Note: LL—the relative length of structure in section (% from length of section); AA—relative area of structure in section (% from section area); NA—the numerical density of cells per 105 μm2 of the section area; #—values significantly differing from the corresponding on the 3rd day after the surgery (p ≤ 0.05); $—values significantly differing from the corresponding on the 7th day after the surgery (p ≤ 0.05); *—values significantly different from the corresponding ones after implantation without MSC EVs (p ≤ 0.05).
