my understanding is that embryos aren't the primary source of stem cells anymore and all of these jurisdictions are satisfied

Embryonic stem cells are one of the main sources, but not the only ones. Embryonic stem cells are derived from embryos that are 3-5 days old. These cells have the ability to develop into all cell types in the body. However, due to ethical concerns and the limited availability of human embryos, researchers have also developed methods to create induced pluripotent stem cells (iPSCs). iPSCs are adult cells that have been reprogrammed to behave like an embryonic stem cell. They can be generated directly from adult tissues, such as skin or blood cells. Another source of stem cells is the umbilical cord blood and tissue, which is rich in hematopoietic stem cells. Adult (or somatic) stem cells are also present in various tissues in our body, such as bone marrow and fat.

and here is a wiki and non-wiki source I found on iPSCs just in case the LLM made up an acronym. https://en.wikipedia.org/wiki/Induced_pluripotent_stem_cell
