However, in the case of in vitro assays, the salt conditions and redox potentials influenced the reactions massively, which could explain observed repair differences between the species [ 48].
In general, NHEJ is the more frequently observed repair pathway when using Cas9-mediated genome engineering, even in the presence of a donor HDR template [ 9– 12].
Despite this, we were able to observe repair of both strands, both nick-directed and non-nick-directed repair, depending on the junction conformation.
The ESDSA model accounts for the formation of large, interspersed blocks of old and new DNA observed in repaired D. radiodurans chromosomes.
Here, we also observed efficient repairing of the homozygous mutation to heterozygotes or WT bases as shown by Sanger sequencing.
No damage was observed in the repaired region; however the plastic hinge relocated just above the repaired region.
There also appeared to be good integration of tissue at the margins of the repair site, with flush and smooth surfaces, and good thickness observed on the repaired cartilage.
Correspondingly, lower T2 values were observed for repair tissue after Mfx as compared to MACI repair tissue, while no differences in Lysholm or MOCART scores were detected [ 132, 144, 155].
At necropsy, sutures had loosened in the post-ESD animals, although only minor deformity of the ulcer edges was observed in all repaired post-ESD ulcers.
The difficulty of accessing cheap spare parts or difficulties during the disassembly process are the commonest problems observed by repair technicians.
