In humans and mice, EPC levels are decreased upon exposure to elevated levels of PM2.5.
In particular, β2-integrins are essential for homing and improvement of neovascularization mediated by EPCs after hind limb ischemia in mice.
The results showed EPC cultures in the presence of ox-LDL contained significantly fewer EPCs after 18 hours compared with control (OD450: 0.700 ± 0.046 versus 1.119 ± 0.031; P < 0.01)).
However, there is no report on the change of EPCs after glycemic control.
There is no clear consensus on the accurate definition of EPCs after all [ 10].
The first strategy represents the only way to immediately isolate EPCs after sample collection.
Similar effects were shown also in grafting of human cord blood-derived EPC nude mouse model with EPCs limb ischemia [ 27].
Subsequently, blood flow increased gradually to a level of 81.2±2.9% (EPC-CM) and 83.7±3.0% (EPC) after five weeks (P = n.s. between the two treated groups; Figure 4A, B).
Shear stress may be suggested as a triggering factor for EPCs release after a single NMES session.
EPCs obtained after isolation generally adhere to culture plates within 6 to 8 hours of isolation.
