The use of fetal tissue in vaccine development is the practice of researching, developing, and producing vaccines through growing viruses in cultured (laboratory-grown) cells that were originally derived from human fetal tissue. [1] Since the cell strains in use originate from abortions, [2] there has been opposition to the practice and the ...
WI-38 cells (Left: in high density. Right: in low density) WI-38 is a diploid human cell line composed of fibroblasts derived from lung tissue of a 3-month-gestation female fetus. [1] [2] The fetus came from the elective abortion of a Swedish woman in 1963. The cell line was isolated by Leonard Hayflick the same year, [3] [4] and has been used ...
At 5 weeks, the embryo is a mass of cells with a developing neural tube (pre-spinal cord and brain). The forming fetus is no larger than a grain of rice.” Pregnancy tissue after an abortion at 5 ...
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. Several other COVID-19 vaccine candidates use fetal cell lines descended from fetuses aborted between 1972 and 1985. No fetal tissue is present in ...
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. [1] [2] The cell line was isolated by J.P. Jacobs and colleagues in September 1966 from the seventh population doubling of the original strain, and MRC-5 ...
On October 13, 2015, Planned Parenthood announced it would no longer accept reimbursement for the costs of collecting and shipping fetal tissue to research labs. Citing an "anti-abortion agenda" by some in Congress, Planned Parenthood stated the move was designed to remove a reason for politically motivated attacks.
Micrograph of products of conception. Chorionic villi (right of image) and cartilage, i.e. fetal parts (left of image). H&E stain. Products of conception, abbreviated POC, is a medical term used for the tissue derived from the union of an egg and a sperm. It encompasses anembryonic gestation (blighted ovum) which does not have a viable embryo .
Human embryonic kidney 293 cells, also often referred to as HEK 293, HEK-293, 293 cells, are an immortalised cell line derived from HEK cells isolated from a female fetus in the 1970s. [1] [2] The HEK 293 cell line has been widely used in research for decades due to its reliable and fast growth and propensity for transfection.
