- The trouble with embryos. Baylis, Fran�oise; Krahn, Timothy // Science Studies;Dec2009, Vol. 22 Issue 2/3, p31
In an effort to quell ongoing debate about the ethics of human embryonic stem cell (hESC) research, there have been concerted efforts to develop ethical standards for both embryo and hESC research and to entrench these standards in law. Surprisingly these efforts have not included efforts at...

Background: The reverse transcriptase of telomerase (Tert) controls telomerase activity maintaining the end of linear chromosomes in eukaryotic cells. Telomerase function is highly active in undifferentiated multipotent stem cells, decreases with cell differentiation and is generally absent from...
- The ethics of using embryos in research. G., Pennings // Reproductive BioMedicine Online;Apr2008 Supplement 3, Vol. 16, pS-14
The discussion on the use of embryos for research was rekindled by the discovery of the potential of embryonic stem cells. Embryo research and stem cell research are inextricably linked. The question whether embryos can be used for research is analysed by starting from three questions: (i) is...
