African-American woman (1920–1951), source of HeLa immortal cell line "Lacks" redirects here. For other uses, see Lack. Henrietta Lacks Lacks c. 1945–1951. Born Loretta Pleasant (1920-08-01) August 1, 1920 Roanoke, Virginia, U.S. Died October 4, 1951 (1951-10-04) (aged 31) Baltimore ...
HeLa cells have also been used to define cancer markers in RNA, and have been used to establish an RNAi Based Identification System and Interference of Specific Cancer Cells. [44] In 2014, HeLa cells were shown to provide a viable cell line for tumor xenografts in C57BL/6 nude mice, [45] and were subsequently used to examine the in vivo effects ...
As a cancer researcher who uses HeLa cells in my everyday work, even I sometimes find it hard to believe. ... On Aug. 1, 2023, over 70 years after doctors took Lacks’ cells without her consent ...
The cells, later known as HeLa cells, grew at an astonishing rate in the lab and were shipped and sold to researchers for various purposes. Research with the cells helped to facilitate medical breakthroughs, including the vaccines for polio and human papillomavirus , though controversy later arose because the cells were being used without the ...
The estate of Henrietta Lacks filed a lawsuit in Maryland federal court on Thursday accusing biopharmaceutical company Ultragenyx Pharmaceutical of unlawfully profiting from cells that were taken ...
Because of this, they were considered the first “immortal” cell line, allowing scientists to cultivate her cells and use them in biomedical research. HeLa cells are the oldest and most widely ...

Since the use of genetic markers to characterize and distinguish cell lines at the time was virtually non-existent ...
When Hela cells were transfected with the HSV-tk gene, and were then put in a culture with nontransfected cells, only the HSV-tk transfected Hela cells were killed by the granciclovir, leaving the nonviral cells unharmed. [136] The Hela cells were transfected with the encoding for the gap junction protein connexin 43 (Cx43) to provide a channel ...
