Relative to the HG + HF + Exos group, increased MALAT1 but decreased miR-382-3p were seen in the HG + HF + AE + Exos group; relative to the HG + HF + AE + Exos + DMSO group, decreased MALAT1 but increased miR-382-3p were found in the HG + HF + AE + Exos + GW4869 group (Fig. 5A). Here, MALAT1 is linked to hydrops fetalis.
