Abstract
Objective Migratory speed rate evaluation of human dental pulp stromal cells (hDP-SCs) is one
of the important steps in dental pulp regeneration. Therefore, the aim of the study
is to analyze various concentrations of advanced platelet-rich fibrin (A-PRF) culture
media toward hDP-SCs' migratory speed rate evaluations.
Materials and Methods The hDP-SCs were divided into four groups: control: hDP-SCs in Dulbecco's modified
Eagle medium + 10% fetal bovine serum group; hDP-SCs in 1% A-PRF group; hDP-SCs in
5% A-PRF group; and hDP-SCs in 10% A-PRF group, which were planted in 24-well (5 × 104 cell/well). The migratory speed rate of all groups was measured by using cell migration
assay (scratch wound assay) after 24 hours. Cell characteristics were evaluated under
microscope (Inverted microscope, Zeiss, Observer Z1, UK) that can be read through image-J interpretation. This image J represented the measurement of migratory speed rate
(nm/h) data. Statistical analysis was conducted using one-way analysis of variance
and post hoc Tamhane's test (p < 0.05) (IBM SPSS Statistics Software, version 22.0).
Results There was a statistically significant difference in the migratory speed rates of
hDP-SCs among various concentration groups of A-PRF (1, 5, and 10%) compared with
the control group.
Conclusion The increase in the migratory speed rate of hDP-SCs was highest in 10% A-PRF group.
