The WI-38 cell line stemmed from earlier work by Hayflick growing human cell cultures. [2]In the early 1960s, Hayflick and his colleague Paul Moorhead at the Wistar Institute in Philadelphia, Pennsylvania discovered that when normal human cells were stored in a freezer, the cells remembered the doubling level at which they were stored and, when reconstituted, began to divide from that level to ...
Immortalised cell lines are an important research tool offering a stable medium for experiments. These are derived either from tumors, which have developed resistance to cellular senescence, or from stem cells originally taken from aborted fetuses. [10] Fetal cell lines have been used in the manufacture of vaccines since 1930s. [11]
MRC-5 cell. MRC-5 (Medical Research Council cell strain 5) is a diploid cell culture line composed of fibroblasts, originally developed from the lung tissue of a 14-week-old aborted Caucasian male fetus.
In a sharply worded dissent Thursday, Justice Clarence Thomas expressed support for the plaintiffs’ debunked claims that all Covid vaccines are made with cells from “aborted children.”
In December, Pope Francis said taking vaccines derived from aborted cells could be "morally acceptable." Bishops urge Catholics to avoid the Johnson & Johnson vaccine if possible because it was ...
Rick Perry said "The video showing a Planned Parenthood employee selling the body parts of aborted children is a disturbing reminder of the organization's penchant for profiting off the tragedy of a destroyed human life", [14] and cited the videos as the reason why Planned Parenthood should lose federal funding.

While it is true that cell lines derived from a fetus aborted in 1970 plays a role in the vaccine development process, the molecules for the vaccine are separated from the resulting cell debris. [72] [73] Several other COVID-19 vaccine candidates use fetal cell lines descended from fetuses aborted between 1972 and 1985. No fetal tissue is ...
HEK 293 cells were generated in 1973 by transfection of cultures of normal human embryonic kidney cells with sheared adenovirus 5 DNA in Alex van der Eb's laboratory in Leiden, the Netherlands. The cells were obtained from a single, aborted or miscarried fetus, the precise origin of which is unclear.
