A "unique" service, indeed.
From http://www.stemlifeline.com/
"StemLifeLine is proud to offer a unique service to individuals who have undergone in vitro fertilization. Until now, there have been only three options for embryos remaining after individual childbearing needs have been fulfilled. They could be donated to research, given up for “adoption” to other couples or discarded. We provide a fourth option for these embryos which is to generate personal stem cell lines that can one day be used to create personal therapies.

StemLifeLine derives and cryopreserves stem cells from remaining stored embryos. Derivation of stem cell lines from human embryos is a highly sophisticated and delicate process which requires state-of-the-art cell culture facilities and a skilled staff.
Derivation basics
Stem cell derivation is a process that takes several months and entails isolating, growing and characterizing the stem cells from the embryo. Through the derivation process, StemLifeLine preserves the viability of the cells within the embryo by growing them as stem cells. The embryos are essentially transformed into the resulting stem cell lines. "
What those folks who seek these services probably doan know is that
they ain't had no success wif any embryonic stem cells--

all the success stories is wif' adult stem cells...so why does we need ter cannibalize baby embryos in hopes of gainin' immortality?
We'uns is headed into a cold wasteland. Soon enough, we'll be told why "inferior" children ought not live (as Dr. Peter Singer already advocates) and as manipulation fantasies multiply like rats, the definition of "inferior" will grow to include "conditions" such as pigeon toes an' singin' off key.
