干細胞功能
近日，國際期刊cell death＆differentiation 在線發表了意大利科學家的一項最新研究進展，他們發現胚胎期蛋白Cripto-1（CR1）在結腸癌腫瘤干細胞中表達能夠促進腫瘤干細胞的克隆形成，這項研究表明CR1可能通過促進結腸癌腫瘤干細胞生長導致結腸癌復發。 最近，細胞干
