Compliance with Ethical Standards
:
: The authors declare that they have no conflict of interest.
: This article does not contain any studies with human participants or animals performed by any of the authors.
: None. Our research involves non-human subjects, so informed consent is not applicable. We did not have in vivo experiments (did not have animal study), so the ethical certificate is again not applicable. Just for human mesenchymal bone marrow stem cells (MSC, BN_0012.1.11), we purchased from Bonyakhteh (a research center, under the supervision of the Iran Health Organization and has a license), which is authenticated.
