| Реферат: | eng: One of the main unsolved problems in traumatology and orthopedics is reconstruction of critical-sized segmental bone defects. We believe that implementation of noninvasive monitoring of the bioengineering stages for cell-mediated bone scaffold by laser-induced fluorescence (LIF) can become a positive aspect in mastering this technique. An electrospun scaffold model (parameters: 10 wt. % polycaprolactone; 5% wt type A gelatin; mean fiber diameter 877.1 ± 169.1, and contact angle 45.3°) seeded with BHK IR cell culture (182 ± 38 cells/mm2) was used to show the principal possibility of differentiating between the scaffold seeded and unseeded with cells. First of all, the fluorescence spectra of the cell-seeded scaffold contain a peak at 305 nm for the excitation range of 230-290 nm, which can be used to differentiate between the samples. An increase in fluorescence intensity of the cell-seeded scaffold in the range of 400- 580 nm upon excitation at 230-340 nm is also noticeable. The wavelength of 250 nm is characterized by high signal intensity and is most suitable for differentiation between the samples. © 2016 Author(s). |
