“…Moreover, hydrogel wound dressing has good deformability and is helpful for wound repair [ 75 ]. Due to the ability to cover the postoperative site and maintain the continuous release of drugs, hydrogels even have great potential in preventing tumor recurrence [ 76 ]. Through the engineering design of hydrogels, precise control of RNA therapy can be achieved from the hydrogel loading and controlled release of RNA [ 50 ].…”

Hypodontia (dental agenesis) is a genetic disorder, and it has been identified that the mutation C175T in PAX9 could lead to hypodontia. Cas9 nickase (nCas9)-mediated homology-directed repair (HDR) and base editing were used for the correction of this mutated point. This study aimed to investigate the effect of HDR and the base editor ABE8e in editing PAX9 mutant. It was found that the chitosan hydrogel was efficient in delivering naked DNA into dental pulp stem cells (DPSCs). To explore the influence of the C175T mutation in PAX9 on the proliferation of DPSCs, hydrogel was employed to deliver PAX9 mutant vector into DPSCs, finding that the PAX9-containing C175T mutation failed to promote the proliferation of DPSCs. Firstly, DPSCs stably carrying PAX9 mutant were constructed. Either an HDR or ABE8e system was delivered into the above-mentioned stable DPSCs, and then the correction efficiency using Sanger sequencing and Western blotting was determined. Meanwhile, the ABE8e presented significantly higher efficiency in correcting C175T compared with HDR. Furthermore, the corrected PAX9 presented enhanced viability and differentiation capacity for osteogenic and neurogenic lineages; the corrected PAX9 even possessed extremely enhanced transcriptional activation ability. In summary, this study has powerful implications for studies into base editors, chitosan hydrogel, and DPSCs in treating hypodontia.

“…[16] Similarly, the FT-IR analysis of PEP-AD revealed that a new peak appeared at 1567 cm −1 , which was attributed to the amine (─NH 2 ) groups of adipic dihydrazide (Figure S2B, Supporting Information). Further, 1 H NMR analysis for PEP-AD showed the characteristic chemical shifts of PEP-AD at 2.7(a), 1.5(b), 1.7(c), and 3.0(d) ppm (Figure S2C, Supporting Information). [17] These results suggested that OPEP and PEP-AD were successfully synthesized.…”

“…[2b,3] Among them, injectable hydrogels provide resolutions for repairing irregular wounds, such as tumor surgeryderived wounds, because they can perfectly fill the rough surfaces of these wounds and can be utilized in minimally invasive surgical treatments. [1,6] However, obstruction of injection tools due to postponed operation or spread of the hydrogel to surrounding tissues of wounds would usually occur. [7] The shearthinning property of an injectable hydrogel may offer solutions to these issues, because it can improve the viscous flow of hydrogel mixture before injection and ensure hydrogel to be injected easily via a syringe.…”

Intraoperative bleeding and delayed postsurgical wound healing caused by persistent inflammation can increase the risk of tumor recurrence after surgical resection. To address these issues, Enteromorpha prolifera polysaccharide (PEP) with intrinsic potentials for hemostasis and wound healing, is chemically modified into aldehyde‐PEP and hydrazine‐PEP. Thereby, an injectable double‐network hydrogel (OPAB) is developed via forming dual dynamic bonding of acylhydrazone bonds between the decorated aldehyde and hydrazine groups and hydrogen bonds between hydroxyl groups between boric acid and PEP skeletons. The OPAB exhibits controllable shape‐adaptive gelation (35.0 s), suitable mechanical properties, nonstimulating self‐healing (60 s), good wet tissue adhesion (30.9 kPa), and pH‐responsive biodegradability. For in vivo models, owing to these properties, OPAB can achieve rapid hemostasis within 30 s for the liver hemorrhage, and readily loading of curcumin nanoparticles to remarkably accelerate surgical wound closure by alleviating inflammation, re‐epithelialization, granulation tissue formation, and collagen deposition. Overall, this multifunctional injectable hydrogel is a promising material that facilitates simultaneous intraoperative hemorrhage and postsurgical wound repair, holding significant potential in the clinical managements of bleeding and surgical wounds for tumor resection.
