WebApr 13, 2024 · Abnormal angiogenesis caused by defects in the proliferation, migration, and invasion of trophoblast cells is one of the most important reasons for RSA. The microRNA (miRNA) is an important factor affecting cell proliferation, migration, and invasion. miRNAs are noncoding RNAs involved in regulating posttranscriptional gene silencing. WebCirculating trophoblasts (cTBs) are placenta-derived tropho- blast cells, predominantly of the extra-villous trophoblast (EVT) type, which shed into the maternal circulation during placental implantation and development20,21.
