TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Extravillous trophoblast (EVT) cell invasion plays a crucial role in establishment of successful pregnancy. CD44, a cell-surface receptor for hyaluronic acid (HA), plays a key role in HA-mediated remodeling and degradation that triggers cancer cell invasion. However, few studies have reported on the expression or functions of CD44 in human EVT cells. We hypothesized that CD44-HA interaction was involved in invasion by EVT cells.', 'To test our hypothesis, we conducted in situ examinations of CD44 and HA expression in the human first-trimester placenta. We also assessed the methylation status of CD44 promoter and exon 1 regions in EVT cells. Finally, we conducted transwell cell invasion assays using EVT cell lines and EVT cells isolated from first-trimester human villous explant cultures.'] Is extravillous trophoblast cell invasion promoted by the CD44-hyaluronic acid interaction?
OUTPUT:

agent
yes
