Does culture of cells from maternal circulation , in conditions favoring fetal endothelial cell expansion , facilitate the preferential expansion of circulating fetal cells?
Optimal concentrations of CSF-1, PlGF and TGF-beta1 for preferential expansion of fetal endothelial cells were determined in model cultures. However, when these conditions were applied to maternal blood samples, no fetal cells could be detected based on PCR for SRY in women carrying male fetuses.
Although nearly all of our subjects admitted that their children had a regular source of care, many parents showed evidence of lack of knowledge of CSS and airbag safety. Furthermore, many parents were not familiar with the state law regarding child restraints. Our findings suggest that parents of small children who utilize emergency care services could benefit from child passenger safety education during their ED visit and that non-English media and materials may be important to reaching this population.
