microRNA Profile in Umbilical Cord Blood NK Cells
An observational study of Pregnant Women, run by National Taiwan University Hospital at 1 site in Taiwan.
Trial summary
Umbilical cords contain immature blood cells, including a group of lymphocytes, that are important in the so-called natural immunity. We want to study the cytokine levels in umbilical cord NK cells and its regulation a family of newly identified small RNAs (microRNAs). Read more about this study

About this study
Umbilical cords contain immature blood cells, including a group of lymphocytes, that are important in the so-called natural immunity. We want to study the cytokine levels in umbilical cord NK cells and its regulation a family of newly identified small RNAs (microRNAs).
Read the detailed description
Our preliminary data pointed to the possibility of cytokine regulation by microRNAs in NK lymphoma and NK lymphoma cell lines. We want to use umbilical cord blood as controls for the biological significance in normal NK cell development.
