Research Interests

Dr. Osol’s research interest is vascular adaptation during pregnancy, and addresses the following questions: (1) What are the mechanisms that regulate maternal uterine vascular remodeling during pregnancy, and how are they altered in hypertensive pregnancy? (2) What is the role of PlGF and VEGF in mediating these processes? (3) How do physical forces such as intravascular pressure/stretch regulate resistance artery tone (myogenic behavior)?  (4) What is the nature of communication/signal transfer between veins and arteries (venoarterial signaling)?  The rat is the primary animal model, and some of the experimental techniques used in the lab include: in vivo surgical manipulation of the uterus and its circulation; in vivo inhibition of cell signaling (e.g. NOS inhibition, ACE inhibition, calcium channel blockade); isolated pressurized vessel myography of resistance arteries and veins; molecular analyses (RT-PCR, Western blotting, immunocytochemistry); tissue/cell imaging for morphometric analysis, e.g. TEM, SEM, confocal microscopy.
