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 ...
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 ...
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 ...
A zoster vaccine is a vaccine that reduces the incidence of herpes zoster (shingles), a disease caused by reactivation of the varicella zoster virus, which is also responsible for chickenpox. [8] Shingles provokes a painful rash with blisters, and can be followed by chronic pain ( postherpetic neuralgia ), as well as other complications.
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.
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.
Microchimerism. During pregnancy, a two-way traffic of immune cells may occur through the placenta. Exchanged cells can multiply and establish long-lasting cell lines that are immunologically active even decades after giving birth. Microchimerism is the presence of a small number of cells in an individual that have originated from another ...
Chr. 11 p15.4. Fetal hemoglobin, or foetal haemoglobin (also hemoglobin F, HbF, or α2γ2) is the main oxygen carrier protein in the human fetus. Hemoglobin F is found in fetal red blood cells, and is involved in transporting oxygen from the mother's bloodstream to organs and tissues in the fetus. It is produced at around 6 weeks of pregnancy ...
