The application of human embryonic stem (ES) cells in medicine and biology has an inherent
reliance on understanding the starting cell population. Human ES cells differ from mouse …

Recent reports have suggested that mammalian stem cells residing in one tissue may have
the capacity to produce differentiated cell types for other tissues and organs 1 – 9 . Here we …

A preference for n-parffins with odd numbers of carbon atoms is widespread in Recent
