“ How do you ‘properly consent’ to, and, ‘ethically’ obtain human embryo cells?”
———————————————————————————
Not sure what the criteria is (vaginal birth vs. C-Section) but mother’s giving birth are asked if they consent to donating their umbilical cord blood for research.
It’s very common nowadays.
Inside the umbilical cord the blood contains embryo cells.

Human Embryonic Stem Cells

Stem cells are undifferentiated cells that are capable of dividing for long periods of time and can give rise to specialized cells under particular conditions. Embryonic stem cells are a particular type of stem cell derived from embryos. According to US National Institutes of Health (NIH), in humans, the term “embryo” applies to a fertilized egg from the beginning of division up to the end of the eighth week of gestation, when the embryo becomes a fetus.
Between fertilization and the eighth week of gestation, the embryo undergoes multiple cell divisions. At the eight-cell stage, roughly the third day of division, all eight cells are considered totipotent, which means the cell has the capability of becoming a fully developed human being.
By day four, cells begin to separate and form a spherical layer which eventually becomes the placenta and tissue that support the development of the future fetus. A mass of about thirty cells, called the inner cell mass, forms at one end of the sphere and eventually becomes the body.
When the sphere and inner cell mass are fully formed, around day 5, the pre-implantation embryo is referred to as a blastocyst. At this point the cells in the inner cell mass have not yet differentiated, but have the ability to develop into any specialized cell type that makes up the body. This property is known as pluripotency.
As of 2009, embryonic stem cells refer to pluripotent cells that are generally derived from the inner cell mass of blastocysts.....

Difference Between Umbilical Cord Stem Cells and Embryonic Stem Cells
....Summary – Umbilical Cord Stem Cells vs Embryonic Stem Cells
Umbilical cord stem cells and embryonic stem cells are two types of important stem cells. Umbilical cord stem cells include both umbilical cord tissue and blood stem cells which are undifferentiated cells. They can be differentiated into several types hence they are multipotent. Embryonic stem cells are the undifferentiated cells isolated from five to eight days old embryo developed by in vitro fertilization. They are pluripotent and can be specialized into many cell types in the human. This is the difference between umbilical cord stem cells and embryonic stem cells....
(Lots of explanatory info, at above link, in case you want to learn MORE about the difference.)
You’re deliberately confusing the issue.
The cord blood is prized for the stem cells which are used (for example) for Leukemia patients.
The issues there are finding a good enough match (even though you don’t need as stringent a match to the patient with cord blood cells as with adult marrow cells); low total volume of cells; and defraying of keeping the cord cells at liquid nitrogen temperature until there is a match...and of older lots didn’t have typing done to the same level of detail as is now available; course, due to small sample size (see above), it’s just not worth it to take another sample from the same donation of cord blood and do a more thorough test.
