Benedict argued that non-conjugal reproduction such as in vitro fertilization had created «new problems» ¯ the freezing of human embryos, for instance, and the selective abortion of medically implanted embryos, together with pre-implantation diagnosis, embryonic stem - cell research, and attempts at human cloning.
The National Institutes of Health (NIH) has allowed a contract for the dissemination of embryonic stem cell lines approved for US government funding to lapse, shuttering a key stem cell bank, and doubling the price researchers pay for samples of some human embryonic stem cell (hESC) line... from $ 500 per vial of frozen cells to $ 1,000.
«Maybe at the one - cell or two - cell stage,» Eggan and his colleagues reasoned, «there's still some of that stuff in there...» And if they picked the right moment of cell division, when these powerful reprogramming factors were still floating around in the periphery of the cell, they might be able to use drugs to temporarily freeze the cell in the middle of division, stick in the needle of a micromanipulator to suck out the embryonic DNA, squirt in DNA from an adult animal, and then kick - start the process of reprogramming — hours, perhaps even days after an egg had been fertilized.
By contrast, embryonic stem cells are culled from embryos created and frozen in fertility labs.
Because fertilized human embryos are far more accessible than unfertilized eggs, which can not be frozen and stored, extending the result to humans could lower the practical barriers against creating human embryonic stem cells to study and potentially treat disease.

Human pluripotent stem cells (hPSCs), including human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs), are known to be vulnerable to apoptosis upon various technical manipulation, such as single cell dissociation, freezing and thawing, etc., which hinder their use for clonal isolation in gene transfer, differentiation and FACS cell sorting.
However, some consider human embryonic stem cell research controversial because, in some cases, the new stem cell lines are derived frozen human embryos that have been donated for research.
