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).

Condition Intervention
Pregnant Women
Other: blood donation

Study Type: Observational
Official Title: microRNA Profile in Umbilical Cord Blood NK Cells

Further study details as provided by National Taiwan University Hospital:

Biospecimen Retention:   Samples With DNA

Umbilical cord blood

Estimated Enrollment: 5
Study Start Date: September 2008
Estimated Study Completion Date: September 2009
Groups/Cohorts Assigned Interventions
A group of 3 to 5 pregnant women as donors for umbilical cord blood
Other: blood donation
obtaining cord blood
Other Name: cord blood donation

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.
