The Colorado lab discovered that granulosa cells — the cells that surround maturing eggs in the ovarian follicles — were pumping out leptin and shipping it into the egg.

And with that, he began prying away the granulosa cells clinging to the eggs, in order to get a better microscopic view of the nascent embryos to see if they were developing properly.

From the time an egg begins to develop in one of a woman's ovaries, the granulosa cells serve as a communication system — signaling, for example, when the egg needs nutrients and proteins.

If you believe, for example, that granulosa cells and other very early features of ovarian ecology set up the polarities that ultimately determine the quality of a human egg, as Albertini does, then certain techniques widely used in IVF may be subtly perturbing the very mechanisms that eggs use to establish a plan to build an embryo and maximize the chances that it will develop properly.

Van Blerkom had been seeing hints of polarity since the 1970s, but one of the major turning points occurred in 1996 when, by accident, his lab discovered that cells surrounding the developing egg — the same granulosa cells that had piqued Albertini's interest — possessed a receptor very similar to the leptin receptor.
