The distance the CD34+ EPC migrates in response to SDF1 alpha 10ng. This assess the mobility of stem cells such as CD34+ EPC and the distance it traveled would lead us to understand how medication therapy changes stem cell behavior and its functionality.

Population: Due to freezer power failure in the lab, the fat samples were degraded and could not saved for cryo preservation. As a result, qpcr and histology could not carried out due to lack of samples in frozen state.

We will evaluate mRNA gene expression for mature fat and fat related transcription factors.

Timeframe: First Visit at Baseline and Last Visit at 24 weeks

Vessel health is assessed by looking at Arterial stiffness. Augmentation index (AI) is defined as the ratio of the augmentation pressure to the pulse pressure, times 100, to give a percentage. We used Vascular Flow and wave measurement equipment, SphygmoCor Central Pressure system from AtCor. The higher the values the higher the cardiovascular risk.

Vessel health is assessed by looking at Arterial stiffness. Augmentation index (AI) is defined as the ratio of the augmentation pressure to the pulse pressure, times 100, to give a percentage. Augmentation index 75 normalizes this value to an estimate of the AI at a heart rate of 75bpm. We used Vascular Flow and wave measurement equipment, SphygmoCor Central Pressure system from AtCor. The higher the values the higher the cardiovascular risk.
