“…F I G U R E 4 Schematic description, adapted from Li & Mooney, 2016, of the link between hydrogel matrix properties and drug delivery in the context of hydrogel deformation, swelling, and matrix degradation Although rare in the PNI repair field, mathematical models of slow flow dynamics in other fields could be adapted to describe, for example, the impact of minipumps, injections, and the contribution of microvasculature-induced flows. Cancer modeling is a ripe field for technology transfer, not only through the development of sophisticated mathematical models of microvascular and extravascular flows (Berg et al, 2022;Dogra et al, 2020;Shipley et al, 2019;Stamatelos et al, 2014;Sweeney et al, 2019), but also by highlighting the importance of experimental and/or imaging data to characterize these flows in situ (d 'Esposito et al, 2018). Similarly, mathematical models of fluid flows in tissue engineering and regenerative medicine is evolving to become a rich research field including, for example, describing perfusion of fluid in and around hydrogel-based constructs (O'Dea et al, 2012;Waters et al, 2021).…”
