Abstract
Background
Recently, cold atmospheric plasma (CAP), as well as adipose mesenchymal stem cells derived exosomes (ADMSCs-EX), have been applied separately to wound healing treatment. However, no study has investigated the additive effect on the healing mechanism of these two methods in the same skin lesion treatment model.
Aim
We conduct this study to describe the results of using CAP and human ADMSCs-EX on in vitro wound healing.
Methods
Exosomes were isolated from donor adipose tissue samples by ultracentrifugation method, characterized by transmission electron microscopy (TEM) and Western blot. Assessment in vitro wound healing on proliferation and migration evaluation experiments on human fibroblasts with culture medium supplemented with 10µg total exosomal proteins/1 mL and irradiated with CAP with an intensity of 30 seconds/cm2.
Results
Experimental results to evaluate the ability to stimulate fibroblast migration, showed that cell migration speed in the group supplemented with ADMSCs-EX was equivalent to the group with a combination of CAP and ADMSCs-EX and had the highest rate with 87.8 ± 4.2 % and 84.4 ± 5.3 % while in the control group it was the lowest with 61.9 ± 11.4% (p<0.05). The group supplemented with CAP gave fibroblast proliferation and migration results similar to the control group (p>0.05), showing the safety of CAP with the growth of the cells.
Conclusions
Therefore, in animal models, we intend to use a combination of these two therapies by using ADMSCs-EX injection therapy into the dermis at the wound edge to avoid the impact of CAP affecting the cell proliferation.
