Human bone marrow mesenchymal stem cell-derived exosomes loaded with gemcitabine inhibit pancreatic cancer cell proliferation by enhancing apoptosis

Table 1 The encapsulation and loading efficiencies of three different methods

	Ultrasonication	Electroporation	Incubation
Encapsulation efficacy (%)	8.1 ± 0.8c	7.6 ± 1.0c	1.2 ± 0.3
Loading efficiency (%)	4.3 ± 0.4c	4.0 ± 0.5c	0.6 ± 0.2

^cP < 0.001 vs incubation group.

Data are presented as mean ± SD (n = 3) of a representative experiment performed in triplicate.
