You can go your own way: State regulation of oocyte donation in California and New York

State regulation of oocyte donation in the context of human embryonic stem cell (hESC) research has increased since California's landmark passage of Proposition 71 and the establishment of the first state-funded stem cell agency, the California Institute for Regenerative Medicine (CIRM). Scholarship has largely focused on California's regulation of stem cell research as a patchwork of private sector and state regulations, reflecting major debates about the social contract for science. Given California's political exceptionalism, how does examining alternative state histories, political structures, and institutions at the state level illuminate the ways that bio-innovation is being regulated in a federal regulatory vacuum? Examining state management of oocyte donation in the context of hESC research, this article considers New York and California as comparative sites of stem cell science regulation, which enriches our understanding of how regulation of stem cell science arises out of an engagement with representative politics and the private sector in the United States. Employing a process tracing of policy development in New York and California, this article highlights alternative democratic pathways to the management of oocyte donation in research contexts: given differences in direct democratic action, legislative representation, executive leadership, and publicly funded state stem cell research institutions, distinct regulatory outcomes occur with important bioethical implications for publics and participants in stem cell science at the state level.
