Human Based Stem Cell Culture Medium Developed 133
ubersonic writes "A new culture medium for growing human stem cells -- that contains no animal products -- is offering researchers a cleaner and therefore safer environment for performing the cutting-edge technology.
The discovery means that stem cells developed for therapeutic use can be transferred directly to human subjects. By using this medium all of the concerns about contaminating proteins in existing stem cell lines can essentially be removed."

I am sorry but there is nothing "besides" or "outside" life/living. You're implying the existance of some sort of sentient being who would suffer under certain conditions and would like a different treatment: but such sentient being, by your very definitions of the circumstances (not being born at all), cannot exist. You're kinda condraticting yourself. So, to answer: *I* wouldn't find it funny to be turned into a treatment; but it's the real, living, *I* that speaks here.
