Abstract

Objective:

To investigate the role of heart and neural crest derivatives–expressed transcript 2 (HAND2) during decidualization of human endometrial stromal cells (ESCs).

Design:

In vitro experiment.

Setting:

Research laboratory.

Patient(s):

Twenty-six patients undergoing hysterectomy for benign reasons.

Intervention(s):

ESCs were cultured for 12 days with HAND2 small interfering RNA (siRNA) or nonsilencing RNA during decidualization by medroxyprogesterone acetate (MPA) and E2.

Main Outcome Measure(s):

Decidualization was monitored by changes in cellular morphology and the expression of several decidual-specific genes.

Result(s):

HAND2 siRNA effectively suppressed HAND2 levels in ESCs after 12 days of E2 + MPA treatment. ESCs cultured with HAND2 siRNA retained a long fibroblast-like shape, whereas the cells cultured with control siRNA transformed into enlarged polygonal cells. Silencing of HAND2 expression significantly reduced connexin-43 involved in the morphologic changes. HAND2 silencing significantly reduced the mRNA levels of fibulin-1, prolactin, tissue inhibitor of metalloproteinase 3, interleukin-15, and forkhead box O1A (FOXO1A), but had no effect on the mRNA levels of dickkopf-1, serum glucocorticoid kinase 1, and insulin-like growth factor–binding protein 5. HAND2 siRNA effectively suppressed the levels of nuclear FOXO1A protein as a regulator of decidualization.

Conclusion(s):

These results suggest that HAND2 plays a key role in the regulation of progestin-induced decidualization of human ESCs.
