OPA1 can even partially improve defects caused by complete lack of mitochondrial CI via an unknown mechanism.
Although oligonucleotides have been employed successfully to improve defects associated with other microsatellite disorders, they may not be ideal for r CGG exp because it is highly structured and because depletion or inactivation of the FMR1 mRNA via antisense or RNAi pathways could exacerbate disease; fragile X syndrome is caused by loss of FMRP.
This work aims at improving defect tolerance in FPGAs which are certainly affected by technology downsizing.
Specifically, they reported significantly improved defect filling, border repair integration and surface tissue repair along with far less evidence of fissuring and fibrillation in OLTs treated with BMAC (Hannon et al. 2016).
The treatment of PLLA incorporated with bFGF improved defect filling compared with that left untreated, while the regenerated tissue was mainly fibrocartilage and showed little bone formation with only a small amount of collagen type II (Col II) and no aggrecan gene message measured.
Histomorphometry revealed significantly improved defect repair in the osteoporotic ABM/P-15 group compared with the empty group.
In particular, optimizing surface chemistry, improving defect yield, and simultaneously reducing the size and preventing aggregation are still issues.
In addition, statins improved defect regeneration when locally applied in cranial/mandibular bone defect models without metal implants [ 15- 17, 36].
Consequently, recent systematic reviews have concluded that although scarce available evidence suggests that FGF-2 significantly improves defect fill but it does not have an effect on clinical attachment level gain [ 56].
Although these cell-free approaches reproducibly led to good healing efficiency, combinations of ASC and recombinant BMP-2 were also used (Refs 137, 138, 139, 140, 141, 142) (not listed in Table 4), but only Levi et al. described that ASC improved defect repair in comparison to the BMP-loaded scaffold alone (Ref. 142).
