Abstract
- Background: Numerous pathologies of pregnancy originate from placental dysfunction. It is essential to understand the functions of key genes in the placenta in order to discern the etiology of placental pathologies. A paucity of animal models that allow conditional and inducible expression of a target gene in the placenta is a major limitation for studying placental development and function. Results: To study the platelet‐derived growth factor receptor alpha (PDGFRα)‐directed and tamoxifen‐induced Cre recombinase expression in the placenta, PDGFRα‐CreER mice were crossed with mT/mG dual‐fluorescent reporter mice. The expression of endogenous membrane‐localized enhanced green fluorescent protein (mEGFP) and/or dTomato in the placenta was examined to identify PDGFRα promoter‐directed Cre expression. Pregnant PDGFRα‐CreER;mT/mG mice were treated with tamoxifen at various gestational ages. Upon tamoxifen treatment, reporter protein mEGFP was observed in the junctional zone (JZ) and chorionic plate (CP). Furthermore, a single dose of tamoxifen was sufficient to induce the recombination. Conclusions: PDGFRα‐CreER expression is restricted to the JZ and CP of mouse placentas. PDGFRα‐CreER mice provide a useful tool to conditionally knock out or overexpress a target gene in these regions of the mouse placenta. Key Findings: Inducible PDGFRα‐directed Cre expression trophoblasts cells.A single tamoxifen treatment is sufficient to induce the recombination.Valuable tool to temporary knockout or over‐express a target gene in the placenta.Do not require sophisticated system and suitable for ordinary laboratory setting.
