For the worldwide beauty market with products like skin cremes et al, that use various combinations of HEK (Human embryonic kidney). EDIT: There is also a massive market for in-utero organs, corneas, skin, nerves etc for use in scientific and medical research through funding by major universities. Every once in a while an expose appears in the msm of researchers not 'buying' the 'biological research material' through approved channels. It can range from several hundred to several thousand dollars per piece especially when researchers become very specific about wanting un-damaged goods freshly removed from an aborted fetus meeting different requirements like gestation age, race, parental eye color etc .
