WebAbstract. Cell cultures represent relevant and useful experimental models of transmissible spongiform encephalopathies (TSEs). They are able to promote, upon subpassaging, stable and persistent replication of PrP (Sc) as well as infectivity. To date, only a few cell culture models permissive to prion replication are available. WebHowever they tend to see the primary stuff in the universe as having both matter-like and spirit-like qualities. The paleontologist and Jesuit priest Pierre Teilhard de Chardin, who was born in 1881, a year before Darwin died, was one of the first to combine spirituality and evolution in an emergence framework.
