However, when using conventional transplantation methods, i.e., intrasplenic or portal venous infusion, it is difficult to control the engraftment efficiency and avoid unexpected engraftment in other organs because the transplanted cells are delivered into blood circulation before their liver engraftment.
Insulin delivered into peripheral circulation was assessed with the total area under the insulin concentration curve (AUCINS), calculated with the trapezoidal rule.
Although in this case there were no complications related to the chemotherapeutic agent being delivered into the cerebral circulation, the risk of injection into the cerebral circulation when selecting the ICA should be kept in mind.
The authors explained that the ECA was the preferred artery because of concerns that the chemotherapeutic agents could be delivered into the cerebral circulation when injecting into arterial feeders originating from the ICA [ 4].
Macrophages are the primary phagocytes in the body, which play a critical role in the clearance of particles delivered into the body's circulation.
We have also shown that prostate cancer cells delivered into the arterial blood circulation consistently lodge at the metaphysis of the distal femur and proximal tibia of inoculated animals [ 23, 27- 29].
Each vector was delivered into the portal venous circulation of adult C57BL/6 FIX /– mice (n=6 mice per group) at a dose of 4×10 VG/kg and in vivo expression of factor IX antigen (protein) and activity were assayed during 42 weeks of observation.
In addition, nearly comparable PDT activity to A549 cells for NSHB and HB confirms that the molecular design is successful and NSHB is readily delivered into target tissues via blood circulation after intravenous injection.
A relatively greater percentage of the total blood glucose lowering effect of insulin detemir is derived from its hepatic action, compared with that of exogenous human insulin delivered into the subcutaneous and systemic circulation (14, 15).
Our previous study has suggested that intestinal epithelial cells can take up plant miRNAs in food, pack them into MVs in a form in association with AGO2 complex and then release them into the circulation; the AGO2-associated plant miRNAs encapsulated in MVs are then delivered into different tissues/cells in which the miRNAs modulate the expression of their target genes.
