| Summary |
Maternal fetal immune tolerance is a biological event that plays a key role in pregnancy. In particular, the mechanism by which the maternal immune system does not exclude the semi-identical antigen of the fetus has not been fully answered so far. The most serious result of the maternal fetal immune tolerance balance is the recurrent spontaneous abortion (RSA). The fetus is rejected by the mother in the early pregnancy and cannot continue to develop in the uterus. Based on these scientific questions, we used single-cell sequencing technology to analyze nearly 30,000 leukocytes in the decidua of normal and RSA. A total of 13 immune cell subsets were found, of which dNK cells were more prominent, The lineage differentiation pathway of dNK cells was excavated, and the pathological role of dNK differentiation abnormality in the occurrence of RSA was analyzed. Our results deepen our understanding of the differentiation and function of human decidual leukocytes, especially dNK cells. We clearly recognize that the immune system has dynamic changes compared with normal pregnancy under pathological conditions, which is likely to occur in RSA. The important factors, we expect our results to provide a new basis for RSA's immune diagnosis and treatment strategy.

| Overall design |
Single cell sequencing on decidual immune cellss was performed from normmal pregnancy women and recurrent spontaneous abortion (RSA) patients. CD45+ leukocytes were sorted from decidua at early pregnancy period through MoFLo XDP.
