What is the origin of the cell line Int407? Is it colonic epithelial in origin or small intestinal epithelial or both? I have searched a lot but reports are highly confusing. Kindly help.
"Originally derived from the jejunum and ileum of a 2 month old Caucasian embryo...."
"This cell line has been found to be indistinguishable from HeLa by STR PCR DNA profiling. Therefore, the cells must be considered as derived from HeLa"
So it seems that whilst originally it was from a the intestinal area of a white foetus it has at some time been contaminated (and overtaken) by HeLa cells and is infact - HeLa.
So it is of Cervical Origin.
And indeed it is in the list of contaminated lines.
