HEK 293 cells cell, all of which are abundant in kidneys. However, the original adenovirus transformation was inefficient, suggesting that the cell that finally produced the HEK 293 line may have been unusual in some fashion. Graham and coworkers provided evidence that HEK 293 cells and other human cell lines generated by adenovirus transformation of human embryonic kidney cells have many properties of immature neurons, suggesting that the adenovirus preferentially transformed a neuronal lineage cell in the original kidney culture. A comprehensive study of the genomes and transcriptomes of HEK 293 and five derivative cell lines compared the HEK 293 transcriptome with that
The 85 Ways to Tie a Tie The 85 Ways to Tie a Tie The 85 Ways to Tie a Tie () is a book by Thomas Fink and Yong Mao. The authors were research fellows at Cambridge University’s Cavendish Laboratory. It was published by Fourth Estate on Nov 4, 1999, and subsequently published in nine other languages. "The 85 Ways to Tie a Tie" is about the history of the knotted neckcloth, the modern necktie, and how to tie both. It is based on two mathematics papers published by the same authors in the journals Nature and Physica A. The authors prove there are exactly 85
