However, recurring problems in heterologous expression of these clusters are low production efficiencies and unpredictable gene expression levels, often due to cryptic regulatory elements.
Based on this frequently recurring observation and the high expression of Prox1, we speculate that the contact sides between pTD and CV might develop into first valves, allowing the developing lymphatics to become functional by preventing backflow from the venous circulation into the nascent lymphatic vasculature.
