Research throws light on the mystery of why women are much more prone to autoimmune disorders: A molecule made by one X chromosome in every female cell can generate antibodies to a woman’s own tissues.
If it helps, the HeLa cell line, very popular in scientific research, comes from an African American woman: https://en.m.wikipedia.org/wiki/HeLa
I guess the reason for using only male cells in this case, might’ve been that if they’re running the test either on a self-replicating cell line, or on a heavily inbred strain of lab mice, where both X chromosomes are supposed to be “practically identical” due to the inbreeding, while one of them gets inactivated in females, then running a test on cells with both X and Y chromosomes, would already include “all there was to see”, with only half the work.
It’s interesting to see some advances in the understanding of the interaction of two X chromosomes, and how the result is not exactly the same as a single X.
The HeLa line had its own male-dominated issues, ie: denying her family a right to any money from the use of her genetics … which, once rectified, led to a signing away of any rights for people who have an interest in helping advance scientific and medical knowledge and/or treatments.
I know this because I was asked to become part of a study, but after reading the contract that clearly stated I (and my family/descendants) would be shut out of any and all financial compensation, I declined.
While I agree with this if/when a government agency or university developes treatments or cures, I do not agree with it when the info is given freely to for-profit big pharma for them to make trillions from.
