Prize for the HeLa cell story
A widely acclaimed debut book, published this year, has won the prestigious Wellcome Trust book prize, announced last month. The book tells the story of a poor southern tobacco farm worker whose cancer cells, taken without her or her family’s knowledge, became one of the most important tools in cell biology and medicine. When Henrietta Lacks was dying from cervical cancer in a Baltimore hospita...
متن کاملCanadian Stem Cell Scientists Take the Prize
This year, the recipients of the Lasker Award for Basic Medical Research are Ernest A. McCulloch and James E. Till. The landmark studies of McCulloch and Till in the 1960s defined the hallmark properties of stem cells: the ability to self-renew and differentiate.
متن کاملHela Cell Plasma Membranes
A method for the preparation of HeLa cell plasma membrane ghosts is described. The purity of the plasma membrane fraction was examined by phase contrast and electron microscopy, by chemical analysis, and by assay of marker enzymes. Data on the composition of the plasma membrane fraction are given. It was observed that the distribution pattern of 5'-nucleotidase activity among the subcellular fr...
متن کاملEditorial: HeLa Cell Sequela
Free and informed consent of participants in research studies is a cornerstone of biomedical research, but this has not always been the case. Cells derived from tumor tissue of an American woman without her consent more than 60 years ago and named HeLa cells were eventually identified as belonging to Henrietta Lacks, a fact that became widely known in 2010 upon publication of a bestselling book...
متن کاملA Chemical Method for the Isolation of Hela Cell Nuclei and the Nuclear Localization of Hela Cell Alkaline Phosphatase
Several chemical methods for the isolation of cell nuclei have recently been described. Calf thymus nuclei have been isolated by mild hypotonic shock followed by Ficoll gradient purification (1). A nonaqueous technique has been employed by Hammel and Bessman for purifying duck erythrocyte nuclei (2). Cell nuclei from cat brain have been obtained by using a detergent, Tri ton X-100, which result...
