Bone marrow (BM)-derived progenitor cells (BMDPCs) are known to migrate and give rise to endometrial cells however their functional contribution to implantation and pregnancy are unknown . Here we show that implantation and pregnancy are strong stimuli for BMDPCs recruitment to the uterine decidua where BMDPCs differentiate into functional non-hematopoietic prolactin-producing decidual cells. Transcriptome analysis of implantation sites demonstrated that Hoxa11+/- mice transplanted with WT BM clustered hierarchically more closely with normal WT mice than with control Hoxa11+/- mice, showing normalized expression of numerous implantation-related genes. These findings reveal that BMDPCs have a major non-hematopoietic physiologic contribution to the decidual stroma, and thereby play an essential and previously unproven role in the establishment and maintenance of pregnancy.
